OSB (OSB) boards or otherwise OSB sheets are widely used for building walls in houses, in particular in frame construction. Therefore, the issue of their exterior decoration is very relevant today. Moreover, not only from an aesthetic point of view, but also in terms of protecting the material from the negative effects of external factors (high humidity, sudden changes in temperature, solar radiation, and others).

In this article, we will consider the following question: OSB finish outside Houses.

Finishing OSB outside Finishing walls from OSB slabs outside the house: how OSB walls are finished

There are many different ways to finish walls from OSB sheets outside the house. All of them take into account the features of OSB boards, which are subject to the same deformations as wood.

Among the main applied methods of external wall decoration from OSB sheets, the following can be distinguished:

OSB house painting

Painting is the simplest and most common option that does not require a lot of time and money. Water-based or oil paints on wood are used for external work. In order for the coating to hold well, it is important to properly prepare the surface for painting. First of all, it is recommended to seal the interpanel seams with acrylic sealant, and then thoroughly clean and prime the entire surface of the boards. The paint is applied in several layers. Each of them must be allowed to dry well before applying the next layer.

Painting OSB boards

For painting OSB boards, you can use a brush or roller.

Applying plaster on OSB boards

Plaster allows you to extend the life of the plate and additionally protects it from fire. OSB boards can change their geometric dimensions over a wide range due to changes in humidity and temperature. environment. If you apply plaster directly on the OSB board, then soon it will become covered with cracks and peel off from the base. Therefore, two main technologies are used: the use of an intermediate layer and the layer-by-layer application of plaster.

Plaster OSB boards

As an intermediate layer, you can use expanded polystyrene or glassine. Expanded polystyrene has good moisture insulation and further improves thermal insulation properties walls. Glassine or bitumen cardboard has a low price.

To prepare the base, a sealant is applied to the joints between the sheets. The sheets themselves are primed. After that, an intermediate layer in the form of expanded polystyrene or glassine is glued. A reinforcing mesh is fixed on top of this layer and a layer of plaster is applied.

When applying plaster directly to OSB sheets, the process is divided into several stages. After preparing the base, as in the previous version, proceed to the first stage. During which the first layer of plaster is applied, a reinforcing mesh is sunk into it. After drying, another layer is applied. After it, a leveling layer is applied.

The option without an intermediate layer is less reliable and after 2-3 years the plaster may begin to peel off, so it is usually recommended to use an intermediate layer.

Installation of decorative stone on osb plates

Artificial stone is one of the most complex and expensive ways of finishing. However, excellent appearance finished facade And the durability of such a coating will certainly pay for itself over time. Stages of work:

Before starting work, the seams of the OSB boards are filled with frost-resistant sealant, the boards are primed.
Styrofoam is glued on top.
Then it must be puttied with frost-resistant putty.
Then apply two layers of glue. In the first, drown the reinforcing mesh.
Plant a decorative stone on the second layer.

OSB finishing decorative stone slabs

Sometimes a decorative stone is glued without an intermediate layer in the form of expanded polystyrene. This option is less reliable and after 2-3 years the coating begins to peel off.

Mounting siding on OSB boards

Siding is a universal finishing method that can be used for any facade. The material has an affordable cost and excellent appearance. Provided that the OSB board has a flat surface, fastening the crate is optional. At the same time, so that during operation the material does not swell from the resulting condensate, it is important not to forget to install a windproof waterproof membrane between the plates and the siding.

Finishing OSB boards with sidingDecorative facade panels

Decorative facade panels have a wide range of modifications and are made using various materials: wood, metal, plastic, glass. The technology of mounting such panels depends on the panels themselves. Most often for fastening are used: dowel fasteners, brackets and metal profiles.

Installation of decorative panels on the walls of the house from OSB

Each of the above methods has its own advantages and disadvantages. It doesn't matter which one you prefer. The main thing is to strictly adhere to the recommendations of experts and the right technology.

Ways to finish osb outside

Many builders sheathe the outer part of the OSB house (OSB, OSB) with a slab. This material is affordable, and differs high quality. When it comes time for the final work, do the craftsmen think about how to paint the OSB slab on the facade of the house? For the right choice, you need to study all the possible options used for this product.

What is OSB board?

The first OSB boards were created already over thirty years ago during mass buildings from frame materials. Most of the inhabitants of Canada, the USA and many Europeans live in such houses.

For the first houses made using frame technology, it was required Durable, weather and moisture resistant lining. Wood for installation of this type was not suitable, since its installation took too much time and effort.

Traditional fiberboard panels also failed to be used for their intended purpose, because they were too heavy. In addition, experts noticed that such material is afraid of fumes.

After selecting the options, a special technology was developed, which was based on laying long chips. The chips are glued together under the influence of wax and special resins that can withstand moisture.

OSB panel technologies allow without special financial costs build a house from a frame with a reliable facing material. This type of panels can be affected by any of the carpentry tools designed for sawing.

The panels are applied to the façade of the building using a joinery adhesive, which is made on a synthetic basis.

OSB panels are divided into four types according to the degree of strength:

OSB-1 are panels that are often used in rooms with a dry microclimate prepared for work. It should be noted that this type of panels is used only in interior work;
OSB-2 is also used for interior decoration of premises, such as bedrooms or living rooms. But an important condition is the presence of dryness in the home;
OSB-3 class boards are made with increased strength and resistance to wet influences. They are suitable for indoor and outdoor work;
One of the most durable plates is OSB-4. It is able to withstand significant loads and is durable. The cost of the material is much higher than that of other types of panels.

Often used in construction OSB-3, as it has a democratic price, and fulfills the basic requirements for quality products.

Finishing methods

Masters who have completed work with OSB panels in facade work often consider the material that is best suited for finishing. The choice of material should directly depend on the performance that the craftsmen plan to endow the house with.

Painting

This is one of the simplest and most economical methods, but work must be done carefully. One wrong application can spoil the overall look of the tiles. When carrying out surface painting work, the following rules must be remembered:

In the paint selected as the surface coating material, must not contain water. Excess water will cause the panels to swell and ruin the product.
In the process of work, you need to pay Special attention on the edge of the slabs and paint over these places abundantly.
Experts recommend using paint on oil based when carrying out such work. This paint does not harm the structure of the panels and is deeply absorbed, creating a rich color.
In order for the texture to be completely dyed, you need to apply paint in several layers. We must not forget that for each layer must be given time to dry.

Sometimes the owner of the house wants extra protect walls with fire retardant, but you need to take into account the fact that not all paints are combined with such impregnations.

In such cases, priming the surface will be an additional treatment that will be between the impregnation and the paint layer.

Plastering

This option OSB coatings panels the most demanded and justified for outdoor work. This type of finish is a number of features:

experienced craftsmen additional waterproofing surfaces with liquid rubber or roofing material;
for more stability apply plaster mesh , which will prevent the formation of cracks;
used for meshing special composition for reinforcement in facade structures;
performing plastering work external facade accepted finish with a layer of decorative plaster, which will not only be a strong protection against external influences, but also give the building a characteristic personality.

siding

The use of sheathing with siding panels is an economical way to improve the appearance of the building.

Siding can be fixed to the installed OSB surface.

The options for siding panels are presented in large numbers, so if you wish, you can choose a model that imitates a block house or brickwork.

The advantage of such a sheathing is that if OSB boards are already glued to the side of the facade, it is not necessary to mount an even frame. However, can't do without a membrane which will protect from wind and moisture.

If you do not put this additional fastener, then the siding will periodically sweat from the inside, and the OSB will swell under the influence of moisture.

If you choose between two types of siding panels - PVC or acrylic, then you can stop at any type, since there are no significant differences between them.

Facing products are produced in one thickness, varying from 0.8 to 1.3 mm. They can withstand temperatures up to 80 degrees Celsius, and exposure to sunlight, under which they do not fade.

Both types are highly resistant to the spread of fire and chemicals of chemical origin. Acrylic panels are rich in color, but otherwise almost indistinguishable from PVC products.

How to plaster the slab outside the house?

The question of whether it is possible to putty the surface of OSB boards is debatable: some experts believe that this coating will not protect the product from the appearance of cracks on the surface of the facade. Others, on the contrary, recommend using an additional coating, because it will refresh the gloomy wood panels and serve as a protection against moisture and dust.

Carrying out high-quality work on plastering the facade of the building can be performed subject to the following conditions:

the surface must be coated with an adhesive before work;
the solution applied to the surface with a spatula should not be thinner than three millimeters;
the use of a reinforcing mesh after applying the first layer;
coating the surface with an adhesive composition after the first layer has dried.

The surface of OSB slabs visually looks decent, and some homeowners leave them at this stage and do not commit additional work on the cladding of the building.

Many experts still recommend covering the slabs with plaster - this will not only give the house individual features, but also protect against external damage. In order to perform plastering with high quality, you need to follow the sequence of work:

When applying the first layer, you should try to draw a wide spatula along the wall to fill all the recesses on the OSB. For proper application, you need to drive the tool along the wall in arcuate movements. The completion of the first layer must not be accompanied by streaks along the surface to be coated.
After the first layer is completely dry, the wall is cleaned with an abrasive mesh and the application of putty is repeated.
In order to achieve a perfect surface with a smooth sheen, you need to apply at least five successive coats.
After applying the putty, the surface must be dried, after which a layer of paint can be applied to it.

The question of what is the best way to carry out work on puttying panels is asked even by experienced craftsmen. The work process can be complicated by the fact that most putty materials do not stick well to a surface made of wood.

Therefore, you need to choose those models of coatings that have the highest adhesion to the wooden surface.

In order for the work to be completed successfully, it is recommended to pay attention on a mixture of Rodband and Goldband. These mixtures are made on a gypsum basis with impurities from polymeric materials.

If the owner of the premises wants to save on putty material, then it is better to purchase Rodband, its texture is more rigid than that of Goldband, and the price is much lower.

The choice of finishing is also important, and it should be approached thoroughly. In order not to make a mistake with this choice, it is recommended to purchase mix Vitonit KR.

Porcelain stoneware installation

Porcelain tiles are applicable for sticking to OSB walls, but is it necessary to carry out such serious work, which, moreover, can harm building structures?

Porcelain stoneware tiles are resistant to fungal formations, moisture and mold. One of the most important advantages of this material is considered to be sustainability and an extensive range of products in stores. All these advantages are suitable for internal work, but not external.

OSB panels can be tiled indoors, for example on the floor, but outdoor work is not recommended.

Masters do not use porcelain stoneware in facade work for one main reason - wall surface must be ventilated in order to avoid waterlogging and swelling of the panels.

Means for staining OSB

Apart from water-repellent protection, paint coating provides a number of advantages for the surface:

the coating is able to protect wooden surfaces from premature deformation;
if large chips are visible on the surface of the wall, then they can be easily hidden after applying the impregnating solution;
compared to other materials, painting is quite cheap and is not inferior in protective qualities.

Usually, OSB-3 or OSB-4 are used for finishing from the street, which are most resistant to weather phenomena. Not every owner can purchase OSB-4, since this material is characterized by high cost and resistance to mechanical stress. If the "four" is fully protected, then OSB-3 requires additional coverage.

Plates are made from wood, which is the main component of the product, endowing it with environmental properties. At the same time, such a natural composition makes the wood product vulnerable to the onslaught of weather conditions.

You can give additional protection with siding, artificial stone or the most common and easy-to-install material - paint.

When choosing a composition suitable for outdoor use, you can pay attention to all mixtures intended for working on wood surfaces.

Coatings that spoil the appearance of the facade should be avoided. These include glaze substances and gloss varnishes. These compounds will expose the texture of the chips to the public and emphasize it, and it does not have a special appeal. Therefore, it is better to refuse such products.

The following compositions are suitable for covering OSB boards:

Compounds made of latex.
Alkyd paint.
acrylic blends.
Oil mixtures.

They used to be widely used, but today they are almost out of use. This happened in connection with the displacement of this mixture by other more popular ones.

Oil suspensions toxic in composition, and the work has to be carried out in special masks or a respirator. The oil dries for too long and spreads over the painted surface, which of course implies additional forces to restore the wall and eliminate smudges.

After carrying out work on applying the suspension, rags often form that spoil the appearance of the facade. Another unpleasant property of this paint is the inability to cover it with a new composition that differs in components.

In order for the painting work to be completed successfully and without additional efforts and tinting, you need to remember a number of features of the wooden material:

if there are sharp protrusions on the building, they will contribute to the spreading of the paint composition. If there are such corners, they need to be rounded off, as in a plasterboard;
the edges and joints of the plates must be puttied to eliminate possible difficulties in applying and making the wall smooth;
the question of whether to prime the surface between wood and paint should not arise, because there is a clear answer to it - yes. This action is essential for accurate adhesion between paint and material;
if the owner wants to achieve an even application of the composition over the entire surface of the wall, he will need to finish the putty on all the plates;

The number of times for applying paint is determined individually, but experts advise painting at least four times. After abundant absorption of paint in wooden surface the color of the product will become saturated, and the strength of the composition will increase markedly.

It is important to remember that each layer has its own time to dry, and you should not start painting before the previous mixture has dried.

How to choose OSB for exterior walls

The first oriented strand boards appeared in countries where the culture of frame construction has long been developed. Thanks to their excellent technical properties, they immediately came to the court, and over time, the material became even better.

Now OSB is used as a structural and sheathing material almost on a par with plywood, but at a significantly lower cost. Such sheets are used in the construction of any type of buildings: creating roofs, when filing ceilings, when assembling floors ...

However, sheathing the “pie” of light frame walls is, in fact, their real vocation.

OSB boards for cladding frame buildings

What is required from OSB for facade cladding

OSB boards as cladding for external walls offer a number of important advantages. All of them are due to the high standards that are imposed on light construction.

Moisture resistance and water absorption.

According to modern standards, oriented strand board must freely withstand conditions that are considered “normal” (about +20 degrees temperature and about 65 percent humidity). This is enough to be able to clad the frames of the outer walls from the side of the premises. But also OSB on the facade should easily withstand atmospheric precipitation, which can occur during the construction of the house, when the roof and finishing finishing materials are not yet available.

Spatial strength.

OSB boards on the frame of the cottage do not just sew up the spans between the racks and not only keep the insulation in place. Sheet material after fixing on the frame unfastens the racks, improves the connection of the racks with the strapping boards. A slab sewn onto a wall is so “useful” for a frame that it even eliminates the installation of braces and struts, which are usually used to stabilize walls in the transverse direction. It so happened that OSB, created under high pressure from specially prepared wood chips and resins, is a durable load-bearing sheet that copes with all the tasks on the facade. The material is not afraid of compression, bending, delamination ... In terms of physics, it is slightly inferior to high-quality plywood, but much stronger, for example, chipboard.

The ability to hold fasteners.

It is not often that sheathing acts as a rough power and at the same time as a finishing decorative material. It is mainly then lined with something else, and very often the finishing facings are screwed or nailed onto the resulting slab base. OSB has enough density and uniformity of solid wood properties to hold nails or self-tapping screws very well.

Large size, shape stability.

When choosing OSB for exterior walls, as a rule, developers value impressive dimensions. This makes it possible to work quickly, have fewer joints, and more reliably assemble more elements together. In the case of high-quality, factory-made OSB, we note very small tolerances in thickness, width and length of the panels. That is, by sheathing the frame of the house with this sheet material, we get very accurate technological gaps, as well as even planes without drops and ledges. There are no knots, no voids, no irregularities in the sheets. Products of various sizes are available to the consumer, including at the enterprise you can buy OSB with individual dimensions on order.

Possibility of using traditional technologies.

The pace of construction and the cost of ongoing work - that's what else they pay attention to. Sheet oriented strand material, chosen for facade cladding, should be easily cut, planed, pierced with nails ... The ability of OSB to stick together after priming, as well as the possibility of painting panels, will not be superfluous.

insulating properties.

By default, facade walls require high insulating characteristics, because this is the most important enclosing structure. Since OSB is a wood-based board, the fibers of softwood chips (which form the basis of the sheet) at least do not worsen the thermal performance of the walls, they definitely improve their sound insulation.

Fire resistance.

It is clear that for sheathing ( STRUCTURAL cladding) exterior walls, it makes sense to use materials that are resistant to fire. Oddly enough, but both plywood and OSB meet fairly strict standards and are well suited for any cladding in civil engineering. And if the outer walls sheathed with oriented strand board will contain mineral wool (especially basalt), then the fire resistance of the structure will be even better.

Environmental Safety.

Load-bearing frame walls must be clad on both sides. But the material used indoors must be suitable for this. Making a choice in favor modern plywood or quality branded OSB, we get boards with a very low emission of volatile substances. Oriented strand board sheathing meets the E1 formaldehyde class, which is an excellent option.

Aesthetics.

Boards made of pressed wood chips (especially OSB-3 European production) are pleasing to the eye. As a rule, they are sanded on both sides, the wood chips lie evenly and tightly in their place. The wood used is clean, without bark and obvious blackening. Homogeneous natural pattern of natural wood is clearly visible through a transparent binder. That is why OSB is often used not only for structural stitching on frame posts, but also as a finish inside and out.

How to choose the right OSB model for facade cladding

If we consider an OSB board produced and certified according to American standards, then to create an external wall, you should use a material with the index W (wall sheathing), or roofing material with a letter index R is also suitable here.

As for the OSB brand for strength, manufacturers suggest using boards with a grade from 16 to 24, where the numbers indicate the maximum allowable distances between supports in inches. At the same time, for an accurate choice of thickness, it is very important what material will be used as a finishing material, whether it will be mounted directly on the OSB or whether it will be fixed by means of girders or vertical elements of the auxiliary frame.

According to European standard, suitable for cladding frame houses from the side of the facade will only be panels of a brand not lower than OSB-3. Only they, as well as OSB-4 boards, have sufficient strength and sufficient moisture resistance.

OSB thickness that can be applied on facade walls, is directly dependent on the step between the racks. The larger the step, the thicker it is necessary to choose plates for cladding. The minimum thickness that can be applied for structural sheathing is 9 mm, while the average can be considered a thickness of 12-15 millimeters with a step between posts of 600 mm. The maximum thickness of the structural sheathing, which is economically and technologically feasible, is 20-22 mm.

Plastering walls from OSB boards

OSB painting

If the OSB is fixed as an additional layer on an already existing structural cladding, then sheets with a thickness of 7-7.5 mm can be ordered. In terms of size, it is necessary to choose OSB for wall cladding along the frame, taking into account generally accepted technological maps. First of all, it must be borne in mind that both horizontal and vertical installation of plate materials is allowed on the facade. In any case, the OSB boards must go on the boards of the upper and lower strapping of each floor, then a complete and continuous dressing is ensured in the frame house from the foundation to the roof. Moreover, if the sheets have a width of at least 1200 mm, then you can not use diagonal struts or short transverse struts in the design.

The cladding elements are fixed on the frame with a gap of 3 mm, and it is recommended to seal the resulting seams with sealants or cover with construction tapes. It also makes sense to treat the edges of the material with a paintwork material.

As an option, until the OSB on the street side of the house is protected finishing material with normal waterproofing abilities, the seams can be closed with the help of flashing strips or generally made in the form of a horizontal connection of plates with an overlap of 40 mm.

OSB is the cheapest coating option, the price of which does not correspond to the lowest quality.

However, OSB consists of resins and chips, so it absorbs moisture. To prevent this from happening, OSB boards must be covered with a layer of something solid so that moisture does not enter inside.

Also in the article you will see practical tips how and where is it better to install the OSB board.

Where are OSB boards used?

OSB boards are very cheap and at the same time reliable, so they can also be seen on trucks and trailers.

However, problems arise only when installing floor and wall coverings. Including facing works in frame houses.

OSB surface finish for flooring

If you want a flat floor, OSB poasty is the most the best choice. So that the floor does not sag later, it is better to use OSB-3.

Such plates are very thick and therefore can withstand heavy loads. They can be placed on wooden logs or concrete screed.

As with any other type of coating, it is better to apply many thin layers than one thick one.

When applying, make sure that each layer has time to dry well and does not stick to your fingers. The plates themselves must be polished.

However, polished slabs are often not available in the store or they are expensive. To get out of the situation, sand the surface yourself or cover it with wood primer.

Linoleum or carpet

If the plates are covered with linoleum or carpet, they may fog up.

To avoid this, seal the gaps with resin or glue. To avoid gaps, use plates as thin as possible.

Tile

When attaching tiles to OSB, choose one that can bond ceramics and wood together as a bonding material.

Laminate

If OSB boards are the basis of the laminate, this is the best option.

This is not only the best bonding of materials, but also the most even styling.

Finishing of internal partitions

In the manufacture of plates, different resins and adhesives are used.

At certain temperatures and other influences, the substances that hold the material together can act on the surface.

For example, if you cover the tiles with wallpaper, this wallpaper will be covered with small and large greasy spots.

To prevent this from happening, use a primer before applying any coatings.

Be careful: if the manufacturer has waxed the surface, the primer must contain quartz sand.

The varnish should be applied in a large number of thin layers.

If you are using paint, it must be for wood. If it contains water, it will make the wall breathable. But when applied water-based paint plate may be twisted. Therefore, it is worth considering the conditions in which the stove will be located.

The wallpaper is glued to ordinary wallpaper glue with the addition of PVA.

External finishing of OSB boards

In direct contact with the external environment, the plate constantly runs the risk of twisting from dampness. To prevent this from happening, a protective layer of paint must be applied to the plate. When painting osb boards, ordinary paint for facade work is used.

You need to follow the cracks. All of them must be filled with acrylic sealant.

To better apply the paint, it is better to round off all sharp edges. In this case, the radius of the circle must be at least 3 mm.

All surfaces are primed and sealed.

After applying the primer, if it contained water, the surface must be sanded.

If you choose a transparent dye, please note that it should not let in direct sunlight. Otherwise, the plane will dry out and deform because of this.

It can be summed up that such a plate is very cheap to buy, but just as reliable as an array. What's more, you can use the same coating that is used for normal boards.

The only negative is the vulnerability to moisture, which can be compensated with varnishes, primers and paints on the surface itself and resin with glue at the joints.

Material selection

There are several types of materials that meet these requirements to a greater or lesser extent: moisture resistant plywood, DSP, OSB, edged board, fiberboard. They have similar characteristics and are widely used in frame construction. To make a choice, it is worth familiarizing yourself with the main properties and features of each of them.

The use of OSB in frame construction

OSB panels rightfully belong to the most demanded materials in the arrangement frame structures. They consist of layers of glued wood chips and chips, and in the outer layers the fibers are arranged longitudinally, inside - transversely. Synthetic resins and wax are used to bind the chips, giving the finished boards water-repellent properties.

Standard production provides for the production of these plates in several categories:

OSB-1 is intended exclusively for interior decoration of dry rooms with reduced mechanical stress;
OSB-2 is used in the installation of load-bearing structures in rooms with low humidity;
OSB-3 is a moisture-resistant board of increased rigidity, used in the installation of load-bearing structures indoors and outdoors.

In addition to the main components, the composition contains hydration additives, the mass fraction of which does not exceed 3%. DSP is characterized by resistance to moisture, high strength, long service life. Plates are widely used in private construction, industrial, for work inside and outside the premises.

GVL consists of pressed gypsum reinforced with cellulose fibers. Due to its high strength, the material is suitable for creating load-bearing surfaces, therefore it is widely used in frame construction. It differs from drywall in greater density, uniformity, and the absence of a cardboard shell. In terms of frost resistance, soundproofing properties, as well as resistance to moisture and combustion, GVL is also several times higher than gypsum boards.

Installation of GVL is carried out in a frame and frameless way. For external wall cladding, the first option is used, where the sheets are fastened to the bearing racks with self-tapping screws. The material is easy to cut and drill, and, despite its heavy weight, is quite easy to install. Such a sheathing serves as an excellent basis for finishing with tiles and decorative plaster.

Construction of a frame house

Sheathing can be done in two ways - with and without crate. In the first case, the vapor barrier layer is located between the frame and the OSB, in the second - on top of the skin. The batten option is used in cases where the OSB serves as the basis for plastering, painting or tiling, the second method is used, as a rule, when installing a ventilated facade. Otherwise, there are no significant differences.

Step 1. Start trimming from the very corner. The first sheet of OSB is applied to the racks of the frame so that the lower edge completely overlaps the lower trim of the house. Be sure to control the horizontal level. The plate itself is also recommended to be placed horizontally, and not vertically - this provides the structure with greater rigidity. For fixing the material, galvanized self-tapping screws with a length of at least 50 mm are used. About 10 mm must be retreated from the edge of the OSB, the fastening step along the perimeter of the sheet is 15 cm, in the center - 30 cm.

Step 6 Next, the laths of the crate are stuffed for finishing in increments of 50-60 cm. The laths must first be treated with a protective compound and dried. After that, you can proceed with the installation of siding, lining or other decorative coating for the house.

On a note! If it is planned to paint the facade from OSB, then the membrane, respectively, is mounted only with inside Houses.

With this method of sheathing, the insulation is placed on the inside of the walls into the cells of the frame and covered with a vapor barrier film. Slabs for interior decoration are sewn on top of the vapor barrier, for example, drywall or the same OSB.

Video - How to sheathe a frame house outside

OSB (OSB) or OSB (oriented strand board) is a modern structural material that has become a serious alternative to plywood, chipboard and is widely used in the construction of frame houses and the decoration of buildings and structures. OSB boards are sheathed on interior and exterior walls, floors and roofs. Wall cladding with OSB boards takes place in frame construction when the board protrudes structural material and serves to reinforce the walls of a building, or when acting as a facade material of concrete, brick or wooden houses, which is caused by a low price and high strength and durability of the material. In this article we will consider the question: how to fix the OSB boards to the wall from its outer side.

For cladding exterior walls, it is necessary to use boards with the OSB-3 brand, specially made for environments with high humidity. About how the types of OSB sheets differ can be found on the page: OSB sheets, their types, characteristics, sizes.

At OSB installation slabs to external walls, lathing are used for the following purposes:

alignment of the plane of the wall;
creation of a ventilation gap for insulation under the OSB plate;
prevention of deformation of the slab caused by base movements, especially important for OSB slabs with a thickness of 9 mm or less.

Fastening OSB boards to the wall over the insulation using the crate

The slab is fastened to the wall using a crate, which is made of a wooden block or a metal profile. The technologies for mounting OSB boards on a wall with a wooden crate and a crate made of a metal profile do not fundamentally differ. When choosing a bar, it is advisable to choose a dry, planed bar of 40-50 mm, then it will not turn out and will not lead after drying, which will positively affect the evenness of the entire wall.

To attach the bar and profile to the wall, special metal plates (suspensions) are used. Before attaching the suspensions, it is necessary to draw vertical stripes on the wall, the distance between which should be half the width of the sheet, which subsequently will ensure the joint of the plates right in the middle of the bar or profile and will make it possible to fix the OSB plate in the center along its entire length. After the lines are drawn, hangers are attached along them in increments of 30-40 cm.

A metal suspension is used to fasten the crate. Hangers are attached along the marked lines. Hangers allow you to fix the crate over the insulation.

After that, the insulation is laid and covered with a membrane that protects the insulation from moisture, after which the crate is mounted.

It should be noted that a vapor barrier is not needed outside the building, since it prevents moist air from entering the insulation from inside the room, and from the outside of the building, excess moisture should freely go outside.

Wall with a crate. Insulation is laid between the crate and the wall.

After fixing the crate, you can proceed with the installation of OSB boards. For wall cladding, a plate from 9 to 12 mm thick is most often used. If a facade is not mounted on top of the slab, then the slab must be moisture resistant. OSB boards are fastened to a crate of wooden beams with nails at least 2.5 times longer than the thickness of the OSB sheet. To the crate from a metal profile - to self-tapping screws for metal 10-15 mm longer than the thickness of the OSB sheet.

With this installation, the crate weighs over the insulation, and does not create cold bridges in the insulation between the wall and the OSB boards. Thanks to this solution, maximum efficiency of the heater is achieved. In addition, between the bars of the crate there is an air gap through which moisture is removed from the insulation, which also increases its characteristics. More detailed information about the technology of a ventilated facade is in the article: ventilated facades, types of ventilated facades.

Fastening OSB boards to a wooden frame

When building frame houses with a wooden frame, two main approaches are used: fastening OSB sheets to the frame through the crate and fastening OSB sheets directly to the frame without crates. Consider the case of fastening OSB boards using a crate.

When strong plates are attached to the frame from the inside of the wall, providing good rigidity of the wall structure, then a crate can be made from the outside between the frame and the OSB board. The crate forms air cavities for ventilation of the insulation and reduces deformation loads from the frame to the OSB board.

Insulation is placed between the racks of the frame. On top of the racks and insulation, a wind- and waterproofing membrane is attached, which easily passes moisture. Next, the crate is attached and OSB boards are attached to it.

Installation of OSB boards on a wooden frame with a crate.

With this design, the plates can be left unfinished, you can paint them, plaster or fix almost any facade material on them.

When fixing OSB slabs without using lathing, the maximum rigidity of the wall structure is achieved. In this case, it is recommended to fix the wind and waterproof membrane behind the OSB plate, then mount the crate to create a ventilation gap and facade material, such as siding, boards or decorative panels, on it. OSB boards are fastened to a wooden frame with nails at least 2.5 times the thickness of the OSB sheet.

The advantage of using nails over self-tapping screws when fastening OSB from the outside of the house is justified by the fact that nails better tolerate deformations of OSB sheets under atmospheric influences.

The technology of fastening OSB sheets to a wooden frame without the use of crates.

For example, when building a frame house using the Finnish technology "Platform", there is no crate between the frame and OSB foxes. More details about this technology can be found in the article: construction of a frame house using the "Platform" technology.

Fastening OSB boards to a metal frame

Fastening is carried out similarly to the variant with a wooden frame. When fixing the plates directly to the metal frame, use self-tapping screws for metal 10-15 mm longer than the thickness of the OSB sheet.

General rules for mounting OSB boards to the wall

Regardless of the chosen method of fastening OSB sheets, there are general rules, compliance with which will ensure maximum strength, reliability and durability of the sheathing structure.

Self-tapping screws should be screwed at a distance of 10-15 cm from each other and at least 1 cm from the edge of the plate.
A gap of 10 mm is required between the bottom plate and the foundation to prevent water accumulation.
The plates cannot be butted close to each other, a gap of 2-3 mm is required between them so that the plate can expand freely from moisture changes.
All door and window openings are cut with a jigsaw or circular saw, but if you need perfectly even joints and cuts, then you can come with ready-made sizes and OSB sheets to furniture shop, where, for a small fee, your sheets will be sawn on a panel saw exactly and exactly in size.

Which side to mount OSB sheets

All sides of OSB sheets do not differ in composition. But there are differences in the surfaces. Often one side is smooth and the other rough. In this case, when mounting the plates on the walls from the outside of the building, it is better to fasten the sheets with the smooth side outward. With this orientation, rainwater will not accumulate in such quantities in the unevenness of the slab. Water accelerates the destruction of the plate. Protecting the sheets from water penetration into them helps to increase their durability.

When installing tiles on the roof under the roof, in turn, OSB sheets are recommended to be placed with the rough side up so that it is not slippery to walk on them during roofing work.

When installing OSB boards in places protected from moisture, the choice of their orientation does not have a significant impact on subsequent operation.

In this article, we will consider the following question: OSB finish outside Houses.

Finishing OSB outside Finishing walls from OSB slabs outside the house: how OSB walls are finished

There are many different ways to finish walls from OSB sheets outside the house. All of them take into account the features of OSB boards, which are subject to the same deformations as wood.

Among the main applied methods of external wall decoration from OSB sheets, the following can be distinguished:

OSB house painting

Painting OSB boards

For painting OSB boards, you can use a brush or roller.

Applying plaster on OSB boards

Plaster allows you to extend the life of the plate and additionally protects it from fire. OSB boards can change their geometric dimensions over a wide range due to changes in humidity and ambient temperature. If you apply plaster directly on the OSB board, then soon it will become covered with cracks and peel off from the base. Therefore, two main technologies are used: the use of an intermediate layer and the layer-by-layer application of plaster.

Plaster OSB boards

As an intermediate layer, you can use expanded polystyrene or glassine. Expanded polystyrene has good moisture insulation and further improves the thermal insulation properties of the wall. Glassine or bitumen cardboard has a low price.

The option without an intermediate layer is less reliable and after 2-3 years the plaster may begin to peel off, so it is usually recommended to use an intermediate layer.

Installation of decorative stone on osb plates

Artificial stone is one of the most complex and expensive ways of finishing. However, the excellent appearance of the finished facade and the durability of such a coating will definitely pay for itself over time. Stages of work:

Before starting work, the seams of the OSB boards are filled with frost-resistant sealant, the boards are primed.
Styrofoam is glued on top.
Then it must be puttied with frost-resistant putty.
Then apply two layers of glue. In the first, drown the reinforcing mesh.
Plant a decorative stone on the second layer.

Finishing OSB slabs with decorative stone

Sometimes a decorative stone is glued without an intermediate layer in the form of expanded polystyrene. This option is less reliable and after 2-3 years the coating begins to peel off.

Sheathing a frame house with wooden boards

After the final construction of the frame house, the installation of windows and doors, as well as the installation of insulation on the walls, it's time to move on to the next stage - sheathing the surface of the frame structure. Before each master at this stage, the question arises: what materials to use? You can use lining, siding, natural wood, ventilation facades or vinyl panels.

The best option in terms of appearance, price, durability and durability is the use of siding and wood panels.

Before carrying out the sheathing of a frame house from the outside, you need to do preparatory work.

First of all, you need to prepare a lining with a maximum allowable humidity in the range of 10-15%.

With higher humidity, after the installation of the panels, the shrinkage of the wood will begin, which will lead to deformation, displacement of the boards and the formation of numerous cracks.
It is recommended to carry out sheathing of a frame house at the end of summer or early autumn - at this time the action sunlight not as intense as in June or July.

Thus, it is necessary to purchase wooden boards a few months before the work, approximately in May-June. This is necessary for sufficient shrinkage of the wood, which lasts at least six to eight weeks.

After drying and preparation of materials, you can proceed to sheathing. Work is carried out from the bottom up. The second panel is positioned with the groove up while the tongue is directed down to secure with the starter board.

Expert opinion

Ask an expert

Laying boards must be carried out strictly horizontally - to check the position, you must use the building level.

The second board and those following it are fixed as follows: the spike is inserted into the groove, after which several blows are applied to the top board with a mallet to fix it. Blows must be applied carefully so that the walls of the grooves do not deform. At the edges of the panel, at a distance of 10 mm, the board must be fixed with two nails.

The entire panel must be fixed with nails along the length, while the step size must be 500 mm.
After the frame house is sheathed with wooden panels, it is necessary to fix two boards at the outer corners in the vertical direction, overlapping each other. In the same way, platbands are installed on window and door openings.
It is possible to carry out the outer skin of a frame house both horizontally and vertically.
After installing the wooden panels, you can start painting. Before this, it is necessary to prepare the surface of the walls so that in the future they are not rough or uneven. For this, a grinder with an installed abrasive of size 25-120 is used. Alternatively, an abrasive with a value of 40 can be used.

If oil painting is to be carried out, then before applying it, it is necessary to cover the wooden panels with two layers of drying oil. Only after that it is possible to paint the surface with a roller, spray gun or a wide brush.

Sheathing a frame house with siding

Siding panels have special perforated edges with slots through which fastening to the surface takes place with the help of nails or self-tapping screws. On the bottom of the siding panel there is a hole for condensate drainage.

The master will need the following tools:

Connecting strips
plastic siding
Building level
Kiyanka
corner

It is possible to carry out siding with the use of connecting strips, but to save money, you can overlap the connection without using strips.

Initially, preparatory work is carried out. Siding can be fastened in several ways: either on aluminum profiles, or directly on the surface of the walls.

Alternatively, instead of aluminum profiles, you can use ordinary wooden bars attached to the surface of the walls. This way of saving will save up to 30% of the funds that could be spent on cladding with aluminum frames.

After laying wooden bars (or installing an aluminum frame), sheathing can be carried out. At the lower corner of the crate, a starting bar is installed (in parallel, it is checked by a level for a horizontal position).

After the panel is level, you can fasten it to the racks with nails or self-tapping screws. The installation of the panels is carried out as follows: one of the ends of the product is inserted into the groove of the corner, after which the profile spike is inserted into the groove of the starting bar.

This type of connection is called a "lock" - if all the steps were performed correctly, the master will hear a characteristic click, which means the connection was successful.

On the perforated edge of the siding panel, there are slots that are designed to secure the panel to the wall surface using self-tapping screws or nails. After successful fastening, the second panel can be overlapped with the first.

The exterior cladding of the house with siding is carried out from the bottom up: first, starting strips are installed along the perimeter, then the second panels, third, etc. are mounted.

Sheathing a frame house with OSB boards

Also, OSB-plates can be used for sheathing a frame house.

Oriented strand boards are made from wood chips that are compressed under pressure and coated with synthetic resins. The main material of OSB boards is pine or spruce.

The plates are fastened directly to the walls, no additional frames or joints are required.

Sheathing is carried out as follows:

Work is carried out from the bottom up. After installing the first plate (and measuring the level), the second plate is installed. It is necessary to leave a small expansion joint (2-3 mm) so that in case of expansion of the building material, deformation does not occur
Self-tapping screws are mounted at the junction of the panels, which act as limiters. The length of the screws should be at least 50-55 mm.
Nails or self-tapping screws are mounted at a distance of 1.5-2 cm from the edge, a step of 15 cm is observed. Closer to the middle of the panel, the step can be increased to 30 cm

Sheathing with OSB boards is not only structural reliability and strength, but also significant savings in installation costs.

The main types of building materials for such structures are wooden beams, beams and OSB panels. It is the use of panels that provides the frame house with the characteristics that attract developers so much.

Houses built using frame technology have beneficial advantages. But, as the reviews show, these advantages can be achieved only with full observance of the technological process.

Final stage of work

In order to give the frame house more aesthetic appearance, it is recommended to install a finishing bar on top of the walls, and a plastic corner on the area between the pediment and the sheathing. It will help to correctly and securely fix the bottom bar, as well as hide visible joint panels.

In order for the ends of the panels not to be noticeable, you can use the finishing of window openings plastic corners instead of wooden architraves. One side of the corner is fixed near the window opening, and the other side will hide the visible ends of the panels.

If you have already selected the desired material and prepared the tools, you can proceed to the initial preparatory work. We wish you successful construction.

Requirements for outer skin materials

Wall cladding is one of the final stages in the construction of a frame house. And here the choice of material is of great importance: the microclimate in the premises, the mechanical strength of the walls, the reliability of protection against moisture and cold depend on this. In addition, sheathing serves as the basis for finishing materials, and in some cases acts as a finishing coating and is responsible for the aesthetic appearance of the building.

Sheathing gives the frame of the structure a certain rigidity and takes on part of the load. This means that one of the main criteria is the mechanical strength of the material in bending and compression, the absence of shrinkage during operation. The walls must retain their original shape for years, regardless of the surrounding conditions. In addition, the sheathing must be resistant to moisture, sudden changes in temperature, and the effects of microorganisms.

Next, you need to pay attention to the ease of installation of the material and its ductility during processing. If you plan to sheathe with your own hands, this aspect is of great importance, because it depends on how much effort and time it will take to work. The material should be easy to cut and drill, but at the same time keep the density on the cuts, not crumble, not crack. And, of course, it must be durable so that you do not have to change the skin every 10-15 years.

Material selection

There are several types of materials that more or less meet these requirements:

waterproof plywood,
cutting board,

They have similar characteristics and are widely used in frame construction. To make a choice, it is worth familiarizing yourself with the main properties and features of each of them.

Oriented Strand Board (OSB)

OSB panels rightfully belong to the most popular materials in the arrangement of frame structures. They consist of layers of glued wood chips and chips, and in the outer layers the fibers are arranged longitudinally, inside - transversely.

Synthetic resins and wax are used to bind the chips, giving the finished boards water-repellent properties.

Standard production provides for the release of these boards in several categories: OSB-1 is intended exclusively for interior decoration of dry rooms with reduced mechanical stress; OSB-2 is used in the installation of load-bearing structures in rooms with low humidity; OSB-3 is a moisture-resistant board of increased rigidity, used in the installation of load-bearing structures indoors and outdoors.

In terms of quality-functionality-price, OSB-3 is the most optimal, and this material is widely used in private construction for wall cladding, the manufacture of load-bearing partitions, and reusable formwork during pouring. concrete structures. The plates lend themselves perfectly to grinding, cutting, drilling, tightly hold nails even at a distance of 6 mm from the edge. Such sheathing can simultaneously serve as a decorative coating for walls, it is enough just to treat it with waterproof varnish or paint it.

OSB Advantages:

dense structure prevents delamination and splitting of the material during processing and during operation;
plates have elasticity and high strength, perfectly resist vibrations, compressive loads, various deformations;
the material is resistant to weathering and temperature extremes;
OSB is resistant to microorganisms, insects and rodents do not like it.

Flaws:

very low vapor permeability;
combustibility;
the content of toxic compounds (phenol and formaldehyde).

Cement particle boards (DSP)

This material is a compressed mass of M500 cement and shavings (usually softwood). A standard plate has three layers: the outer ones are made of small chips, the inner one is made of large chips.

In addition to the main components, the composition contains hydration additives, the mass fraction of which does not exceed 3%. DSP is characterized by resistance to moisture, high strength, long service life. Plates are widely used in private construction, industrial, for work inside and outside the premises.

When sheathing the frame, such plates serve as an excellent basis for cladding, decorative plaster, painting, as they form a perfectly flat and smooth surface. The material endures 50 cycles of complete freezing and thawing without loss of its characteristics; in the future, the strength of the plates decreases by about 10%. Among wood-based materials, DSP is the leader in terms of environmental and technical indicators.

Advantages:

very low hygroscopicity;
resistance to mold and other microorganisms;
DSPs are not damaged by insects and rodents;
the material does not emit toxic substances;
low thermal conductivity;
Fire safety.

Flaws:

mechanical processing of plates requires considerable effort;
DSP has a large weight compared to other materials;
when cutting and drilling plates, a lot of fine dust is formed, so you need to work in a respirator;
high price.

Fibreboard (Fibreboard)

The material is sheets of pressed shavings, usually softwood. During the pressing process, the raw material is strongly heated, which makes it possible to achieve maximum density without the use of adhesives. Due to this, fiberboard belongs to environmentally friendly materials, and therefore is suitable for outdoor use and for finishing residential premises. The shavings contain natural resin, which acts as an antiseptic and protects the plates from mold.

In terms of strength, fiberboard is noticeably inferior to natural lining and OSB, but it surpasses them in terms of heat and sound insulation properties.

Now in the construction market, fiberboards are represented by insulating boards of several well-known brands, the most popular of which are Beltermo and Izoplat. For sheathing a frame house, plates with a thickness of at least 25 mm are used, thinner sheets are used indoors.

Advantages:

light weight;
low thermal conductivity;
ease of installation;
the material does not exfoliate and does not crumble; high vapor permeability;
resistance to moisture and microbial attack;
the absence of harmful substances in the composition.

Flaws:

high price;
a long stay without a decorative finish causes slight deformation of the sheets;
the outer skin of fiberboard requires the presence of spacer braces in the frame or a rigid inner skin.

Gypsum fiber sheets (GVL)

In terms of frost resistance, soundproofing properties, as well as resistance to moisture and combustion, GVL is also several times higher than gypsum boards. Installation of GVL is carried out in a frame and frameless way. For external wall cladding, the first option is used, where the sheets are fastened to the bearing racks with self-tapping screws. The material is easy to cut and drill, and, despite its heavy weight, is quite easy to install. Such a sheathing serves as an excellent basis for finishing with tiles and decorative plaster.

Advantages:

low hygroscopicity;
vapor permeability;
the absence of toxic compounds in the composition;
fire safety;
high heat and sound insulation properties.

Flaws:

lack of plasticity and brittleness when bending the sheet;
great weight.

Plywood

Plywood is made by gluing thin sheets of veneer of various types of wood (most often coniferous and birch). Sheets are stacked perpendicular to each other relative to the location of the fibers, which increases the mechanical strength of the material and increases resistance to deformation. For the outer cladding of frame walls, plywood of increased moisture resistance is used, which is marked FSF. The thickness of the sheets should be from 9-10 mm, thinner material will not provide the necessary rigidity to the frame.

The grade of plywood does not really matter for sheathing, and the cheapest unsanded 4/4 grade boards can be used.

From the outside, all defects will be hidden under a hinged facade, so there is no point in overpaying. Subject to the sheathing technology, the plywood coating will serve for years without losing its qualities.

Advantages:

high flexural and compressive strength;
moisture resistance;
wear resistance;
ease of processing and installation;
frost resistance.

Flaws:

combustibility;
content of formaldehyde resins;
tendency to chipping.

Edged board

The use of edged boards for sheathing is the most economical option. Wood is an environmentally friendly material, affordable, easy to install. Boards can be filled not only horizontally, but also at an angle of 45-60 degrees. To save material, boards can be fastened in increments of up to 30 cm, although most often the sheathing is made solid. This design perfectly strengthens the frame and is a ready-made base for a ventilated facade.

In order for the sheathing to be reliable, the boards are chosen with a thickness of at least 25 mm, they can be tongue-and-groove, for greater docking density. Do not use raw lumber: in the process of drying, the wood will begin to warp, deformations of the finish coating may appear.

Advantages:

wood does not emit harmful substances and has excellent vapor permeability;
boards are easy to process;
work does not require large financial costs.

Flaws:

combustibility of the material;
wood is susceptible to damage by insects and microorganisms;
fitting and fixing elements takes a lot of time.

Cladding technology

Installation of plates on the finished frame is carried out according to the same technology, regardless of the type of material. Simultaneously with the cladding, vapor barrier and wall insulation are performed, and finishing can be done immediately upon completion of construction or after some time. Consider the installation technology using the example of frame sheathing with OSB boards.

Step 1.

Start trimming from the very corner. The first sheet of OSB is applied to the racks of the frame so that the lower edge completely overlaps the lower trim of the house. Be sure to control the horizontal level. The plate itself is also recommended to be placed horizontally, and not vertically - this provides the structure with greater rigidity. For fixing the material, galvanized self-tapping screws with a length of at least 50 mm are used. About 10 mm must be retreated from the edge of the OSB, the fastening step along the perimeter of the sheet is 15 cm, in the center - 30 cm.

Expert opinion

Filimonov Evgeny

Professional builder. 20 years of experience

Ask an expert

Advice. For strong fixation of the plates, the length of the hardware must exceed the thickness of the OSB by at least 2.5 times. If the self-tapping screw enters the frame beam by less than 30 mm, under the influence of loads, the sheathing will begin to break away from the supporting base.

Step 2

The next plate is installed next to the first, leaving a gap of 2-3 mm for thermal expansion. In the same way, they set the horizontal level, screw the sheathing to the frame guides. The joints of the plates must necessarily fall in the middle of the rack, only in this case the fastening will be as reliable as possible. The rest of the plates are fixed in a circle, leaving open areas for doorways.

Step 3

The second row of sheathing must be mounted with dressing of vertical seams. Between the lower and upper plates, the same gap of 2-3 mm is observed. When sheathing openings, whole sheets should be used, and not trimmings - the fewer joints, the tighter the sheathing. Cutouts in the sheets are made with an electric jigsaw or a circular saw, having previously marked out to the nearest millimeter. The edges of the cuts after the installation of the slab must ideally coincide with the lines of the openings.

Step 4

The top plates are installed so as to completely cover the top trim. If the house has two floors, the interfloor piping should be closed by the middle of the slab - in no case can the OSB be joined on this line.

Step 5

After completing the installation, a windproof membrane is attached over the skin. Her canvases are stretched horizontally and fixed with stapler staples to the OSB. At the joints, the film is overlapped and glued with adhesive tape. The material should not be pulled too tight, but there should be no sagging either.

Step 6

Next, the laths of the crate are stuffed for finishing in increments of 50-60 cm. The laths must first be treated with a protective compound and dried. After that, you can proceed with the installation of siding, lining or other decorative coating for the house. On a note! If it is planned to paint the facade from OSB, then the membrane, respectively, is mounted only on the inside of the house. With this method of sheathing, the insulation is placed on the inside of the walls into the cells of the frame and covered with a vapor barrier film. Slabs for interior decoration are sewn on top of the vapor barrier, for example, drywall or the same OSB.

Characteristics of materials for external cladding

And now let's bring specifications popular wall materials. With their help, you can choose the most suitable option outer wall cladding.

wood panels

When choosing wood sheathing, you need to pay attention to the following material characteristics:

Humidity - measured in%, it should be no more than 15%. The moisture content of wood determines its warping during operation.
Type of wood - determines the price and characteristics of water resistance, durability. The most expensive wood options are oak and larch. They are little susceptible to decay, while oak is very strong and durable. The most popular types of construction wood are pine and spruce, which combine the natural resinous nature of wood with an affordable price. Also there is a lining and a block house made of linden, alder, they are more suitable for cladding internal walls.
The shape or relief of the lining - can be flat, convex, concave, wavy. This characteristic is important for the decorativeness of the walls of buildings.
The type of lining is 1, 2 or 3 in the post-Soviet classification or A, B, and C in the European one. The grade determines the quality of wood - the presence of stains from knots, chips, hidden cracks.
The presence of external treatment - moisture resistant, antifungal or anti-fire impregnation.

Vinyl siding

Sheathing a frame house with siding often uses PVC plastic panels. This material has established itself as an affordable wall cladding with high decorative properties.

When choosing siding panels, the following characteristics should be considered:

The amount of recycled materials in plastic determines the quality, durability and price of PVC panels. Cheap panels contain up to 80% recycled plastic and are not suitable for exterior decoration. For outer cladding, it is allowed to use panels, in the lower layer of which there is no more than 5% of raw materials.
The content of modifiers - determines the strength of the panel and its price.
The content of other chemical compounds: butadion - no more than 1%, titanium dioxide - no more than 10%, calcium carbonate - no more than 15%.
Panel relief - determines what kind of walls the vinyl siding will imitate.

How cheap to sheathe a frame house

The cladding of the OSB frame house outside has gained popularity primarily due to the very affordable price. At the same time, they try to compensate for the shortcomings of OSB, their low moisture resistance and insufficient strength, with additional protection of their surface, plaster or painting.

The choice of panels for sheathing an OSB frame house should take into account the category of building material. The category of plates is indicated by numbers - 1, 2, 3 or 4. It determines the purpose and technical characteristics - strength, moisture resistance, the possibility of using it in outdoor construction. for sheathing frame wall plates of category 3 or 4 are required.

And now let's talk about how to properly sheathe a frame house.

Features of installation of a ventilated facade

The exterior finish of a frame house is often arranged according to the type of ventilated facade. Especially if a cotton insulator was used to insulate the walls - mineral wool or glass wool. This insulating material requires a ventilation gap between its surface and the wall sheathing. How to sheathe a frame house with OSB, board or siding?

During the construction of a frame house for siding, a so-called crate is constructed to equip the gap between the insulation and the wall sheathing. It is a wooden or metal plank that is attached to the frame supports. Wall cladding is mounted on top of the planks. Thus, the outer panels are located not close to the heat insulator, but at some distance from it.

In order to increase the strength of the installation of wall sheathing, the low-strength crate is replaced with wide frame racks. Their thickness should be greater than the thickness of the insulation, then between the surface of the heat insulator and the outer edge of the frame support, after hanging the panels of the outer wall, the necessary gap will be formed. This is done to sheathe a frame house outside the OSB.

Existence of a vent gap provides protection of external panels from moisture. Therefore, such a gap is absolutely necessary when building a frame house with an imitation of a bar, “under a tree”. Or when using wood chip boards. In the absence of air space, steam particles will collect in the outer wall, causing dampness, rotting, and fungus.

Exterior decoration of a frame house - is it really necessary?

A modern cottage is a wooden structure built on the principle of a skeleton, on which walls, ceiling, roof and floor are attached. Its versatile design allows for a wide range of cladding choices. The tree itself is not ideal: in order for the heat not to escape through such walls, it is necessary to bring their thickness to 6 centimeters. If metal is used for the base, then the problem of heat loss is even more aggravated. Properly choosing the material for decoration, you will provide yourself and your loved ones with comfort and health. The house will be reliably protected from wind, frost, precipitation and high temperatures.

When choosing an option, pay attention to the following information:

Modern frame houses are lined with materials that can take on part of the load. They give the structure additional rigidity. The main criterion for selection is the mechanical strength in compression and bending, the absence of shrinkage.
The exterior finish must repel moisture, be resistant to temperature extremes and the effects of microorganisms - fungus and mold.
The pliability of the material during processing and the ease of its installation are important. Especially if you decide to do everything yourself. The total repair time depends on how easy the installation will be. The selected building material should be amenable to drilling, cutting, while maintaining the cut density, should not crack, crumble.
The material must be durable. This includes saving money, time and effort. You will not have problems with the cladding if it lasts for several decades and does not lose its original appearance.

If the frame house is located in the middle lane, where in winter very coldy, and in the summer it is hot, it needs to be sheathed from the outside very high quality.

Brick and facade board - a classic for all time

Natural brick block is a material that is traditional in the field of sheathing frame houses. The brick is durable, perfectly retains heat and does not let the cold through, durable.

With proper masonry, the finish looks attractive, it does not need to be painted or treated with special compounds against moisture, fire or mold. During work, it is necessary to leave a gap between the surface of the building and brickwork. Otherwise, condensation will accumulate inside.

In order to lay a brick beautifully and correctly, skill is needed. This finish option has an average cost.

Another disadvantage is that it is not possible to choose an interesting color or texture, as is the case with siding, clinker tiles or artificial stone.

If you like eco-friendly, natural materials and want to save money at the same time, choose a facade board that imitates timber. The material has two sides. With the planed part, it is attached to the wall, and the polished part is outside. The board is sanded so that the paint is better absorbed into it.

There is already painted material on the market - you just have to choose the right color.

Before decorating a house, read carefully the descriptions of today's popular materials, take the time to visit the store, which has a large selection for builders. "Live" acquaintance with different options help you choose what's best for you!

Finishes

The exterior finish of a frame house can be made of various materials, so when choosing a certain type of product, it is worth learning about their features. Some materials can be fixed on your own, while others will have to hire professional builders to install.

In order for the exterior decoration of a frame house to be admired, it is necessary to choose the right finishing materials that are suitable for the design style you have chosen.

It is impossible to leave a frame house without finishing, so you will have to choose the material in any case.

The most common include:

Hanging structures. Thanks to such products, it is possible to additionally insulate the building from the outside if it is located in a region with a continental climate. When choosing this method of finishing, you can use metal, brick, stone and other materials.
Plaster. Such compositions may various shades, so if you wish, you can decorate the house in any style.
Front brick. When choosing this material, it should be borne in mind that the weight of the house increases significantly. That is why it is worth choosing the material for the external design of the building at the design stage.
Siding. This material is characterized by low cost and a sufficiently long service life.
PVC panels. Such products can imitate bricks, boards and other materials. If the exterior finish of the frame house is made with my own hands, it is necessary to constantly check the location of each element of the skin.
Panels based on polyurethane. This material allows not only to change the appearance of the building, but also to insulate the facade.
Facade tiles. This material is fixed with glue or with the help of special fasteners for tiles.
Block house. The specified sheathing material is created on the basis of wood and gives the houses a natural look.

When choosing any material, it is important to purchase only reliable products. Sheathing of the house must be done correctly without cracks and gaps. It is best to entrust the work to professional builders. In this case, the finishing of the frame house from the outside will be done with high quality and in a shorter time than when creating the cladding with your own hands.

Mounted structures

Hinged finishing structures have many advantages over other types of similar materials. If desired, you can completely change the appearance of the house by fixing the appropriate panels. The frame for fixing finishing materials is most often created from metal. At the same time, a space is set aside between the finish and the wall in which insulation can be placed. Usually mineral wool is used.

It should be noted that the use hinged structures allows you to improve the sound insulation of the structure, making the house more comfortable. The described structures can be divided into ventilated and non-ventilated. Products of the second type are fixed easier, so many owners of country houses choose them. It is also important to take into account that interior decoration frame house should be combined with the selected material.

Wet cladding

Most often, the wet cladding of a wooden house is produced with additional insulation. For this, foam boards are used. At the time of purchase, you only need to choose plates for exterior decoration. Such foam is called facade and has the letter f in the marking.

Extruded polystyrene foam should only be used to insulate the basement of the building. This is due to the fact that such material is more rigid and does not absorb moisture. Styrofoam gluing occurs joint to joint. In order for the primer to fix on the surface more reliably, it is necessary to process the plates with sandpaper.

After fixing the foam, a special glue is applied to its surface, into which a fiberglass mesh is embedded. After that, the surface is covered with a quartz primer. This composition contains sand filler. Only after carrying out the described work can the plaster be applied.

Compositions for finishing the facade of a frame house are divided into acrylic, silicone, mineral and silicate.

facade brick

The described material can be divided by composition and shade. For exterior decoration, such types of this material are most often used, such as:

silicate brick;
ceramic;
hyperpressed.

Silicate brick is of low cost, and ceramic is more beautiful material. Bricks are divided into solid and hollow. Products of the second type retain heat better. That is why they are chosen by many owners of frame buildings.

It is not worth laying this material in winter, since at sub-zero temperatures the solution freezes and the masonry becomes more fragile. Before finishing works needs to be accurately calculated. right amount material.

Brick batches can have a different shade, which will negatively affect the appearance of the building. To make the color of the masonry more uniform, you can treat the walls with 10% sulfuric acid.

If the exterior finishes are done correctly, the house will look like a building built entirely of bricks. It is also important to choose a shade roofing material to match the color of the brick.

Thermal panels with clinker tiles

For sheathing a frame house, many use thermal panels. They not only decorate the wall, but also contribute to the preservation of heat in the house. Panels are fixed seamlessly. Many owners of suburban areas choose clinker tiles to decorate a frame house, as it is not subject to abrasion and mold deformation.

Fixing the material on the walls is as follows:

First, the geometry of the structure is reconciled. All walls of the house should be perfectly flat, and the corners should be 90 degrees. If there is even a slight deviation, it is necessary to create a crate for the entire structure.
Installation of the base profile. At this stage, the aluminum profile is fixed in the horizontal direction. During the work it is necessary to use the building level.
After that, the corner thermal panels are fixed.
At the next stage, the panels are installed over the entire area of \u200b\u200bthe facade. For this, dowels or self-tapping screws are used.
Then you need to seal the panels, filling the gaps between the panels. Seams are treated with grout, which is resistant to low temperatures.

Choosing this method of finishing, you need to be prepared to spend a lot of money, since the material is very expensive. You will also have to spend money on the services of builders.

Using tiles for brick, stone and other materials

When using tiles, you can not only modify the structure, but also protect it from external factors. Fastening should be carried out on the crate in such a way that there is a gap between the finishing material and the wall. It is important to press the tiles tightly against each other, since even a small gap can cause moisture to get through the tiles onto the wooden walls. The tiles are fixed with glue.

The described material has the following advantages:

A wide variety of shapes and colors. Thanks to this, if desired, you can decorate your own frame house in an original way.
Ease of installation. Even if you hire professional builders, the cost of the work will not be high, since the fixing of the tiles occurs quickly enough.
The lightness of the tiles. Since the material is light in weight, strengthening the foundation of the house is not required.
Wall protection frame house from moisture and condensation.
Environmental friendliness.
Attractive appearance. Tiles allow you to create a design that is difficult to distinguish from finishing with expensive varieties of stone.

When deformations appear, the tiles are easy to replace. To do this, you just need to remove the damaged products, fixing new ones in their place.

Using a block house

If you want to decorate the building as a house made of timber, you should use a block house. This material is a part of rounded logs with a flat surface. It is with this side that the material is fixed on the wall, so that after finishing work it seems that the house is built of logs.

In addition, the block house has other advantages:

Environmental protection. The material is coated with special compounds that allow you to extend the life of the wood.
The ability to insulate and fix soundproof material. Mineral wool is often placed under the finish.
Fixing the described products can be done by hand. It is not necessary to hire professional builders to carry out the work. But it should be remembered that in order to eliminate errors, it is important to work with an assistant.
The possibility of replacing each element of the frame house decoration.

The structure and features of the framework

Do-it-yourself interior decoration of a frame house, as well as exterior decoration, should be carried out taking into account the structural features of this type of structure.

The following differences most noticeably affect the finish:

The load-bearing basis of the house is a wooden frame, which distributes the load through a system of racks, beams, rafters and crossbars from the roof of the structure to its foundation. As you know, the tree is quite flexible and soft material, and under the action of forces, the frame shrinks somewhat, there is an uneven displacement and movement of parts relative to each other;
As a rule, skeletons are placed on columnar or pile foundations, and uneven subsidence of the structure is possible, which is not particularly fatal for the frame, since it is flexible and can allow slight distortions and changes in geometry, but a monolithic coating, such as plaster, may crack;
The walls of the house consist of a system of frame beams and panels that fill the space between the beams. Often, instead of panels, this space is filled with insulation and sheathed on both sides with moisture-resistant OSB plywood, which in itself cannot serve as a facade finish either in terms of decorative or structural characteristics;
The structure of the wall is such that the insulation is located in its inner space, therefore, for middle lane and south external insulation not required. At the same time, many people still sheathe houses with polystyrene foam, as it is an excellent basis for plastering.

All these features allow you to determine how to finish the frame house from the outside, so that the coating lasts as long and efficiently as possible. As a rule, preference is given to hinged facade structures, various panels and slabs, wood paneling and plaster.

Important! Facade decoration with facing bricks is very rare, since a frame house is a variant of budget prefabricated housing, and the price of laying work and the cost of the brick itself make this advantage insignificant.

Surface preparation for painting

In order for the paint to lie well on the surface of the sheathing boards, it is necessary to process the entire surface with a grinder, while the grinder must be filled with sandpaper (grain gradation of sandpaper for grinders 25, 40, 80,120) I used with a grain of 40.
If we plan to paint the facade of the house with oil paint, then we first apply two layers of drying oil to the surface of the skin, after it dries, we proceed to painting the house.
The surface of the sheathing can be painted with a wide brush, roller or using an airbrush.

Finishing window openings

Plastic corner for the decorative appearance of the ends of the siding panels in the window opening

In order to hide the ends of the siding panels at the window openings, I used a plastic corner instead of wooden trim.
I fixed one side of the corner on the front side of the panels, and the other side hid the ends of these panels. The corner was installed in such a way that it fits snugly against the window opening with one end.

Note: Siding panels can be trimmed with a saw blade, or with a electric jigsaw with a file having a small tooth.

Important! Sheathing the walls of the house with siding should be done in the warm season. Since at a temperature of + 15 degrees, siding panels have better ductility than at low temperatures.

Also, do not pull the panel up strongly when installing it, since when sub-zero temperatures, the siding will shrink even if it is strongly stretched at the time of installation - the panel may simply crack.

Installation and insulation of the cladding

All materials used for sheathing a frame house, with the exception of boards, are sheet. Therefore, special difficulties with installation usually do not arise. To fasten the sheets to the base of the frame, nails with a wide hat of a suitable size are used. However, the length of the nails must be at least 70-80 mm.

Since some of the materials are more fragile, they can be fastened using screws - when screwed in, they do not leave cracks and do not split the plate.

You can mount the plates depending on the size of the wall and the size of the perimeter. Their arrangement can be vertical or horizontal - this allows, depending on the situation, to more economically use the remaining material after cutting.

In order to enhance the insulating qualities of the sheathing material and to give an even greater degree of heat capacity to the structure itself, it is necessary to lay heat-insulating materials under the sheets of sheathing material. The building materials market at the present time produces enough products with such qualities.

Thermal insulation materials can be roll type or in the form of small plates.

For this purpose, under the skin, you can mount:

Styrofoam sheets. Depending on the sheathing material, the thickness of this insulation should be from 50 mm and above
Styrofoam- the material is even more efficient than the previous version due to its high density. However, its cost is much higher. In sheathing works, a thickness of expanded polystyrene from 30 mm is used
Mineral wool- roll type of materials. It has excellent insulating properties. But due to the peculiarities of rolled products, this material is characterized by a higher labor intensity during installation.

Along with these classic materials, their modern counterparts can be used. In most cases, laying insulating materials and the installation of cladding materials, the procedure is completed.

However, in some cases, additional processing of the outer surface of the sheathing with soil mixtures is carried out to give them greater technological characteristics, counteract external environment and strengthening the outer layer of the plates.

Based on materials from the site: megabeaver.ru, fasad-exp.ru, 1karkasnydom.ru, obustroen.ru, bouw.ru, nashaotdelka.ru

A frame house is popularly called a panel house, but such elements are not used when assembling the structure. Any frame house needs additional cladding. For this, different materials are used. Building materials that are used in outdoor installation work must have a number of characteristics and requirements regarding product quality. If we are talking about a new frame house, you should take care of high-quality external cladding before proceeding with internal facing work. The facade of the house is then decorated with moisture-resistant materials.

Sheathing is able to increase the rigidity of the building frame by distributing the load on itself. The main indicators and criteria by which the facing material will be selected will be the strength and absence of bending during compression of the panels. During operation, shrinkage should be avoided. The surface and structure of the walls should remain unchanged after years, regardless of external factors and climatic conditions of the region. The material used must be resistant to moisture, pests, fungi and significant temperature changes.

Difficulties in the planned installation can arise at any stage, and they will consist in the intricacies of the upcoming manipulations, and not depend on the weight and dimensions of the material used. Provided that the upcoming work is planned to be carried out independently, the complexity of the work will play a paramount role, since hiring assistants is not expected. The building material used should be easy to drill and cut, while not crumbling and retaining its original performance. Replacing such a skin every few years is an expensive undertaking.

Materials such as:

edged board;
OSB (OSB);
moisture resistant types of plywood.

According to the characteristics, the materials are similar and are used in the construction of frame structures. In order to commit right choice, you should familiarize yourself with all possible options in advance.

The main thing about OSB (OSB)

A material such as OSB (oriented strand board) is considered the most popular among modern building materials, largely due to its versatility and the possibility of being used in the construction of frame structures. They are structures consisting of several layers of pressed wood chips and shavings. The inner layers are laid transversely, while the outer layers are laid longitudinally. As a connecting material, wax and resins of synthetic origin are used, which have the characteristics inherent in water-repellent impregnations.

When pouring concrete structures, based on the ratio of cost and quality of the material, preference is given to OSB-3, which is widely used in private construction and in finishing works of various levels of complexity. OSB is applied:

creation of reusable formwork;
load-bearing partitions;
wall cladding.

The surface of the plates is able to tightly hold nails (0.7 cm from the edges), lends itself to drilling, cutting, grinding. In addition to a technical purpose, the lining serves as a decorative coating. To do this, the surface is treated with paint or moisture-resistant varnish.

The disadvantages include:

the content of formaldehyde and phenol - toxic compounds;
combustibility;
low vapor permeability.

Installation of vapor barrier and OSB (OSB) boards

In order to prevent moisture from penetrating the insulation layer, the material is protected. The walls on the outside of the frame building are covered with a vapor barrier film. A construction stapler is useful as fasteners. The roll is rolled into horizontal strips, which are fastened with an overlap (5-10 cm) to the racks located vertically. The film should adhere tightly to the surface, which should be checked. After the vapor barrier layer is covered with OSB boards, which act as a base for subsequent finishing. As fasteners, a screwdriver and standard self-tapping screws are used. The panels are fastened alternately, a jigsaw is used for cutting.

Insulation installation

An example is the use of such a heater as mineral wool, which is attached to the frame slabs. Such a material is characterized as elastic, an auxiliary method of fastening is not required, which allows you to place a heater between the racks. The material will be held due to its own size. The insulation is laid in two layers in a checkerboard pattern. Butt joints of the first layer will be overlapped by the second strictly in the center. Thus, it is possible to avoid the formation of cold bridges in the future, which cause the formation of condensate and dampness in the premises. As a result, fungus and mold will not have to wait.

After completion of installation work, the installed plates should be protected from strong gusts of wind, rain and snow. Sheathing of the material is carried out using the same technology that is applicable for internal walls. It will be necessary to equip a windproof and waterproof membrane that will protect the surface of the walls from wind and bad weather. For greater reliability, the membrane is fixed by means of a counter-batten.

Paneling exterior walls

When carrying out external finishing work, OSB sheets with a thickness of 1.1 cm should be used. In the process of carrying out work, the following recommendations should be followed:

In order to sheathe window and door openings, one should use solid sheets, inside of which the corresponding openings are then made.
When arranging a two-story building, sheets should be installed in such a way that both floors overlap simultaneously. This will help to give the frame the necessary rigidity.
The junction of one of the sheets should fall on the central part of the other. Thus, the frame will acquire the necessary rigidity.
The gap between the panels will be 0.5 cm. Due to frequent temperature changes and humidity, the dimensions wooden structures may change and this will require extra space.
Every 10-15 cm, the plate is fixed, 20-30 cm in the center. To avoid splitting the material, indents of 1.5-2 cm are made from the edge.
A small space is left between the panel and the waterproofing layers so that ventilation is present.
Nails are used to fasten OSB sheets. Suitable for both screw and ring galvanized. The length of the element will be 3-4 times the thickness of the sheet used.
Panels are mounted matte side inside. One plate must be in contact with three racks of the frame at the same time, to give the structure rigidity.

Any facing material can be used for processing plates. The use of OSB sheets is considered an acceptable solution when comparing quality and cost.

We sheathe a wooden frame with OSB boards

Recommendations regarding the material used for sheathing frame structures, are similar to those applicable to already erected walls. However, in this case, the sheets will be considered the key or main stiffener. The thickness of the sheet will be 1.2 cm or more. It is recommended to give preference to 1.5-1.8 cm of thickness. Two approaches can be used: fastening OSB sheets without the use of a crate and assembling the frame with the participation of the crate.

Without crate

When considering methods that would provide structures with the necessary stiffness index, only three are considered optimal. They can be combined with each other:

Sheet material is attached to the racks on the outside of the building;
Arrangement of jibs between the racks of the frame;
The material is fastened inside the house to the racks.

In the process of mounting the material to the outer racks of the frame, the presence of the crate reduces the stiffness index by half. To increase the indicator, the crate will be excluded. The absence of a crate indicates violations of the ventilation (gap), which makes it necessary to fix such a structure on top of the installed OSB sheets. On top of the sheets, wind and hydro protection in the form of a vapor-tight film is mounted, after the crate and the selected facade finishing material. Facade panels, wood, corrugated board or siding act as such. When using the Finnish technology for the construction of buildings on the "platform", there will be no crate between the OSB sheets and the frame.

This option is considered to be the most preferable, but other methods are applicable. If the OSB sheets will act as a facade design, and nothing is planned to be mounted on top of them, then the ventilation gap is arranged between the racks of the frame itself. To do this, the space will not be completely filled with insulation. For a ventilation gap, a space of 2-3 cm is enough. Reiki will be needed to fix the vapor barrier film. This should be done in such a way that the rails are on both sides of the racks.

As a compromise, another option is possible when an oblique crate is used. The laying of the material is carried out at an angle of 45 °, which leads to an increase in the rigidity index, compared with the direct version of the crate. To improve the stiffness index, boards with a diameter of 2.5 cm should be used. Fastening is carried out to each of the frame racks using two nails. The method is used extremely rarely due to the high complexity of the upcoming work and the high cost of materials.

Using the crate

In the case when strong plates are attached to the frame, which are responsible for the increased strength of the structure, a crate is mounted between the OSB and the frame. Thus, a ventilation gap is provided, which is necessary for ventilation of the insulating material and reducing the deformation rate of the load on the slab from the frame. The heater is mounted between racks. Insulating material is laid on top of them, waterproofing and wind insulation are fixed in the form of a membrane that is able to pass moisture. After that comes the turn of the battens and OSB boards.

Thus, savings are possible in the form of the absence of the need for subsequent finishing work. The surface of the plates should be painted or varnished. If desired, after that, any facade material can be attached to the surface of the OSB boards. Fastening the OSB in the absence of a crate will allow achieving the maximum allowable indicator of structural rigidity. So, hydroprotection and wind protection will be behind the slab, after which a crate is installed, which will provide a ventilation gap to the wall. On top, if necessary, you can use facade material in the form of decorative panels, boards, siding. The plates are attached to the frame with nails, the length of which should exceed the diameter of the OSB several times. Nails should be used as fasteners, not self-tapping screws, which better tolerate possible deformations of sheets in the future. Self-tapping screws will not survive such changes.

Using a metal frame

The upcoming manipulations will be the same as in the case of the wooden frame option. Self-tapping screws will act as a fastener, the length of which should exceed the dimensions of the sheet by several centimeters.

Rules to follow

Regardless of which of the methods for fastening OSB sheets would not be chosen, there are a number of recommendations that will help ensure the maximum allowable indicator of structural strength, and ensure a high operational life of the building and the material used.

To make holes for door and window openings, use a circular saw or a jigsaw. To obtain even cuts and joints, you should contact the furniture production workshops, having carried out the necessary measurements in advance. For a reasonable fee, specialists will do the necessary manipulations accurately and in the shortest possible time.
Close to each other OSB boards are not joined. A gap of several millimeters should be left so that the subsequently expanded plate does not deform.
A gap of a centimeter is made between the foundation and the bottom plate, which will eliminate the accumulation of excess moisture.
Self-tapping screws are mounted at a distance of 10-15 cm from each other. An indent of a centimeter is made from the edge of the plate.

OSB protection against insects, birds and mice

Almost any of the existing methods for installing OSB boards provides for the arrangement of a gap for ventilation. Thanks to a small air gap, an influx of air will be provided, which will flow from the lower edge of the wall from the environment and rush back into the atmosphere through the top. It is unacceptable to make the gap deaf, which will nullify the efforts and costs. A closed air cavity will not perform the intended functions. Birds, mice and bees penetrate into such places, thereby reducing the initial characteristics of the wall surface. Protection from such visitors is essential and should be planned for during the first phase of construction or renovation.

Protection against rodents can be carried out in this way:

The use of perforated facade material in the upper and lower parts of the wall. Soffit, which is used in combination with siding, can act as such.
The grid is painting. The cost of the material is acceptable, the strength index is low (rodents will cope quickly).
Installation metal meshes based on sheet material, in which small holes are made in large numbers. Stainless steel works best, as it will not corrode over time due to excessive moisture. Strips or mesh made of metal are attached to the upper and lower parts of the wall immediately behind the OSB sheets, which will not affect the appearance of the building.

Video consultation on the installation of OSB panels:

OSB application

OSB in a frame house is attached outside the building to the frame racks. The construction project is drawn up for this material. The dimensions of the panels should be taken into account so that the OSB on the walls of the frame house is fastened with joints on the frame racks. Masters of frame construction must take this moment into account.

The building is sheathed with OSB from the inside.

Thanks to this construction technology, the panels are securely connected to the base of the building. The design of any frame house involves the use of materials of different sizes, so the slabs will still have to be cut. The task of the professional drafting the project is to ensure that such manipulations with building material was less.

Openings and other holes are made on the plate with the help of a special tool. Construction tape is fixed at the joints of the plates. Such manipulation is carried out to seal the walls. This has a positive effect on the indoor climate. Thanks to the sealing, the frame house sheathed with OSB has a long operational period.

On a note

Even if a frame house is being built without OSB, there must be sheathing, and you can use plywood, chipboard, DSP, isoplat.

Types of OSB

There are the following types of OSB panels.

OSB - 1. These are plates of low mechanical strength. They are used only for structures that do not carry a load-bearing load. They include . The panels are also used for wall cladding in a dry room.
OSB - 2. Such material can be used inside dry rooms for finishing walls or ceilings.
OSB - 3. The panels are used in rooms with high humidity.
OSB - 4. They have an increased mechanical strength. Approved for use inside and outside the building.

In a frame house, OSB 3 and 4 are used.

Comparison with plywood and DSP

Is it possible with panels - the actual question of users who build this type of structure. Professionals advise using this product for building decoration, as it has a number of advantages over other similar products.

Dimensions of OSB board - 2 and OSB board - 3.

Plywood

OSB and plywood have similar characteristics, but there are differences between the materials. The main difference between the products is the method of manufacture. For OSB, wood chips are used, and plywood is made from several layers of veneer. This makes panels a cheaper building material.

For this reason, the finishing of the OSB frame house is performed more often. According to the characteristics, this product is inferior to plywood. It is not as durable and moisture resistant, so it wears out faster, especially in harsh climates.

Cement particle board

OSB has General characteristics and with the CSP. Such building materials are in the same price range. However, OSB is inferior in some respects. DSP is an environmentally friendly and fireproof material that is resistant to negative environmental manifestations and has increased mechanical strength.

Cement particle board.

The disadvantage of the product is a lot of weight. OSB board is several times lighter than such material. DSP is inferior to OSB also in that defects can occur on them during tilting and fastening of such panels. For these reasons, OSB frame houses are most often trimmed with panels, since the material has a light weight, affordable price and good performance.

OSB outside

If the external sheathing of the OSB frame house is performed with a slab, then you need to take care of the finishing in advance. Usually, siding is used for this or plastering is performed with preliminary reinforcement and insulation.

OSB sheathing

Building sheathing algorithm:

The panels are mounted on the frame in such a way that the joint of the plates is located in the center, and the gap between the sheets is 3-5 mm;
Sheets of material are attached around the entire perimeter and capture the bottom trim, the edge of the strap is aligned with the edge of the material;
For a multi-storey building, the slab is placed so that it captures two floors at once, while the middle of the panel should overlap the upper trim;
Window and door openings are cut from a single plate.

Pie frame wall with OSB.

To fasten the material, spiral nails or self-tapping screws are used, and both fasteners are combined. To ensure the sealing of the structure, a sealant made on the basis of acrylic resins is used. They process all docking seams and other cracks and gaps.

The frame house cake with OSB is made using waterproof and windproof materials. A superdiffuse membrane is suitable for this. This design of the wall will create a comfortable microclimate for living inside the room.

The pie of the frame house with OSB on the outside should not contain glassine and films. These materials have low vapor permeability, which creates favorable conditions for the vigorous activity of an aggressive biological environment.

If the frame house is insulated with OSB panels without using additional materials, then inside the building it will be cool in severe frosts even with good heating. For this reason, it is not recommended to ignore the use of heat-shielding products.

Sheathing order

If we talk about how to properly sheathe an OSB frame house, then the finish is as follows:

Panels are attached to the base;
A vapor barrier layer is laid;
Insulation is attached;
Another layer of vapor barrier film is laid;
The pie is closed with panels and an external finish is performed.

As an alternative to decorative materials, experts suggest using OSB boards for exterior finishing according to the wet facade system, which involves the use of plaster to level the building base.

Wet facade finishing

The algorithm of work in this case will be as follows:

Thermal insulation material is fixed on the panels. Mineral wool or polystyrene can be used as such a product.
Install reinforcing mesh. Such material increases the adhesion of insulation and plaster. The mesh allows you to apply the product even in a thick layer.
Apply a layer of starting plaster. It allows you to hide surface imperfections and level the building base.
Perform finishing work. For this, it is recommended to use decorative plaster. You can pick up material with different textures that create original textures on the surface - “fur coat”, “bark beetle” and others.
If used for decoration white plaster, then it can be painted. To do this, use a paintwork material of any shade.

Wet facade on OSB.

By doing wet facade it is important to remember that materials are applied only after the previous layer has dried. If the OSB frame house is lined on the outside with high quality, then the building’s operational period increases without losing its external attractiveness.

OSB inside

OSB boards inside the frame house are also used. The material increases the sound and heat insulation of the building.

How to work with OSB

Insulation is fixed on the walls. In this case, it is recommended to use mineral wool. It is securely fixed in vertical position and doesn't roll down.
Walls are being vapor-proofed. To do this, a vapor barrier film is fixed on top of the insulation. It will protect the building base from moisture, thereby extending the operational period of the building. A construction stapler is used to fix the material. The film is fixed overlapping each other by 10-15 cm. The joints are glued together using masking tape.
Attached OSB boards. After that, decoration is carried out. Since the board has an uneven surface, it is recommended to choose a finish that hides these imperfections. If, for example, the panels are painted, then all the flaws will be visible, which will negatively affect the appearance of the finish.

OSB panels are not always used only for rough work. Their original texture is attractive in itself, so the plates are also used as a decorative material indoors, as shown in many video tutorials.

OSB panels for finishing

First of all, the crate is performed. To do this, rails are attached to the sides of the walls, as well as on the ceiling and the field. Further, the profiles are fixed around the entire perimeter. They are fastened in such a way that the joint of the panels falls exactly on the rail. The profiles are mounted using the rule so that after fixing the plates, the surface is smooth without blisters and depressions.

Panels are fixed to the profiles. Self-tapping screws are used for their installation. The plates are fastened with a small gap of 3 mm. To increase the attractiveness of the material, you can cover it with a transparent varnish.

Pros and cons of OSB

Sheathing OSB frame house has the following advantages:

The material has a dense structure, so the panel does not deform during operation and processing;
Plates have increased mechanical strength;
The panels are resistant to negative influence environment;
The material is resistant to the action of an aggressive biological environment, so the fungus and mold on the OSB on the walls of the frame house do not occur.

Cons of OSB panels

Poor vapor permeability of OSB, however, the vapor permeability of OSB 3 is less than that of plywood, which is why professional craftsmen prefer panels;
Flammability, which makes the material a fire hazard;
Harmful substances are used in the production chemical compounds, however, recently, manufacturers have been using only formaldehyde resins that do not harm human health, so this disadvantage is relevant only for a low-quality product.

OSB slab in a frame house is a quality and reliable material With good term validity. Like all similar products, the panels have their drawbacks, which are offset by an acceptable cost. Even a non-professional can build a building using this material.

The panels are light weight and easy to mount on the surface. However, for quality construction buildings are best left to professionals. The services of craftsmen are relatively inexpensive, but they will build a frame house in a short time and provide a guarantee for their work.
