What are sip panels. SIP panels: reviews of residents, pros and cons, material characteristics. Wall building tricks
When looking for ready-made frame and energy-efficient solutions for building a house, more and more information is found about the use of SIP panels for quick and less expensive construction of buildings. Advertising is full of statements that houses made of SIP panels are more cost-effective and at the same time they are superior to standard brick and concrete solutions. Is it so? It is worth considering in more detail.
What is a SIP panel and why is it needed?
This interesting and versatile material is used in construction during the construction of frame structures. In fact, SIP is a structural insulating panel, consisting of a layer of insulation, covered on both sides with OSB sheets. The layers are interconnected with the help of polyurethane glue, with an external impact of the press with a pressure of 18 tons. Oriented strand board consists of several layers of wood chips that are bonded together with resins. This material is gradually replacing the usual chipboard due to its strength and some degree of elasticity. Foamed plastic, better known as expanded polystyrene, is used as a heater. Due to the fact that it is easy to manufacture and conducts heat poorly, this material is an excellent insulator.
Houses built using this technology are often called "Canadian", because it is from the harsh climate of Canada that this method came to our market. Despite the fact that this method of rapid construction is already several decades old, it is still perceived with hostility. It is worth noting that people tend to distrust, especially to such a seemingly fragile material. Brick is still a priority choice in the eyes of many consumers, despite the fact that it is by no means an ideal and has a number of disadvantages. While we still have a strong distrust of SIP panels, practical Americans and Europeans create entire associations that help beginners in word and deed, and in addition are able to give practical recommendations on construction. SIP panels, the photos of which illustrate their simplicity well, will be an excellent choice if you want to build a house quickly and at no extra cost.
Main advantages and disadvantages
Of course, any technology has both its advantages and disadvantages. The main advantages are in the areas of convenience and the resulting comfort. SIP panel projects will be a smart choice, as the buildings under construction have the following advantages:
- Thermal insulation of plates. Canadian houses are distinguished by the best degree of thermal insulation, in comparison with which the brick noticeably gives in. According to experts, to achieve the same low loss factor for bricks, a wall thickness of at least 2.5 m would be required, while the standard panel thickness is 17 cm.
- Excellent soundproofing. Despite the thickness of the panel, the expanded polystyrene well prevents the penetration of noise from the street.
- Light weight overall design. 1 m2 of panel has an average weight of 15-20 kg depending on the thickness. For example, a similar area of brickwork is quite capable of exceeding half a ton. This leads to the following advantage: houses made of SIP panels do not need a powerful and expensive foundation; for the Canadian type, a shallow-depth strip foundation is sufficient.
- Short construction time. Structures from SIP panels are built in a matter of weeks. For example, a two-story country cottage with a total area of 50 m2 is built on a turnkey basis in 3 weeks.
- Construction can be carried out at any time of the year, according to this criterion, SIP panels have no restrictions.
- Due to the low weight of the panels, they are easy to transport and unload, which allows you to significantly save on delivery and loader services.
- The panels are resistant to aggressive external environments, including biological ones. For example, such as mold or fungus.
- SIP panels, the price of which starts from $25 per m2, will be an excellent alternative to other building materials both in terms of cost and ease of construction.
- Due to environmental friendliness and health safety, SIP panels are used for installation in any type of building, they do not leave behind construction debris and do not emit allergenic substances.
- Ease of panel installation. They do not require special skills or equipment. Any work, from the construction of a small extension to the construction of a cottage on several floors, in fact, requires only the presence of the panels themselves, self-tapping screws, mounting foam and a set of basic simple tools.
Tests have shown that SIP panels have significant mechanical strength, which can withstand longitudinal and transverse loads well. Values of 10 tons per m2 for longitudinal and 2 tons for transverse floors are a convincing factor.
The list of advantages of SIP panels is quite convincing. However, it also has some drawbacks, sometimes overly “inflated” by adherents of brick and concrete:
- flammability
- environmental hazard,
- rodent resistance.
Many buyers are primarily concerned about the fire resistance of SIP panels, since OSB boards are 90% wood. However, there is no reason to worry, since they are treated with a special agent called a fire retardant. As a result of its use, the fire resistance of the board increases up to 7 times compared to ordinary wood. The expanded polystyrene used in such panels has self-extinguishing properties, therefore, even when exposed to an open flame on the material, the flame does not spread to neighboring structures.
From the point of view of environmental friendliness, the material does not pose a danger to humans. Adhesive components certainly emit harmful volatile compounds into the atmosphere, but their amount is not capable of harming health.
Now it is important to consider the problem with rodents. As you know, they are able to penetrate the home in different ways. There is a concern that polystyrene foam will become a favorable environment for the penetration of rodents. However, no such problem was noticed due to the fact that the insulation material is closed on both sides with boards and OSB boards. Resin-impregnated chips are a good barrier against pests, as this material has sufficient strength. The insulation is inedible and for this reason is of no interest to rodents.
In the event that SIP panels are used for the construction of buildings not according to the "Canadian" technology, but as building materials for sheathing frame structures, it is worth remembering that some other disadvantages will also appear:
- Drafts are often observed at the joints. This disadvantage is easily eliminated with a mounting tape and is irrelevant for "Canadian" houses.
- In the absence of insulation, individual sections begin to freeze through.
- Condensation accumulates at the joints of the plates and the frame, which will lead to the appearance of joint defects.
- There is a possibility of cosmetic damage to the slab during careless transportation or cutting. In this case, you will need to cover the scratches with a protective layer of primer.
Another disadvantage, which is sometimes overemphasized, is the presence of toxic formaldehydes and phenols, which were widely used in the production of chipboard. However, this problem is not significant, since the production uses the amount of a substance that does not go beyond the limits established by sanitary safety in class E1.
Characteristics of sandwich panels
The thermotechnical calculation of the wall panel showed that with a thickness of the expanded polystyrene layer of 100 mm, the resistance of the plates to heat transfer is 2.8 W / mC, which corresponds to the standards adopted by SNiP. In the same case, if a plate with a thickness of 224 mm is used, the indicator reaches a value of 5.2 W / mC. For example, the indicators of a timber beam with a brick sheathing are 1 W / mos, 400 mm of brick in combination with 80 mm of mineral wool as a heater and a lining layer reach an indicator of 2.02 W / mos.
As you can see, the construction SIP panel with a thickness of 224 mm is noticeably superior to other materials in terms of providing thermal insulation, which in the future will significantly reduce the cost of heating in winter and air conditioning at home in summer.
The calculated performance of SIP panels in terms of providing sound insulation showed that even with a minimum thickness of 120 mm, a mark of 44 dB is reached. With the optimal thickness of wall panels of 224 mm, the sound insulation of the room reaches 75 dB, which is one and a half times higher than that of other building materials.
Types of heaters used
The following types of materials are used as a sealant and thermal insulation:
- mineral wool,
- styrofoam,
- fiberglass,
- polyurethane foam,
Expanded polystyrene has gained the greatest popularity. This material has a cellular structure and demonstrates the following advantages:
Due to the light weight of expanded polystyrene, the installation of panels and the construction of a building from them takes record time, which is why this material is so loved by builders and is used as the main type of insulation.
Mineral wool is good because, like expanded polystyrene, it provides excellent heat and sound insulation properties, and is resistant to external aggressive environments, including high temperatures. Its disadvantages are the impact on human skin when exposed to open areas of the body, which causes discomfort and severe itching. Work on the installation of panels and their cutting must be carried out carefully so that particles of cotton wool do not enter the respiratory tract.
Fiberglass is used extremely rarely, and as a main advantage it offers excellent sound absorption indicators, often reaching 90 dB. However, the poor resistance to heat, when the material begins to deform already at +40°C, did not ensure its popularity.
First of all, it is important to remember, and if necessary, constantly remind yourself: "quality does not come cheap." Most of the problems that arise when buying SIP boards happen precisely because of the wrong choice in the direction of cheapness.
The primary problem that arises when buying plates from an unscrupulous manufacturer is the use of low-quality glue. There were cases when, during production, the adhesive was applied unevenly to the surface of the insulation, moreover, with simple stripes by hand. As a result, the OSB layer is easily separated from the insulation when a certain force is applied.
The second, often common problem, especially inherent in domestic and Chinese manufacturers, is the use of low-quality polystyrene foam, which is easily combustible, while releasing harmful particles. It is important to remember that high-quality material does not spread combustion and is self-extinguishing.
From the foregoing, it makes sense to highlight a few useful tips that will help when choosing and buying:
- before ordering a batch, it is advisable to personally verify its quality,
- there is no need to chase cheapness, because in this case “the miser pays twice”, and not everyone can afford to order a second house,
- plates must be ordered directly from the manufacturer, or from dealers with a good reputation,
- it is advisable to request the option of payment on delivery, in extreme cases, an advance payment. Firms with a low reputation are often characterized by the requirement of 100% prepayment. The factor "money in the morning - chairs in the evening" in this case will play against the buyer.
In general, it should be noted that even high-quality German manufacturers make errors in the size of the plates. Nevertheless, the Egger concern is distinguished by a generally recognized fact of the consistently high quality of its products, followed by Glunz with a small margin. Both manufacturers have a high reputation, confirmed by more than one decade, and thanks to them, SIP panels, which are easy to buy in any building market, will delight you with their quality and reliability.
Panels made of rigid sheathing sheets with insulation enclosed between them - a material that made it possible to speed up and reduce the cost of construction many times over.
American engineer and designer Frank Lloyd Wright, wishing to implement a building project where there would be minimal costs for heating, lighting and air conditioning, in the 30s of the last century invented a composite panel with a honeycomb core. Wright's panels had flaws, but were light, cheap, and safe. American manufacturers of building materials picked up the idea, the technology for their creation was simplified, and panels began to be mass-produced.
Panel materials
SIP (SIP) - a structural insulating panel used in the construction of frame structures. Its middle layer is a heater, the outer ones are. The panels can easily withstand the load and provide reliable thermal insulation. Today, SIP technology is used for the construction of residential and commercial buildings around the world. More than 80% of residential buildings in the US, Canada and Europe are built using SIP panels.
Laminated panels are made from different materials (with steel, aluminum, asbestos-cement sheets), but the term SIP most often means that wood materials are used for the outer layers:
- oriented strand board;
- gypsum fiber sheet;
- drywall sheet;
- Green Board - .
Thermal insulation is provided by foams:
- mineral basalt wool;
- polyurethane foam;
- phenol-formaldehyde foam;
- expanded polystyrene.
The ideal geometry of the panels is fixed by the middle layer, it contributes to the rigid fixation of the facing parts, reinforcing the entire product.

Benefits of using SIP panels in construction
Seismic resistance. Buildings built from SIP panels have been repeatedly tested. Their seismic resistance has been tested using equipment capable of simulating an earthquake of varying intensity.
Material disadvantages
The downside of SIP panels is the combustibility of the materials from which they are made, environmental hazard. Manufacturers that have authority in the market, supplying their products with quality certificates, offer environmentally friendly SIP panels treated with flame retardants. The release of toxic substances by such material does not exceed the sanitary standards accepted throughout the world.
Despite the skepticism of adherents of traditional building materials for Russia, experts predict the widespread use of SIP technology due to the growing consumer confidence.
Watch the Discovery Channel video about SIP panels:
In recent decades, new technologies have been actively penetrating into many spheres of human life. It is impossible not to notice them in construction. New finishing and construction materials tend to unify technological processes, facilitate human labor at all stages of construction and decoration. A striking example of this was the emergence of SIP panels.
What is SIP panels
All about sip panels. The history of the emergence of this building material goes back to the middle of the last century. In Russia, he appeared two or three decades later. The country of origin of SIP panels is considered to be Canada. As a result, houses built using these plates are called Canadian technology buildings.
Structure (SIP) SIP of a panel - multilayered material or a sandwich. An indivisible whole is obtained thanks to special adhesives and resins. Density is achieved due to powerful pressing. At the same time, the material remains relatively elastic, capable of small deformations, and at the same time it has a fairly low specific gravity.
Let's name the composition of these panels:
- insulation;
- OSB sheets (oriented strand board).
As a heater, the manufacturer reserves the right to use a variety of materials:
- Foamed plastic (aka expanded polystyrene);
- Mineral wool;
- Fiberglass;
- Polyurethane foam.
Such a wide choice of fillers can be explained by the desire:
- Give the consumer the right to choose;
- Reduce cost;
- Increase versatility;
- Reduce dependence on temperature and humidity.
In turn, the OSB consists of 4-6 layers of wood chips impregnated with resins and a solution of boric acid. To minimize the combustibility of this material, treatment with fire retardants is called upon - substances that prevent ignition and direct combustion.
Table 1. Standard sizes of SIP panels
The composition of the SIP panel:
Non-round thickness values are explained by the standards used for OSB sheets - 9 and 12 mm. Thus, standard insulation thicknesses are also visible: 100, 150, 190 and 200 mm.

Advantages over competitors
The composition of SIP panels and the proportions of their filler made it possible to identify the main advantages of avant-garde panels in the laboratory. So 174 mm sandwiches are equally capable of retaining heat equivalent to walls made of:
- Timber 520 mm thick;
- Foam concrete 600 mm thick;
- Brick thickness 2300 mm;
- Concrete 4500 mm thick.
These results may seem fantastic, but the facts remain the facts. At the same time, we will name a few more remarkable properties of SIP panels:
- Good sound insulation;
- Quick installation on site;
- Assembly of buildings can be carried out at any time of the year;
- Standard sizes make it easy to transport; warehousing and storage;
- Relatively low cost (from 25 US dollars per square meter).

SIP panels in action
Such a long list of advantages of sip panels can be continued, but let's dwell on how they behave directly in work.
Experience shows that installation does not require high qualifications. In this case, a minimum of tools is used. The dynamic loads of this building material can be called quite impressive. So sip panels to build easily cope with a load of 2000 kg in the transverse direction and 1000 kg in the longitudinal direction.
At the same time, the reliability of internal fastenings, hooks and holes for furniture is comparable to fastening to concrete.
Low specific gravity of the panels (the weight of one square meter of a 174 mm thick sip panel is 19 kg). For comparison, we can say that the wall is of the same size, but from will weigh about twenty times as much. Thus, houses made of sandwich panels do not require strong foundations even when building a building with several floors.
Perhaps what can spoil the mood here is the desire to save money and the associated purchase of sip panels from an unverified seller. When it comes to building a house and for yourself, saving on reliability and quality is absolutely inappropriate.
Houses from sip panels are built in the shortest possible time
What's stopping you from being perfect?
It would be naive to say that sip panels are solid advantages. There are still “points” in them, to which creative and scientific thought will have to be applied.
So the construction of NIB panels provides for:
- The presence of a metal frame;
- These designs do not tolerate backlash;
- Poor-quality filling of insulation is a prerequisite for freezing walls.
Hidden defects in panels can provoke the accumulation of condensate, which sooner or later will lead to a defect in walls or partitions.
One of the main arguments of skeptics is the combustibility of the material. Meanwhile, thanks to a special treatment, sip panels are seven times less prone to burning than ordinary wood. In continuation of this topic, the consumer is afraid of toxic emissions from a fire. Alas, even here one can upset those who doubt. The special treatment of smallpox and the chemical composition of the fillers prevent not only the ignition of the structure, but also the process of its combustion as a whole.
By the way, we note that there are still several types of Sib panels, the use of which is recommended only for utility buildings.
It has always been like this - the new and advanced had not only its supporters, but also opponents. For every human step towards progress, there have been and will be opponents and skeptics. At the same time, logic and experience have always been assistants in the search for truth. We hope this will be the case with SIP panels. Their advantages will be allies of those who advocate moving forward, which means that the day is not far off when houses built using this innovative building material will be taken for granted, and their owners will be considered far-sighted and practical people.
Sip panels are a convenient material with excellent characteristics and a long service life, allowing you to build buildings in the shortest possible time. Sip panel houses have their strengths and weaknesses, which will need to be studied in detail. This material gained its popularity in Canada, but after it began to be actively used around the world. Sip technology for building houses is not particularly difficult, so this material has recently been used more and more often.

Panel composition
The advantages of sip houses are provided due to the composition of this material. It consists of the following elements:
- The basis of such a product is OSB-plate. These slabs are made on the basis of long and narrow chips, stacked in layers and compacted so that they lie perpendicular to each other on all sides of the sheet. Such a production technology increases the flexibility of the product under loads in different planes, such properties are not available in ordinary wood. Often, chips based on pine or aspen are used for sip panels. These boards are 97% wood, the rest is binder components. The structures are treated with a special water-repellent solution, which provides protection against moisture, decay and mechanical stress.
- Expanded polystyrene is also used, which is characterized by low thermal conductivity with light weight. Gas is added to the polystyrene mass during manufacture. Depending on the properties of the product, the substance can vary greatly, for example, carbon dioxide is used for fire-resistant structures. A sheet of such a product with a thickness of only 11 cm is able to provide a level of thermal insulation comparable to a wall consisting of silicate brick 2 m thick.

Panel characteristics
To evaluate the quality of a house made of sip panels, the pros and cons of using such material, you need to carefully study its characteristics. According to European standards, the material has the following dimensions:
- The width can be 1.25 or 1.2 m.
- The length can be 2.5 or 2.8 m, in some cases 3 and 6 m.

Product thickness can vary greatly. Basically it depends on the layer of thermal insulation. The insulation can be 100, 150 or 200 mm thick.
On our website you can find contacts of construction companies that offer the service of building houses from SIP panels. You can directly communicate with representatives by visiting the exhibition of houses "Low-Rise Country".
Advantages of using sip panels
For the construction of any building, you first need to make a foundation. When using brick or monolithic structures, it is necessary to create a basis with a large laying depth. Sip technology will help to significantly reduce the size of the foundation. This is because the walls after construction will not exert much pressure on the base. The average weight of one panel will be no more than 60 kg.

The main advantages of such panels include:
- High rates of fire resistance. During the experiments, experts found that the material is able to hold fire for a whole hour. The product also has the ability to self-extinguish. This is due to the presence of an antiperine in the composition. Stories of well-burning sip panels are a myth that usually refers to craft products from unverified manufacturers.
- The material is environmentally friendly and does not emit any harmful substances during combustion. All components are completely safe for humans.
- High levels of strength. This is one of the key advantages of the panels, which is very important in the construction of buildings. Walls made of such material are able to withstand heavy loads.
- stability. This characteristic can be improved by adding a stiffening frame using bars inside the structure.
- The rigidity of the material. It is achieved thanks to a special production technology.
- High service life. On average, sip panels can last more than 50 years.
- Small material thickness. This property is very useful when building a building.
- Various materials can be used for interior and exterior wall cladding. Ideally smooth surfaces of the panels do not require any preliminary preparations.
- There is no need for additional insulation of the structure, sip materials are already equipped with foam insulation.
Cons of sip panels
They have sip panels and disadvantages, which will also need to be taken into account when choosing such a material. Knowing the weaknesses of such structures, you can try to fix them, this will help extend the life of buildings. The main disadvantages of sip panels include:
- Flammability is one of the main disadvantages of sip panels. Although compared to wood, panels have a high resistance to fire, they still burn easily. When building a house, it is extremely important to do the wiring correctly, choose the best places for placing sockets and switches, in order to avoid a possible fire in the house. For additional protection, you can use a substance - antiperen. Also, to increase the fire resistance, you can sheathe the walls with non-combustible material.
- In rare cases, panels can be damaged by rodents. During construction, it is important to take into account all the joints so that there are no gaps through which rodents can penetrate.
- A structure made of such material can be destroyed by intruders, which will allow them to get inside the house.
- Building tightness. If ventilation is not taken care of in a timely manner, the humidity in the room will increase significantly, which will lead to the formation of fungus and mold.
- During operation, the plates gradually dry out, which leads to a decrease in their size. Because of this, gaps can form between the plates.
- Finishing the house will need to be carried out in any case. The fact is that the plates are subject to mechanical stress, and if they are scratched, they will quickly lose their attractive appearance. So it is better not to put off facing procedures indefinitely.

Features of construction using Canadian technology
In order for the building to turn out to be reliable and durable, you will need to take into account the features of using sip panel technology. These include:
- It is necessary to try to choose the highest quality materials. Only high quality panels will be able to withstand all the pressure exerted on them. Some manufacturers may use a poor quality adhesive that will cause the designs to come loose quickly. Also, poor-quality materials can lead to easy ignition of the structure and the release of harmful substances during a fire. The choice of the manufacturer must be approached with all responsibility.
- When choosing a foundation, it is better to give preference to screw piles or tape monolith. This will reduce construction costs.
- The special manufacturing technology of the panels provides them with high rigidity. Thanks to this, the construction of the building can be carried out at any time of the year, even at low temperatures. The building after construction does not shrink and is protected from seasonal soil movements.
- Particular attention must be paid to the frame that will hold the walls. For exterior decoration, it is better to use thicker varieties of sip structures; ordinary panels are suitable for interior partitions.

Knowing the characteristics of sip panels, the disadvantages of their use, it is possible to erect a building without any special complications. The main thing is to carry out all the work in stages and in compliance with the technology.
Assembly of sip panels
The assembly of such material should be carried out with careful control of the reliability of the connection of each section of the structure. The main fastening points for sip panels are:
- Areas of docking of the floor structure with the main part.
- Elements for fastening the corners of the walls.
- Joints connecting walls, ceilings and roofs.
- Elements fastening the roof with panels.

All installation procedures for joining structures must be additionally reinforced using self-tapping screws and fixed with special foam for installation. Although the material has good thermal insulation performance, poor assembly may cause a problem of drafts. Cold air can enter the space where the panels are poorly connected to each other. If such complications arise, you can get rid of them with the help of construction mounting tape.

In this issue, we will analyze in detail the common mistakes in building a house from sip panels. A sip house is the same frame house, but inside with a wooden skeleton, inside of which panels are laid. What should the frame of the house be made of? How to know the moisture content of a material? About all this: in the next video?
The choice of foundation for sip houses
The construction of any house begins with the choice of foundation. For panel buildings using Canadian technology, the following types of base can be used:
- A screw foundation is the most optimal solution, as it will allow you to build a plinth with ventilation, which is extremely important for sip panel buildings with contraindications to high humidity. This basis has a long service life and allows you to expand the house at any time by adding an extension.
- A shallow foundation is also an excellent solution. It is durable and low cost.
- For unstable ground, an excellent solution would be to use a base based on reinforced concrete slabs.

Conclusion
Like any other construction technology, a sip panel house has its pros and cons. But it is important to remember that a house built according to the technology of sip panels can serve as a full-fledged year-round dwelling. Subject to all norms, he will delight his owners for many years.
SIP panels are a modern building material that is successfully used for the construction of private houses.
SIP-structural thermal insulation panel consists of three layers, the inner (No. 1), as a rule, polystyrene, extruded polystyrene foam or polyurethane foam and lining, the outer layers (No. 2,3) are OSB boards. The boards are bonded to the insulation with a strong polyurethane adhesive.
Due to their layered construction, the panels perfectly withstand temperature changes and excessive moisture.
The outer side, OSB board, consists of wood chips, paraffin emulsion and synthetic resins. All binders are thoroughly tested and are environmentally friendly materials.
Thanks to this design, when building houses from SIP panels, the maximum level of thermal protection is achieved.
According to external similarities, this material is often called sandwich panels. The outer layers are mostly designed to provide resistance to mechanical stress, and the inner one is a heater.
The connection of SIP panels occurs by the method of grooves. A beam is attached to one end of the panel, and a groove is made for it from the opposite end. Thus, the panels seem to be inserted into each other.
Such a connection has certain advantages. The first of them is the actual absence of cracks, and the second - a wooden beam gives additional strength to the structure, creating a kind of frame.
Advantages of houses from SIP panels
- The materials from which SIP panels are made are absolutely safe for the environment and humans.
- The final cost of a house built from sandwich panels is often significantly lower than that of a similar one made of brick or wood.
- During the construction of this material, the geometry of the house is very clearly observed. The SIP panels themselves are perfectly flat and require only the correct leveling, while brickwork, for example, is much more difficult to lay strictly vertically and horizontally.
- Durability is another distinguishing feature of sandwich panels. A load of 15 tons vertically and 2.5 tons horizontally makes it possible to build even load-bearing walls from SIP panels.
- The light weight of the material allows you to do without expensive types of reinforced concrete foundations. It also greatly simplifies the installation process and does not require the use of large construction equipment.
- SIP panels are a powerful insulation, as they have low thermal conductivity. This allows you to save on heating and not reduce the useful area of \u200b\u200bthe house due to additional interior cladding.
- Among other things, sandwich panels are non-combustible material. During the production process, all its layers are treated with fire-resistant impregnations.
- The outer layers of SIP panels made of OSB are treated with a special moisture-proof compound that prevents the material from getting wet. Expanded polystyrene is not subject to rotting in principle. Thus, the walls of your house will be protected from the harmful effects of moisture, fungus and moss.
It should also be mentioned that the simplicity and convenience of sandwich panels allows the construction of houses with various architectural forms and frills. The layout and area of \u200b\u200bthe building can be absolutely any, its choice will depend only on your desires and preferences, and not on what the material will allow.
Construction of houses using SIP panels
The construction of prefabricated houses from SIP panels originates from the countries of North America and Europe. The frame structure of such panels is energy efficient and heat resistant. Due to the high rates of environmental friendliness and durability of the construction of frame-panel houses, this method has become an excellent alternative to building houses from brick or log beams.
Construction of frame houses from panels
The main advantage of building from SIP panels is the speed of building construction. It takes from one to two weeks to assemble one medium-sized house, and the whole process takes place right in front of the customer. Installation of a building from SIP panels is notable for its simplicity, so the customer can start building a house on his own, following the assembly instructions.
The panels are equipped with ready-made window and door openings and do not require additional processing. Thanks to the place allotted for each panel, the assembly of the house resembles a designer.
The construction of a house structure from SIP panels begins with a foundation made in a columnar or pile-screw method, which prevents excessive shrinkage of the house. After that, the material is laid on the structure, the foundation of the first floor, consisting of a waterproofing material.
After preparing the first floor, the first corner post is mounted, to which the outer walls and partitions are subsequently attached using the “groove-thorn” system. Upon completion of the installation of the first floor, the subsequent floors and roofs are made using identical technology.
All ceilings and OSB panels are covered with a special non-combustible and environmentally friendly insulation. Thanks to this technology, the entire structure of the house does not require additional insulation.
After the complete installation of the walls, all surfaces are primed, and the joints and seams are glued with a reinforcing mesh. The facade of such a building after priming can be covered with vinyl siding or textured paint to choose from. 
Upon completion of the main facing work, it is necessary to install double-glazed windows and their lining. In most cases, polymer-sand tiles are used as a roof for pre-fabricated houses made of SIP panels.
Houses made of SIP panels are highly durable, environmentally friendly and have a long service life.
