Penoplex insulation. Penoplex review. The cost of material and installation work

Among the extensive line of heat-insulating materials, foam plastic occupies one of the first places. Most fans of doing something with their own hands are attracted by the low price of the plates of this insulation and the ability to mount them on their own without resorting to the help of workers.

This allows you to significantly save on the insulation of private and country houses. Due to the low thermal conductivity of the foam, the finished structures are quite warm.

What is extruded polystyrene foam

The complex technical name of the insulation alarms many who prefer to use only environmentally friendly, low-combustible materials in the insulation of their homes. Modern technologies make it possible not to use freons as a blowing agent. Therefore, only CO2 or freons are currently used for polystyrene foam granules. So we can quite call it environmentally friendly.

The material has a number of characteristics that make it very attractive for private and low-rise construction, as well as for industrial use.

• The insulation does not have a biological component, therefore it does not rot and does not decompose. Such properties make it durable (service life ≥ 50 years).
• Eco-friendly heater. And we can even talk about the environmental friendliness of its production.
• Perfectly proved itself in the "warm floor" systems. On top of the foam 35, the entire structure of the "warm floor" is mounted. A low coefficient of thermal conductivity will effectively save heat, so that the cost of heating a house or apartment is significantly reduced.
• Wide range of applications. Insulation can be used both in a country house and at an airfield.

Technical characteristics of penoplex are presented in the table below.

Where can you use penoplex

Extruded polystyrene foam has found its application in various fields, both in residential construction and repair, and in industry.

Its technical characteristics have a wide variation in such indicators as plate thickness, combustibility, strength, which allows them to insulate both runways at airfields (100 mm thick plates), and house walls, foundations, etc.

Penoplex markings

Penoplex marking

There are several markings for penoplex, such as M35, M45 and others. It is worth noting that this is an old marking. They are currently out of production.

• Modern markings - 31C, 35, 45. Penoplex 31C has poor compression specifications, so it is used mainly for insulating pipes or containers.
• Penoplex 35 is universal, quite durable, so it can be used to insulate both pipes and walls of buildings, foundations, and use it in a screed on the floor. The characteristics of this brand have excellent thermal insulation qualities.
• Penoplex 45 can be successfully used for warming runways at airfields, for insulating deep foundations, floors in industrial premises. It is also indispensable in the arrangement of the road surface. Its density, which is higher than that of 35, perfectly withstands loads, and the almost complete absence of water absorption does not allow the canvas to swell after heavy rains and subsequent frosts. For 45 there are no prohibitions for use on an industrial scale.

What is good penoplex

The properties of penoplex are diverse, which is very convenient for do-it-yourself work, in the country or in a private house.

1. Ease of installation and low weight make it easy to mount this heater without resorting to the help of specialists.
2. Such characteristics of penoplex as low thermal conductivity, density and others allow it to be used not only for external insulation, but also for thermal insulation of floors at the construction stage. Slabs with a density of 45, with a thickness of 50 mm or more, can easily withstand a concrete screed, serving as an excellent service in the future. You will always have a relatively warm floor.
3. Foam boards 20 mm, 30 mm, 50 mm thick and above will make the walls, floor and roof warmer. Now you don't have to worry about buying warm slippers or a sweater. Penoplex will reliably protect you from bad weather.
4. Such a quality of penoplex as vapor tightness baffles many. After all, we are used to counting and hearing from sellers in hardware stores that the walls (floor, roof) must breathe. But think about it. Through these micropores, our house (wooden or brick) not only breathes, but also loses heat. Using penoplex insulation, simply organize high-quality ventilation in your room by equipping, for example, a micro-ventilation system and installing an exhaust hood. Thus, you will create a healthy microclimate in your home.

A little about the flammability of foam

Most homegrown builders believe that foam plastic is no different from polystyrene, except perhaps in its structure. Its properties such as combustibility and water absorption are equated to the properties of foam. This is not true.
Now both non-combustible foam and completely combustible foam are produced. Therefore, trusting the rumors that the penoplex burns strongly or not is your decision. However, we note that penoplex is deprived of the possibility of spontaneous combustion. In the presence of a source of constant fire, it only melts, with the release of carbon monoxide (CO) and carbon dioxide (CO2) gases. If the fire is immediately extinguished, even smoldering will not be observed. Therefore, choosing between modern foam plastic and foam plastic, give preference to the second material.

Important. Ordinary foam plastic burns perfectly, which you can easily find in a box with some household appliances. But it is foolish to assume that there is no difference between him and the construction foam. None of the varieties of penoplex does not burn, but only melts in the presence of an open flame source.

Russian brands of foam

Russian craftsmen did not bypass the production of such a sought-after insulation as penoplex. In our market there are such brands as "Technoplex" from the corporation "TechnoNIKOL" and "Polyspen". Let's consider each of them in detail.

Technoplex is designed specifically for private construction, as well as for arranging the underfloor heating system. Nanotechnology is used in production - graphite particles, which enhance the effect of low thermal conductivity and further increase the strength of the material plates. The plates of this insulation are light silver and meet all standards for the production of foam.

Technoplex insulation is produced by plates with different parameters. Even custom sizes are possible if requested by the customer. The thickness of the plates is different - 20, 30, 40, 50 and 100 mm. All plates, except for the 20s, have a special edge, which during installation eliminates the appearance of cold bridges. Technoplex boards can be stored both indoors and outdoors, provided that the original packaging is intact.
After installation, the surface of the Technoplex insulation must be isolated from atmospheric influences.

Polyspen LLC successfully produces extruded polystyrene foam under the same brand. There are three types of foam boards in production, which differ from each other in characteristics - compression density, thermal conductivity coefficient and combustibility. These are the brands:

• Polispen Standard

The numbers 35 and 45 mean the density of the material, respectively 35 kg/m3 and 45 kg/m3. In the production, special substances are used that reduce flammability - fire retardants.

Plates "Polyspen Standard" are used where their combustible component is least important - for internal floor insulation, in foundations. Plates with a density of 35 are used for insulation of fences and load-bearing structures of buildings. Plates "Polispen" with a density of 45 are used in the arrangement of road surfaces, as well as structures that carry excessive loads.

So, we have an excellent thermal insulation material, made in the form of plates of various thicknesses - 20, 30, 40, 50, 60, 80 and 100 mm (depending on the manufacturer, the thickness range may vary, the standard range is 20/30/40/50 / 100), impregnated to varying degrees with flame retardants (the price of non-combustible material is more expensive), of various density and compressive strength, used both in private housing construction and in industry. Russian brands of penoplex, such as Tenoplex and Polispen, have proven themselves well in the Russian market.

To make it comfortable to live in the house in any weather, so that even in winter you could go out on the loggia without warm clothes, you need high-quality insulation of walls, floors, ceilings. Today, many new heaters have appeared that protect house structures from heat loss. And among them stands out penoplex. Why has it become so popular in industrial and domestic use, what are its advantages and where is it used?

Reasons for popularity

Penoplex insulation has now become very popular in the insulation of buildings. They protect everything - from foundations to ceilings on balconies.

This is due to the fact that the material attracts with its most important properties:

• Working with it does not require special skills and knowledge,
• It is inexpensive, and insulation is economical in price.

What is penoplex

Penoplex insulation is an extruded polystyrene foam. In its structure, foam plastic - be it 31, 45. 31 - resembles the well-known foam plastic, but it has slightly different characteristics due to the peculiarities of production.

During production, polystyrene foam granules are foamed with freon or carbon dioxide. This allows you to get a material that is absolutely harmless to health, hypoallergenic and has a number of advantages over polystyrene foam and other heaters.

Penoplex is produced in the form of plates. Technical characteristics of foam insulation are considered one of the most optimal for building protection. The dimensions of the plates are standard, but they can be cut.

Material properties

Penoplex does not contain any biological substances. Therefore, it never decomposes or rots. At least in the foreseeable future, the material cannot decompose under the influence of the environment and microorganisms - manufacturers claim that its service life reaches 50 years or more.

The material has a very low thermal conductivity of 0.03 W / m ºK, so it is a universal insulation.

Penoplex is currently used for:

• building insulation,
• road insulation,
• runway insulation.

Specifications

• Significant flexural and compressive strength,
• Its water absorption is 0.2-0.3%,
• The vapor permeability of the material is 0.007-0.008 mg / m h Pa,
• Temperature resistance - the insulation retains its characteristics and properties at temperatures from -50 to + 75 degrees.

Pros of penoplex

Thanks to these technical characteristics, the insulation has the following advantages:

• The material is resistant to burning and is considered fireproof,
• Serves without loss of its qualities for a long time - from 50 years,
• Does not emit toxic substances into the air during operation,
• Does not absorb moisture
• Simple and easy to use.

Types of foam

At the moment, several types of penoplex are produced, each of which has its own areas of application. Although this is a fairly versatile material, it is still better to follow the recommendations of the manufacturers and use different types of foam for certain types of work.

Penoplex is of the following types:

• Penoplex Wall has a density of 25-32 kg / cu. m. and serves to insulate walls and partitions of buildings, basement floors.
• Penoplex Foundation has a density of 29-32 kg / cu. m. and serves to protect foundations from freezing, basements, basement floors. The water absorption of this type of material is almost 0.
• Penoplex roof has a density of 28-33 kg/cu.m. It is characterized by exceptional lightness, moisture resistance and rigid construction. Therefore, it is more convenient for them to insulate roofs of any kind.
• Penoplex insulation 31 perfect for insulating walls, ceilings, floors. It is widely used for warming loggias and balconies, as well as for protecting a number of roofs that are not in use - that is, they are not loaded with anything other than snow during precipitation.
• Insulation 35 designed for floor insulation and is especially often used to create underfloor heating.
• Insulation foam 45 has a density of 35-47 kg / cu. m. and has a number of special characteristics that allow it to be a universal material. Its compressive strength reaches 10% and is equal to 0.5 MPa. Its water absorption is such that even when completely immersed in water, the insulation 45 is practically not impregnated with water.

Due to its qualities, it is used for the insulation of industrial facilities. Penoplex 45 is widely used for warming runways, any roads - railway tracks and asphalt road surfaces, especially if they are laid on heaving soil and permafrost; insulation of floors, foundations, roofs.

Penoplex 45 allows you to insulate precisely operated roofs, which can be driven by vehicles, as well as floors that have a heavy load. Therefore, 45 is used for the insulation of industrial facilities.

If we are talking about the construction of residential buildings, then in the field of insulation of foundations and walls, especially in harsh climates, foam 45 is practically unrivaled.

Important: All types of penoplex are not afraid if they freeze, thaw and freeze again. At the same time, this does not affect their properties in any way. They are resistant to acids, salts, alkalis, lime, alcohols, water-based paints, ammonia, cement, animal and vegetable oils.

Application features

Penoplex plates are easy to cut - they can be given the desired dimensions with conventional cutting tools. After cutting, the slabs are stacked and fixed. It is necessary to choose glue for penoplex based on the manufacturer's recommendations. Keep in mind that some adhesives can damage it. The material is resistant to gasoline, kerosene, benzene, polyester resins, acetone, oil paints.

Plates can be stored outdoors. But we must protect them from lying under the sun for a long time, since in the light the upper layers of the material begin to collapse.

The technical characteristics of the material make it an almost ideal insulation. Therefore, it can be used in almost any conditions and on any objects. And the ease of installation and work with it make it available for independent work.

When it comes to home, the first associations, in addition to cosiness, are also comfort and warmth. Therefore, heaters of various types and made from various raw materials will not cease to arouse increased interest among consumers. The use of this material is becoming a steady trend, so it is worth familiarizing yourself with the characteristics of foam plastic and the methods of its installation in more detail.

Plates penoplex

Penoplex is a foamed polystyrene obtained by extrusion.

• The process itself was invented more than half a century ago in American laboratories. The result was the emergence of a new material with a structure of many small and completely "sealed" cells, not exceeding 0.2 mm in size and forming a uniform surface.
• A foaming additive is introduced into the polymer granules, which combines with them under pressure and when heated to a certain temperature. The resulting mass is forced through the extruder. Foaming agents (and mainly carbon dioxide and a mixture of light freons) are non-toxic materials, they are non-flammable and do not emit harmful substances. In addition, as soon as the manufacturing process is completed, all these auxiliary additives are replaced by air from the environment.

Penoplex photo

As a result, a heat-insulating product is obtained with good performance for materials of this group, designed to save heat. These include:

• low thermal conductivity;
• strength;
• minimal moisture absorption.

Such characteristics provide penoplex with a constant presence at private construction sites and large-scale industrial buildings.

The slabs of material are packed in a film that protects from the penetration of sunlight. The original packaging allows you to store expanded polystyrene outdoors. But, despite the plastic film, it is worth providing them with additional protection from UF rays, which can damage the top layer of insulation. Other special storage conditions are not required, because expanded polystyrene is not afraid of humidity and temperature changes, the main thing is to control the safety of the package.

Types of penoplex and applications

Five existing brands of this insulation have a fairly wide range of uses.

• Penoplex 31 C has density indicators from 28 to 30 kg/m³. Refers to the flammability group G4. Applicable in the following areas:
• insulation of foundations in the horizontal and vertical direction, as well as roofing on a reinforced concrete base;

• when laying pool bowls, engineering networks, when isolating thermal bridges;
• insulation of various underground structures - fire wells, storage tanks;
• during the construction of local water supply and sewerage systems in private homes, provided that communications are laid in the freezing zone;
• class 31 C foam slabs are also used for the installation of shallowly buried foundations.
• Penoplex 35 produced with a density of 28 to 37 kg/m³. Flammability group G1. It is used, like the above-mentioned variety, in the insulation of foundations in two directions, roofs (including corrugated board, and pitched), cold bridges and engineering networks. In addition, penoplex 35 is advisable to use:
  • when insulating walls;
  • when laying foundations as insulation under the sole;
  • in the floors of residential buildings, warehouses, freezers and ice arenas.

Separately, it should be said that at the time of production of this brand of expanded polystyrene, special additives are added to the feedstock at the mixing stage, which increase the resistance of the insulation to combustion. Such plates do not burn well and prevent the spread of fire further, and when smoldering, they emit only two types of gases (carbon dioxide and carbon monoxide), unlike a number of other insulating materials that “release” a whole range of harmful substances and compounds.

• Penoplex 45 C has a density of 35 to 40 kg / m³. Flammability class - G4. It is applied to warming of the bases operated under loading of roofs and floors.

• Penoplex 45. Density index from 38 to 45 kg/m³, flammability group G4. The scope coincides with the above types of material. And besides this, it is used for warming floors, foundations and roofs that can withstand heavy loads. That is, the material will not collapse when exposed to a load of up to 50 tons per 1 square meter.
• Penoplex 75 not used in building construction. Its density of 40 to 53 kg/m³ makes it possible to use it in the construction of runways for airfields and aircraft hangars.

Penoplex characteristics

• The density of the insulation, depending on the brand, can be from 28 to 53 kg / m³.
• Penoplex is recommended to be used only in the temperature range from -50°C to +75°C. Compliance with operating temperatures is a guarantee that the material will retain its technical characteristics. If this condition is violated, the foam boards can be deformed and lose part of their thermal insulation and mechanical characteristics.
• When choosing an adhesive composition, you should carefully read its instructions and read the manufacturer's recommendations regarding the use of the product for gluing polystyrenes.

• Plates of extruded polystyrene foam foam have good chemical resistance to most substances and materials used in construction. These include:
  • wood preservatives (only water-based, solvent-free);
  • bituminous mixtures;
  • cement;
  • lime.
• Substances containing a solvent can have a destructive effect on the foam, lead to its softening and, as a result, shrinkage of the material plates. The group of substances with which contact should be avoided when working with expanded polystyrene foam include:
  • paint thinners;
  • coal tar and its derivatives;
  • solvents (acetone, petroleum toluene, ethyl acetate).

• Penoplex plates do not pose a threat to human health and are not dangerous to the environment, which is confirmed by research and certificates for these products.
• Penoplex material can be characterized by several more indicators.
• Low thermal conductivity (thermal conductivity at 20-30°C - 0.030 W/(m×°C)). The score for this evaluation criterion is significantly lower than the average values ​​for most other insulation materials.
• Tests of plates for water absorption showed that the sample immersed in water collected moisture for the first 10 days. And for a month he absorbed no more than 0.6% of the volume. That is, at first, the cells located closer to the surface slowly took in water, and after they were filled, the liquid no longer penetrated. The low water absorption of foam plastic makes it possible to use it in conditions of high humidity without changing the thermal conductivity. That is, expanded polystyrene can be used without additional waterproofing, if certain environmental conditions do not require it.
• In terms of vapor permeability, a foam slab 2 cm thick is equivalent to a layer of roofing material.
• It is able to maintain its properties even with numerous frosts and subsequent thawing. Their service life is at least 50 years.
• The extrusion method used in the production of boards results in a uniform and dense structure of the finished product. This gives the foam a consistently high compressive strength.
• Many have already appreciated the simplicity, ease of operation and installation of extruded polystyrene foam. The material has no restrictions on use in any weather conditions, nor does it require protection from precipitation. Easy processing and simple cutting with a regular knife is extremely appreciated by builders.

Do-it-yourself foam insulation

Extruded polystyrene foam, for all its versatility and remarkable characteristics, will become useless if the technology is violated during the installation process. Therefore, consider the stages of foam insulation.

Installation of penoplex from the inside of the building

• Preparatory work. The standard procedure for all types of construction and finishing works is followed in this case as well. Be sure to completely remove all traces of previous surface finishes and paintwork materials. You will have to get rid of the fungus and mold with a special composition, and after that it is recommended to carry out a “sanitary treatment” with any purchased means that have a bactericidal property. The surface should be as smooth and primed as possible.
• Base profile assembly. The installation of this special design is necessary for a more even and tight fit of the expanded polystyrene plates. The profile will also protect the insulation from external influences. Its fastening is carried out on dowel-nails, and lining washers will help to ensure a snug fit of the canvas to the surface being trimmed. An important requirement is the correspondence of the width of the basement profile to the thickness of the foam board. With the help of docking plates, adjacent structural elements are joined together. Be sure to leave a distance of about 2 mm between them.

• Installation of insulation boards. A layer of glue is applied to the foam plastic around the entire perimeter of the material and in the center. Many professional builders advise not to save money, it is good to coat the entire slab with adhesive. After that, the foamed polystyrene is pressed against the profile. Protruding excess glue is removed, and it is better to fill small gaps with inserts from pieces of polystyrene foam that remained during trimming. The issue of using mounting foam for these purposes is controversial. Some craftsmen do not see anything wrong with its use, but there are opinions that such sealing can lead to cracking.
• Final fastening. After the glue has dried (about 3 days), work continues. With the help of fungal dowels, the final fastening of the material takes place. The hardware is located in the middle of the plate and along its perimeter, but in such a way as to connect adjacent sheets.

• Wall insulation from the side of the living space is not always appropriate. The main disadvantage is the reduction in space due to the thickness of the material. Therefore, the most common type of sheathing is outside.

How to insulate with foam plastic outside the building

• In this method of insulation, you will need a material with a thickness of 80 to 100 mm. The stages are similar, but there are some nuances.
• The facade is leveled, cracks are repaired and the wall is primed as a “final” treatment.
• Penoplex is glued as described above and, according to the same principle, is attached to the dowels.
• If plastering is planned, then as a preparatory stage, it is only necessary to stick a reinforced mesh.
• If the final finish is presented using PVC panels or siding, then, accordingly, you will have to take care of the vertical guides for their fastening. An additional layer of vapor barrier is not needed, and insects and rodents do not threaten expanded polystyrene.

As you can easily see, all the work is quite simple to do on your own. The situation is more complicated with the insulation of the outside of apartments in a multi-storey building. In this case, the services of industrial climbers cannot be dispensed with.

Thermal insulation of the floor with foam

• One of the ways is insulation on the logs. This option is suitable for wooden houses installed on a columnar foundation. In this case, slabs of extruded polystyrene foam are in between the joists.
• First, the old floorboards are dismantled if the insulation process is already in the living room, and not at the construction stage. If they are planned to be returned to their place, then this is a good reason to consider each for integrity and treat it with impregnation with protection against decay.
• The installation of new logs begins from the outermost beam, leveling it, and then the beam is attached from the opposite end. Now, having stretched a fishing line between them, you can install the rest of the logs based on it, not forgetting to check that they are located strictly in a horizontal plane.
• A layer of waterproofing is attached to the assembled beams using a construction stapler. The edges of the film should reach the middle of each guide.
• Foam boards are laid on top. It is recommended to place it in a checkerboard pattern. It is necessary to make sure that the composition of the mounting foam, which will process the seams, does not include toluene, which can have a destructive effect on the material.
• The final fixing of the penoplex occurs with the help of dowels, and the boards are again mounted on top.

Another laying technology involves insulation followed by a cement screed. It is available for execution both during repair work and during the construction of a building.

• First, an even layer of gravel 30-40 cm high is poured onto the soil. It is carefully compacted, and sand (about 10 cm) is laid in the second layer. The pressing procedure is repeated with him too. A reinforcing cage is assembled, which is poured with concrete. After the screed dries, the actual warming of the surface begins.
• Waterproofing is easiest to do from dense polyethylene.

• Penoplex plates, as in the previous version, are staggered. A reinforcing mesh is stretched from above.
• After fixing the polystyrene foam, the screed is refilled. She is allowed to dry and the flooring is laid.

The use of extruded polystyrene foam as a heater is a worthy alternative to any other way to protect your home from heat loss and create additional sound insulation. And although it has a lot of advantages, the main pleasant moment in using penoplex for many is still its availability and ease of installation.
