Penoplex sizes. Density of penoplex and its technical characteristics

Thermal insulation materials are building products designed to protect the enclosing structures (walls, floors, roofs, foundations) of buildings and structures from heat loss, in other words, to reduce the thermal conductivity coefficient.

Today we will talk about penoplex (penoplex) - one of the types of thermal insulation in modern construction.

What is penoplex insulation?

Penoplex slabs are extruded polystyrene foam, produced in the form of slabs. The structure of penoplex is similar to the structure regular polystyrene foam, however, penoplex has a number of advantages - primarily higher density and strength.

Technical characteristics of penoplex:

• low thermal conductivity (thermal conductivity coefficient 0.03 W/m·ºK);
• high strength (both compressive and bending);
• low water absorption (no more than 0.2 - 0.4% by volume in 24 hours);
• low vapor permeability (vapor permeability coefficient 0.007-0.008 mg/m h Pa);
• durability over 50 years;
• combustion resistance;
• environmentally friendly (non-toxic, non-rotting);
• wide operating temperature range (-50…+75ºС).

Extruded polystyrene foam is available in several types (depending on density and area of ​​application) in the form of slabs of standard sizes, which are not difficult to install and can be easily cut to the desired size.

The table shows the estimated cost PENOPLEX COMFORT, suitable for insulating foundations, walls, floors in cottages and apartments. The price depends on the quantity of material purchased - the larger the volume, the lower the price, and of course on the region of residence.

"Penoplex WALL"(density 25-32 kg/m3) – intended for insulation of external and interior walls, partitions, plinths for effective heat conservation and savings on heating costs for building premises. These slabs are also used in the construction of buildings when constructing walls using “well masonry”.

In case of insulation of external walls with penoplex, a plaster system can be made on top of the insulation using a mesh, or it can be lined with any façade cladding material (siding, tiles, lining).

"Penoplex FOUNDATION"(density 29-33 kg/m 3) – used in construction basements, construction of foundations, insulation of septic tanks. Penoplex FOUNDATION slabs have increased strength and a practically zero water absorption coefficient.

"Penoplex ROOFING"(density 28-33 kg/m 3) — specially produced slabs for insulation of flat and pitched roofs. Lightweight, rigid, moisture-resistant material with excellent thermal insulation properties.

"Penoplex 45"(density 35-47 kg/m 3) - insulation of road surfaces, in particular runways, to prevent them from frost heaving of the soil and destruction of the top layer of the road surface. It is also widely used for insulating roofs in use, on which there are pedestrian areas and various areas, including parking lots.

"Penoplex COMFORT"(density 25-35 kg/m3) - a brand of thermal insulation boards used in housing construction (private residential buildings, insulation of apartment walls, as well as loggias and balconies).

Penoplex installation

Insulation of external walls with penoplex is carried out in several stages.

1. Preparatory work consist in preparing the walls for insulation, namely cleaning them from dirt, dust, old finishing materials, paint coatings. It is recommended to level the walls using plaster mixture(in case of obvious unevenness of the walls) and treat with an antifungal compound.
2. Gluing Penoplex boards carried out using special adhesive compositions on the dry surface of the walls. The adhesive is applied directly to the insulating board.
3. Mechanical fastening made using dowels, based on 4 pcs. us 2 , after gluing the boards with glue. Along the perimeter of the windows, doorways and at the corners of the building the number of dowels increases - 6-8 pcs. us 2 .
4. Apply on top of insulation slabs plaster composition . For better adhesion of the plaster to the insulation, it is recommended to create roughness on the surface of the slabs using a carriage brush. A reinforcing polymer mesh is “recessed” into the first plaster layer. Next, a second layer of plaster is applied, after which dries, the walls are painted in the desired color.
5. Instead of plaster, it is possible to finish the walls siding, wood, as well as application mounted systems for which a frame is pre-arranged.

If it is impossible to insulate from the outside, then, if necessary, insulate the walls from the inside. The work is carried out in a similar way, but a foiled polyethylene film is installed on top of the penoplex as a vapor barrier, then gypsum plasterboard sheets are attached, onto which wallpaper can later be glued. The lathing for hanging drywall is attached with dowels to the wall through the insulation.

Work on insulation of balconies and loggias is carried out in the same way.. The joints between the plates are taped. After installing a vapor barrier with PE foil film, we also glue the joints with tape - we create a kind of thermos.

If for finishing If you decide to use drywall, then you need to choose moisture-resistant gypsum board sheets. In addition to the walls, it is also necessary to insulate the loggia floor.

Thermal insulation of roofsproduced either at the construction stage or during the reconstruction process, for example, when converting a cold attic into a living space.

1. roofing material
2. sheathing
3. 3vapor-permeable moisture-resistant membrane
4. penoplex insulation
5. interior lining
6. truss structure

In the first case, the insulation is laid on top of the rafters in a checkerboard pattern. A vapor-permeable membrane is spread over the penoplex. Expanded polystyrene is fixed with longitudinal slats with a thickness of at least 40 mm to ensure ventilation between the insulation and roofing material, in increments of 300 mm.

Penoplex compared to its analogue - polystyrene foam - has a higher cost, but significantly exceeds it in strength. It is ideal for plastering systems.

If you are still in doubt about which material to choose for insulating the structures of your home, then read consumer reviews, perhaps this will help you decide.

Do Vacation home Every owner strives to be comfortable throughout the year. Comfort consists of several components, but largely depends on insulation. One of the most popular insulation materials present on the construction market is penoplex insulation. This slab insulation, although it has almost a century-old history, does not lose its position, since it has a number of advantages over other materials.

A little history

A brief history of the emergence of extruded polystyrene foam (the official name of penoplex) is as follows:

1941. Like many other useful things, the material was originally developed for the needs of the army (in this case, the US Navy). This year, The Dow Chemical Company received a patent for new development, and already in 1942 it established large-scale deliveries. The moisture-resistant material with excellent heat-insulating properties was used in the production of boats and life rafts.

1952. After the war, the Americans continued to use penoplex, its use expanded significantly, first in the refrigeration industry, and then in construction.

1963 G. Extruded polystyrene foam has spread throughout Europe and has since occupied a stable niche in the insulation market.

1998. Extruded polystyrene foam began to be produced in Russia (in the Leningrad region) under the Penoplex trademark and was adequately appreciated by builders.

About production technology

Extruded polystyrene foam (penoplex, XPS) is a related material to ordinary polystyrene foam, commonly known as polystyrene foam. Penoplex is also made from polystyrene granules, but the technological chain has a different form:

Preparing the mixture. The granules are loaded into a mixer, where they melt under the influence of elevated temperature, and after introducing a foaming agent under pressure, they form the desired homogeneous structure.

Molding. The foam mixture passes through extruders (forming holes), is cooled and cut into slabs.

Result. Structure extruded polystyrene foam forms many small cells filled with air. Due to the fact that the cells are closed, the material acquires the properties of an excellent heat insulator. The color of the slabs is yellow-orange, less often blue.

Advantages and disadvantages of penoplex

Like anyone building material, penoplex has its own strengths and weak sides. Knowledge of the characteristics of the material will allow you to use it with maximum efficiency; in number positive characteristics includes the following parameters:

Low thermal conductivity. The thermal conductivity coefficient does not exceed 0.03 W/mºK, which indicates high degree thermal insulation.

Low water absorption. 0.5% by volume per month.

High compressive and flexural strength– 0.27 MPa. This property allows the slabs to be used not only as insulation, but also as a building material that is not subject to structural cracking.

Light weight. Due to its low density, the material does not create a load on the supporting elements.

Wide operating range. The material does not lose properties in the range from -50 to +75°C.

Durability. The service life is 30-50 years.

Easy installation.

In order for penoplex to bring the expected benefits, you should also remember the disadvantages (and take them into account):

Low vapor permeability. The indicator is worse than that of polystyrene foam, which makes you think about a good ventilation system.

Flammability. Belongs to class G3-G4 (normally and highly flammable substances).

Environmental friendliness. The material is safe for health if it does not contain harmful impurities. Existing variety– self-extinguishing polystyrene foam, impregnated with fire retardant and can have Negative influence for a person.

Extremely low noise insulation.

UV instability. It is destroyed by exposure to sunlight and needs protection during storage.

Instability to a number of organic solvents and other substances. These include gasoline, diesel fuel, oil paints, polyester resins, aromatic hydrocarbons, esters.

Types and sizes of thermal insulation boards

Manufacturers produce foam sheets, the size and specific density of which are indicated on the packaging and determine the limits of use of the material. The following types of slabs are available:

For walls. Plates with a density of 25-32 kg/m 3 are used to insulate the facade (due to the low vapor permeability of the material, additional vapor barrier of the interior will be required). When externally insulating a non-residential building, a vapor barrier is not required. Finally, you can plaster over a metal mesh, or cladding with a façade material of your choice (lining, siding, ceramic tiles).

For roofing. It is known that up to 20% of heat is lost through a poorly insulated roof. Penoplex "Roof" is designed specifically for thermal insulation of roofs, pitched or flat. Lightweight and moisture-resistant slabs with a density of 28-33 kg/m 3 are simply joined together without the formation of cold bridges. The material is rigid enough to withstand significant installation and operating loads; it is equipped with a groove that ensures a tight fit.

Packaging marking Source samodelino.ru

For the foundation. The increased density of the slabs (29-33 kg/m 3) allows them to be used for arranging the foundation, ground floor, garden paths, insulation of the septic tank and utilities.

Penoplex "Comfort". Sheets with a density of 25-35 kg/m 3 have an L-shaped edge, so they can be installed without any problems. Thermal insulation boards are widely used in private housing construction (including insulation of bathhouses, saunas and swimming pools), as well as for high-quality insulation apartments (especially loggias and balconies).

Penoplex 45 (GEO). High-density (35-47 kg/m3) material, suitable for use under constant heavy loads. It is used for insulation of runways, roads (roads and railways), exploited roofs, parking lots and pedestrian areas.

There are calculation tables for different regions, which determine the choice of penoplex sheets; the thickness in them is a key indicator. The most commonly used plates are 20-100 mm thick. Depending on the brand, the length varies between 1200-2400 mm, the width is always the same - 600 mm. The number of slabs in a package can vary from 4 to 18 pieces.

Methods for attaching penoplex

In modern suburban construction Installation of penoplex boards is carried out in three ways:

Using an adhesive composition. A universal method suitable for insulating a large surface, facade or basement, followed by plastering.

Using fasteners. If a significant load on the insulation layer is not expected, the sheets are secured using plastic disc dowels. The method is suitable for insulating a basement or loggia.

Using polyurethane foam . The advantage of polyurethane foam is its high adhesion (adhesion to the surface) important role when insulating the floor, attic floor and walls.

Insulation of the facade: stages of installing slabs with glue

The process of insulating a façade with penoplex slabs is as follows:

Surface preparation. Contaminants and the old cladding layer are removed from the working base. If there are mold stains, they are treated separately (disinfected copper sulfate). If necessary, the surface is leveled and primed.

Installation. The sheets are glued in rows, from bottom to top, with bandaging (offset) of the seams. The adhesive composition is applied to the foam sheet in two crosswise lines. In an alternative method, if the glue is applied to the work surface, it is done in a continuous layer. Each slab is pressed against the wall, its position is checked by level.

Sheet cutting. The obvious method, breaking the sheet, is not suitable, as it produces an extremely sloppy, crumbling line and irreversibly damages the part. A regular hacksaw gives a better, but also not perfect, edge. The best results are obtained when using electric jigsaw. If you need a sheet of a more complex (curly) shape, you often use a heated tungsten wire (which requires some skill) or a thermal cutter. Laser cutting carried out in a workshop environment and allows you to obtain neat and accurate parts (templates or decorative elements).

Additional fastening. It is necessary if the adhesive method has shown imperfect results and the slabs are moving away from the base. In this case, self-tapping screws installed in the corners of the sheets will help. Alternative way– thermal dowels with wide caps, which are installed in the seam between the sheets and fix several elements at the same time.

Preparing penoplex for plastering. The heat insulator layer is covered with glue, onto which a metal mesh base is fixed (embedded), and the top is additionally leveled with glue.

Finishing work. After the glue on the reinforcing mesh has dried, they proceed to the finishing cladding with plaster.

How not to lose money

If designers and builders do not take into account the physical and chemical characteristics of penoplex, its strength and thermal characteristics deteriorate long before the end of its service life, which leads to a decrease in the thermal efficiency of the house. Some of the most common errors include the following solutions:

Use of material with a density lower than technologically justified. Penoplex, like any polymer, is oxidized by atmospheric oxygen. The rate of oxidation (change in chemical structure and deterioration in performance properties) depends on the density of the material. The use of slabs with a lower density (an understandable desire to save money) deteriorates the thermal protection of the structure 2-3 times faster, and this is noticeable already in the first 7-10 years of operation.

Internal insulation Source chebaki.ru

Use of incompatible materials. Plates made of extruded polystyrene foam will deteriorate at an accelerated rate if substances that are dangerous to the structure of the penoplex (for example, oil-based paints containing volatile hydrocarbons) are used during construction.

Ignorance of labeling features. An inexperienced person, seeing the words “Mark 25” on the packaging, makes a logical, in his opinion, conclusion that inside there are slabs with a density of 25 kg/m 3. But in technical conditions This designates material with a density from 15.1 to 25.0 kg/m3. Some manufacturers, caring for maximum profits, supply penoplex of the lowest density (15.1 kg/m2) under this brand 3 , density of packaging plastic). The result of the substitution soon appears on the “insulated” façade – with damp spots and mold.

Improper insulation. Improper insulation leaves air gap between the wall and the slab material. The structure becomes inhomogeneous, the dew point shifts into the gap. Condensation is inevitably absorbed into a denser material (wall), and thermal efficiency drops, sometimes significantly.

Conclusion

Each owner, investing significant sums in the construction country house, expects that housing will be long years, serve faithfully for decades. Reliability of walls and internal comfort to a large extent depend on properly carried out insulation. Competent use of penoplex will make significant savings in thermal energy ( main goal any insulation), and, therefore, the family budget.

When it comes to home, the first associations, in addition to coziness, are also comfort and warmth. Therefore, insulation materials of all kinds and made from various raw materials will not cease to arouse increased interest among consumers. Application of this material is becoming a sustainable trend, so it is worth familiarizing yourself in more detail with the characteristics of penoplex and methods of its installation.

Penoplex plates

Penoplex is foamed polystyrene produced 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, no larger than 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 pressed through an extruder. Foaming agents (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, once the manufacturing process is completed, all these auxiliary additives are replaced by air from the environment.

Penoplex photo

As a result, a thermal insulation product is obtained with good performance for materials of this group intended to conserve heat. These include:

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

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

Plates of material are packaged in film that protects them from the penetration of sunlight. The original packaging allows you to store polystyrene foam on outdoors. But, despite the plastic film, it is worth providing them with additional protection from UF rays, which can damage upper layer insulation. No other special conditions for storage are required, because foamed polystyrene is not afraid of humidity and temperature changes, the main thing is to control the safety of the packaging.

Types of penoplex and areas of application

The 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. Belongs to the G4 flammability group. Applicable in the following areas:
• insulation of foundations in horizontal and vertical directions, as well as roofs on a reinforced concrete base;

• when laying pool bowls, utility networks, and insulating temperature bridges;
• insulation of various underground structures - fire wells, storage tanks;
• during the construction of local water supply and sewerage systems in private houses, provided that communications are laid in the freezing zone;
• Penoplex slabs of class 31 C are also used when installing shallow foundations.
• Penoplex 35 produced with a density from 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 both corrugated and pitched), cold bridges and utility 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, storage facilities, freezers and ice arenas.

Separately, it is worth mentioning that at the time of production of this brand of polystyrene foam, special additives are added to the feedstock at the mixing stage to increase the resistance of the insulation to combustion. Such slabs burn poorly and prevent the fire from spreading further, and when smoldering, they release only two types of gases (carbon dioxide and carbon monoxide), unlike a number of other insulating materials that “release” a whole complex of harmful substances and compounds.

• Penoplex 45 C has a density of 35 to 40 kg/m³. Flammability class - G4. It is used for insulating foundations, roofs and floors exposed to load.

• Penoplex 45. Density indicator from 38 to 45 kg/m³, flammability group G4. The scope of application coincides with the above types of material. In addition, it is used to insulate 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 allows it to be used in the construction of airfield runways 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 for use only in the temperature range from -50°C to +75°C. Compliance with operating temperatures guarantees that the material will retain its properties. specifications. If this condition is violated, the penoplex slabs may become deformed and lose some 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 polystyrene.

• Penoplex extruded polystyrene foam boards have good chemical resistance to most substances and materials used in construction. These include:
  • wood preservatives (only for water based, containing no solvents);
  • bitumen mixtures;
  • cement;
  • lime.
• Substances containing a solvent can have a destructive effect on penoplex, leading to its softening and, as a result, shrinkage of the material slabs. The group of substances with which contact should be avoided when working with expanded polystyrene foam includes:
  • paint thinners;
  • coal tar and its derivatives;
  • solvents (acetone, petroleum toluene, ethyl acetate).

• Penoplex slabs do not pose a threat to human health and are not hazardous to the environment, which is confirmed by research and certificates for these products.
• Penoplex material can be characterized by several other indicators.
• Low thermal conductivity (thermal conductivity coefficient at 20-30°C - 0.030 W/(m×°C)). The indicator for this evaluation criterion is significantly lower compared to the average values ​​of most other insulation materials.
• Tests of the slabs for water absorption showed that the sample immersed in water absorbed moisture for the first 10 days. And in a month it 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 penoplex makes it possible to use it in conditions high humidity without changing thermal conductivity. That is, foamed polystyrene can be used without additional waterproofing, unless certain environmental conditions require it.
• In terms of vapor permeability, a 2 cm thick penoplex slab is equivalent to a layer of roofing felt.
• It is able to retain its properties even with numerous frosts and subsequent thawings. Their service life is at least 50 years.
• The extrusion method used in the production of plates results in a uniform and dense structure. finished products. This gives the penoplex stable high strength for compression.
• Many have already appreciated the simplicity and 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.

DIY penoplex insulation

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

Installation of penoplex from inside the building

• Preparatory work. Standard procedure for all types of construction and finishing works is also observed in this case. Be sure to completely remove all traces of previous surface finishing and paints and varnishes. You will have to get rid of fungus and mold with a special composition, and then it is recommended to carry out “sanitation” with any purchased products that have bactericidal properties. The surface should be as leveled and primed as possible.
• Assembly of the base profile. The installation of this special design is necessary for a more even and tight fit of the polystyrene foam boards. The profile will also protect the insulation from external influences. Its fastening is carried out using dowel-nails, and lining washers will help ensure a tight fit of the canvas to the surface to be finished. An important requirement is the correspondence of the width of the base profile to the thickness of the penoplex slab. Using joining plates, adjacent structural elements are joined together. Be sure to leave a distance of approximately 2 mm between them.

• Installation of insulation boards. A layer of glue is applied to the penoplex along the entire perimeter of the material and in the center. Many professional builders advise not to save money, to coat well adhesive composition the whole stove. After this, the foamed polystyrene is pressed against the profile. The protruding excess glue is removed, and it is better to fill small gaps with inserts from pieces of polystyrene foam that were left during trimming. The issue of using polyurethane 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 the formation of cracks.
• Final consolidation. After the glue has dried (about 3 days), work continues. With the help of dowels, the final fastening of the material takes place. Hardware is located in the middle of the slab and along its perimeter, but in such a way as to connect adjacent sheets.

• Insulating walls on the living room side 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 cladding is outside.

How to insulate the outside of a building with penoplex

• This insulation method will require material with a thickness of 80 to 100 mm. The stages are similar, but there are some nuances.
• The facade is leveled, cracks are sealed and the wall is primed as a “final” treatment.
• Penoplex is glued as described above and attached to dowels using the same principle.
• If you plan to finish with plaster, then as preparatory stage you just need to stick on the reinforced mesh.
• If the final finishing 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 foamed polystyrene.

As you can easily see, all the work is quite easy to do yourself. The situation is more complicated folds with insulation on the outside of apartments in a multi-storey building. In this case, you cannot do without the services of industrial climbers.

Thermal insulation of the floor using penoplex

• One of the ways is insulation on the joists. This option is suitable for wooden houses installed on columnar foundation. In this case, there are slabs of extruded polystyrene foam in the spaces between the joists.
• First, the old floorboards are dismantled if the insulation process is taking place in an already residential area, and not at the construction stage. If you plan to return them to their place, then this is a good reason to examine each one for integrity and treat it with impregnation to protect it from rotting.
• Installation of new logs begins with the outermost beam, leveling it, and then the beam is attached from the opposite end. Now, having stretched the fishing line between them, you can use it as a guide to install the remaining logs, not forgetting to make sure that they are positioned strictly in a horizontal plane.
• A layer of waterproofing is attached to the assembled beams using construction stapler. The edges of the film should reach the middle of each guide.
• Penoplex slabs 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 polyurethane foam that will be used to process the seams does not include toluene, which can have a destructive effect on the material.
• The final fastening of the penoplex occurs with the help of dowels, and the boards are mounted again on top.

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

• First, an even layer of gravel 30-40 cm high is poured onto the ground. It is thoroughly compacted, and sand is laid as a second layer (about 10 cm). The pressing procedure is repeated with him too. A reinforcement frame is assembled and filled with concrete. After the screed has dried, the actual insulation of the surface begins.
• Waterproofing is easiest done from dense polyethylene.

• Penoplex slabs, as in the previous version, are arranged in a checkerboard pattern. A reinforcing mesh is stretched from above.
• After attaching the polystyrene foam, the screed is refilled. It is allowed to dry and the floor covering is laid.

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

Extruded polystyrene foam (penoplex) has established itself as a good and convenient thermal insulation material. However, before starting construction work with penoplex, you need to find out how much material is required. This thermal insulation material is produced in slabs various sizes and thickness.

No one doubts the need to insulate houses located in cold regions. Experts considered that the loss of thermal energy through walls and other elements not protected from low temperatures building structure reach thirty-five percent.

The use of insulation reduces ineffective heat consumption, which allows the use of less powerful heating equipment and significantly reduces the cost of heating residential premises. For these purposes, penoplex is widely used, the technical characteristics of which are optimal. This material is an extruded type of foam. Outwardly, it is similar to polystyrene foam, but is made using a different technology.

"Penoplex" is suitable for insulating all parts of the house

Special properties of extruded polystyrene foam "Penoplex"

Penoplex acquires unique performance qualities as a result of the peculiarities of its manufacture. At the beginning of the production process, a homogeneous liquid melt of polystyrene granules is obtained by heating. Then a foaming agent is introduced into it under high pressure, which is carbon dioxide. It is evenly distributed throughout the entire volume of the melt.

On final stage Foamed polystyrene undergoes a process of extrusion or extrusion through calibrated holes. This achieves special performance properties of extruded polystyrene foam that are not available to other insulation materials.

When the finished substance cools, carbon dioxide is replaced by air from the environment, and completely closed cells with a diameter of about eight hundredths of a millimeter are formed. As a result of the described transformations of the material, the technical characteristics of penoplex become unique. Most important characteristic thermal insulation materials are thermal conductivity, and penoplex has one of the best parameters.

Penoplex production line

Quite low thermal conductivity coefficient

The low thermal conductivity coefficient of penoplex, amounting to 0.03 W*m*0C, is explained by its cellular structure. The parameter practically does not change over time, its fluctuations are extremely insignificant and range from one to three hundredths of the original value. In terms of this operational parameter, penoplex is superior to polystyrene foam and other heat insulators, for example, mineral wool. The thermal conductivity of penoplex in comparison with them is one of the lowest.

If you evaluate thermal insulation properties penoplex in comparison with brick, then insulation with a thickness of 50 mm corresponds to a brick wall with a thickness of 925 mm, and a 30 mm material will replace a 555 mm wall.

Almost does not absorb water

The hygroscopicity of the product is amazing: it practically does not absorb water. A slab completely placed in water absorbs moisture to only six-tenths of a percent of its volume over the course of a month. All of it is absorbed in the first ten days, then the process stops completely. Moisture penetrates only into the top layer of the extruded foam board.

"Penoplex" does not favor water

Almost no steam escapes

A sheet 20 mm thick practically does not allow water vapor to pass through, much less penoplex 50 mm or 100 mm thick. When finishing surfaces with penoplex, no additional vapor barrier is required. Vapor permeability practically does not differ in its characteristics from roofing felt. In some cases, for example, when finishing walls from the inside, this performance property is rather a disadvantage, since it does not allow the walls to breathe.

Has high compressive strength

The high compressive strength, ranging from two hundred to seven hundred pascals, depending on the application, is due to the homogeneity of the structure. Evenly distributed tiny cells improve the strength properties of the material. It does not change its size when squeezed. This allows the material to be used for thermal insulation of floors and other surfaces that experience heavy loads.

The Penoplex bulldozer will not crush

Processing and installing insulation is easy and simple

Installing and processing extruded foam is easy and simple. You can cut it using an ordinary sharpened knife. The slabs are lightweight, so working with them does not require significant physical effort. Installation can be carried out in adverse weather conditions: snow or rain.

Chemically - practically passive

Expanded polystyrene, from which penoplex is made, does not react chemically with most substances used in carrying out construction work. The following chemically aggressive substances do not have a negative effect on it:

• acids and alkalis;
• bleaching powder;
• carbon dioxide and oxygen;
• ammonia, propane, butane;
• cement mortars;
• oils and alcohols.

Some organic solvents can soften and disrupt the shape of the insulation. These include: diesel fuel and gasoline, aromatic hydrocarbons (such as benzene and toluene), oil paints and tar, acetone, ethers. It is worth noting the high biological stability of the material: it does not rot or decompose.

Environmentalists have no questions about the material

If you follow technological standards during production, penoplex is environmentally friendly pure material, environmentalists have no questions for him. You can work with an insulator without tools personal protection. However, one must take into account its artificial origin and understand that chemical components can evaporate under the influence of certain factors, for example, during prolonged heating by direct sunlight.

Fire resistance is not ideal at all

Exposure to an open flame causes the polystyrene foam to ignite. The flammability class varies depending on the purpose of use. Impregnation of this material with compositions that prevent fire does not lead to its complete fire safety. When exposed to high temperatures, the material will melt, turning into a fluid mass that releases extremely toxic and acrid smoke.

Visual characteristics of the flammability of insulation materials

The overall result is that it lasts long and reliably

The service life of insulation is determined by the number of cycles of negative and positive temperatures that the material can withstand without destruction. This parameter shows the ability of the insulator to withstand seasonal changes in external temperatures.

Tests have shown that extruded polystyrene foam does not lose its performance characteristics over fifty defrosting cycles.

This value determines the service life of at least fifty years. During research, the material was exposed to various negative environmental influences, such as strong wind and rain, frost and ultraviolet radiation. In all cases, he showed himself worthy.

Technical characteristics of various types of material

Foam board is widely used for thermal insulation of building structure elements. As a result, depending on the purpose of use, the technical characteristics differ individual species material. Slabs are produced in thicknesses of 20, 30, 50 and 100 mm, of varying strength and flammability. For example, Penoplex 31 has low compressive strength, so it is used mainly for insulating pipelines and containers, and there are materials that are used for insulating airfield runways.

"Penoplex Wall" - for wall insulation

Penoplex Wall is used to insulate the walls of houses. The name appeared not so long ago; previously this material was labeled as Penoplex 31 with fire retardants. Its use for thermal insulation of plinths, building facades, internal and external walls of houses gives good results. At the same time, the walls are sheathed from the inside only if for some reason it is impossible to lay insulation on the outside. Summary of material characteristics are given in the table below.
