Extruded polystyrene foam Penoplex technical characteristics. Overall dimensions of penoplex slabs depending on its brand. Insulation brand "Foundation" - parameters and properties
Insulation Penoplex technical specifications and properties - penoplex is very similar in properties to expanded polystyrene, but is a new development with a completely different production technology. Due to its specificity, Penoplex is very effective in matters of wall insulation.
Penoplex insulation of building walls and balconies
Specifics of production and special properties of building materials
In the production of this insulation, a special extrusion plant is used, in which polystyrene granules can be processed under high pressure and temperature. In order for the transformation process to start, a special substance is added there to serve as a catalyst for the reaction. Often, carbon dioxide and freon in light form are used as such a catalyst.
Ready mix It turns out fluffy and resembles peaks of whipped cream. Through special hole apparatus, the resulting substance flows outside, where the freon is replaced by air and evaporates. This material has fairly small pores - up to 0.1 - 0.2 mm, which increases its power and heat-insulating properties. It is worth noting that all cells are located evenly and isolated from the external environment.
Penoplex technical characteristics have the following:
- Minimum moisture absorption. Typically, water does not have access to the internal cells of the insulation. This has a beneficial effect on the thermal insulation capabilities. In addition, this quality makes it possible to use Penoplex in an environment with high humidity or the presence of seasonal rains for external use.
- Low thermal conductivity coefficient. Even compared to others heat-insulating materials it is significantly lower and amounts to only 0.03 W*m*°C. Thermal conductivity does not depend even on changes in air humidity in the space used. Thanks to this property, insulation of this brand can be used in attics, foundations, etc. without using an additional layer to protect against moisture.
- Low vapor permeability. This shows its high durability and resistance to the penetration of gases and steam into the material. This feature characteristic of all materials made by extrusion.
Penoplex service life
- Elevated service life. It can withstand a large number of freezing and thawing cycles. According to the experiments of the NIISF Institute, their minimum service life is 50 years or even more. This takes into account the influence of atmospheric phenomena.
- Increased compressive strength. Due to the presence of tiny cells of the same size and evenly laid out throughout the entire space of the material, the latter increases its resistance to mechanical stress. Even under heavy loads, its dimensions will not change or become compacted.
- Easy to assemble and install. Also easy to process. Despite its strength characteristics, during installation work it is convenient to cut it into the necessary blocks using a regular knife. Without much effort, you can quickly and efficiently cover your walls with the insulation in question, without fear of snow, rain and frost.
- Excellent resistance to aggressive Penoplex chemicals. This concerns chemical mixtures, which are used in construction work. They do not react in any way with the insulation. However, there is an exception - organic-based solvents, which can soften the slabs or even dissolve completely. Among the substances that can react are toluene, xylene, benzene, formaldehyde, formaldehyde, ketones, ethers, gasoline and other fuels, coal tar, oil paints. However, the insulation is resistant to acids, salts, alkalis, alcohols and alcohol paints, mortars based on cement and concrete, water, freons, oils, paraffins, etc.
- Environmental friendliness and safety for human health and environment. Freons that are used in the manufacture of these plates are not dangerous, they do not burn and do not emit toxic substances.
Penoplex may also have technical characteristics such as excellent resistance to biological manifestations. Such slabs do not rot or decompose, they do not mold, which also makes them advantageous for use.

Installation conditions for Penoplex to maintain technical characteristics
To ensure a constant shape and size of Penoplex, the characteristics of which must remain unchanged, it is necessary to install and process in the right conditions. This applies to humidity and air temperature. To do this you need to endure permissible temperature air, at which this type insulation can function normally during long-term use.
Insulation of a balcony with penoplex
If the heating is excessive, it can not only change its shape and size. The technical characteristics of Penoplex are also violated. Because of this, it can not only begin to melt, but also ignite. Nevertheless, this disadvantage apply not only to a specific type, but also to all foam materials.
Product range
Depending on its characteristics, Penoplex is divided into several types depending on its application:
- Insulation of house walls. With its help, you can insulate the basement, building facades, partitions, as well as external and internal (if external insulation is not possible) walls.
- Foundation insulation. It has increased resistance to stress. It is also used for garden paths, insulation of floors and plinths.
- For the roof as well attic space roofs with ventilation.
- Comfort is an option that is perfect for insulating balconies, as well as mansions in general. It is also used for insulation of saunas and baths.
- For inversion type roofs, as well as thermal insulation of highways, railway etc. In this case, expanded polystyrene is used, the technical characteristics of which are several times higher than those of other types of insulation. This is especially true for resistance to various loads.
Information to note : , .
A person’s comfortable living in a new home depends on many factors, and thermal insulation plays not the least role in this matter. The modern market offers a huge number of insulation materials, differing in characteristics and cost. The most effective, as practice and consumer reviews have shown, is Penoplex 30 mm.
What is it?
Penoplex (extruded polystyrene foam) was first introduced to the public in the United States more than 50 years ago. The material quickly gained the trust of customers due to its low thermal conductivity and affordable price.
At the creation stage of this product under pressure and high temperature polystyrene granules are pressed, using a special catalytic substance carbon dioxide and light freon to foam the mass. The finished mixture resembles thick confectionery cream. After mixing and foaming, all the liquid passes through special nozzles of the extrusion unit and comes out. Freon evaporates, and the resulting voids are filled with air.
Thanks to such a complex technological process finished product It turns out to be finely porous, which means it is durable and light.
All air cells are isolated from each other, and their diameter does not exceed 0.1–0.2 mm. The standard size of the Penoplex 30 mm panel is 585x1185 mm. The dimensions of the plates of this product affect the number of sheets in the package. This criterion also affects how many m² of thermal insulation is contained in one pack.
As a rule, one package of Penoplex is enough to insulate 10.08 square meters of surface.
Advantages and Disadvantages
Thermal insulation of the new generation "Penoplex" 30 mm in its technical characteristics is in many ways superior to the previously popular mineral wool and polystyrene foam.
It comes with excellent benefits.
- Excellent thermal insulation. According to experts, Penoplex 30 mm replaces about 750 mm brickwork. The low thermal conductivity of the material allows you to significantly save money, because when working on thermal insulation, you can use a thinner layer of Penoplex than the same foam.
- High strength. This property allows polystyrene foam boards to cope even with large vertical loads. Therefore, Penoplex 30 mm can be purchased for cladding plinths, foundations, and external walls.
- Excellent sound insulation. Extruded polystyrene foam can be used to soundproof rooms. With its help, they can successfully equip home studios or get rid of annoying street noise. nervous system. An extrusion partition “eats” up to 41 dB, giving the home long-awaited peace and quiet.
- Moisture resistance. The less the insulation allows steam to pass through and absorbs moisture, the better it copes with its functions. Penoplex, 30 mm thick, has zero moisture absorption, so it works on walls like a thermos.
- Light weight. Penoplex 30 mm slabs are lightweight, which allows them to be quickly installed and save on transportation.
- Absolute safety. Extruded polystyrene foam is non-toxic, has no chemical odor, and is therefore harmless to human health and the environment. Even children's toys are produced from some brands of extrusion. Harmful impurities such as soot, slag, freon are absent in the product, which means we can talk about the environmental friendliness of the slabs.
- Long service life. Low quality polystyrene crumbles at the slightest impact. Even the most expensive mineral wool begins to settle and wrinkle over the years, and 30 mm Penoplex insulation, even after 50 years of service, will not lose its original characteristics.
- Low thermal conductivity. Thanks to microcells, the extruded product is a material with low thermal conductivity. In a house with such insulation it will not be hot in the summer, and it will not be cold in the cold season.
- Temperature range, at which you can work with Penoplex 30 mm is from -50 to +75ºС.
- Wide range of applications.
The material is lightweight and easy to install.
The only drawback of extruded polystyrene foam is that this product does not tolerate the influence of organic solvents, for example, acetone. Similar aggressive chemicals soften the slabs, destroy their shape and even completely dissolve.
Scope of application
Thermal insulation boards "Penoplex" 30 mm are used for thermal insulation of walls, roofs, foundations, plinths and floors in private properties. And also wide application The extrusion product was also found in the insulation of balconies and loggias in city high-rise buildings.
Penoplex 30 mm is used to insulate enclosing structures, garages and other types of outbuildings.
When laying slabs between work surface The insulation material and the facing surface do not form “cold bridges”, which creates an optimal microclimate inside the living space. The ambient temperature is always pleasant for a person to be in under any weather conditions.
Due to its high strength, Penoplex 30 mm can withstand high loads both in horizontal and vertical positions.
In any condition, it does not deform during facing work. Boards of extruded material do not absorb moisture, so the products are successfully used for cladding baths and saunas, wine cellars, swimming pools and other rooms where the humidity level is constantly high. If it is necessary to insulate the apartment, make repairs in country house or waterproof the foundation, you don’t need to overpay by buying Penoplex of more expensive series.
For interior work 30 mm Penoplex extrusion is quite sufficient. The cost of packaging this product will be significantly lower compared to the same “Penoplex” 100 mm, in addition, the smaller thickness will not “eat” usable area housing.
A Penoplex insulation board with a thickness of 30 will be useful when arranging:
- "warm floor" systems;
- waterproofing the base and foundation;
- any type of roof and ceiling;
- partitions or “well” masonry walls;
- garden paths.
Stamps
On modern market You can find several series of Penoplex 30 mm.
- "Roof". The main purpose is to install a thermal insulation layer for any type of roof. The main advantage of these plates is their high strength and the presence of antiprenes (anti-flammable impurities) in the composition.
- "Warp". Used for internal and external cladding insulating layer of enclosing structures. If there are no special load requirements for this series, you can safely use it to insulate walls, floors, roofs, and plinths.
- "Facade". Counts the best option for insulation of partitions, walls and facade surfaces. The advantage of these plates is their ability to self-extinguish and have a rough surface, which means better adhesion of glue and plaster mixture.
- "Comfort". This insulating material, according to experts, is suitable for almost any need: insulation of loggias and balconies, walls, flooring, foundation insulation, engineering communications and even garden paths.
Price
Price thermal insulation material“Penoplex” 30 mm depends on who produced it, on the dealer selling the boards on the market, on the selected series and sheet size. A package of 30 mm thick insulation boards, consisting of 12 sheets, will cost buyers 950 rubles and more.
The cost may be lower if you buy Penoplex in bulk and in large quantities. Penoplex is sold only in packages. This makes the process of transporting it easier. Each package of 30 mm thick insulation contains up to 16 slabs (the number depends on the size of the product). As a rule, the package contains a table for calculations required quantity slabs

Below is a list of frequently asked questions and answers related to PENOPLEX ® thermal insulation:
Differences between PENOPLEX ® and non-pressed polystyrene foam (PSB)
PENOPLEX ® boards and expanded polystyrene (PSB) differ in their production technology. Pressless polystyrene foam is created by “steaming” microgranules with water vapor in a special form and expanding them under the influence of temperature. Thermal insulation PENOPLEX ® is made by mixing polystyrene granules at elevated temperature and pressure with the introduction of a foaming agent and subsequent extrusion from the extruder. That is why PENOPLEX ® expanded polystyrene is called extruded. Also, thanks to the production technology using this technology, PENOPLEX ® receives a closed, fine-porous structure, which in turn ensures high strength, almost zero water absorption, as a result - biostability and the highest durability of PENOPLEX ® boards. An important factor There is also a lower thermal conductivity of PENOPLEX ® compared to pressless polystyrene foam (PSB), which makes it possible to reduce the thickness of the required thermal insulation by approximately 30%.
Which insulation to choose: PENOPLEX ® or mineral (stone) wool?
What is better PENOPLEX ® or mineral wool? This is a question that arises quite often among private developers. Each of these materials has its advantages. For example, PENOPLEX ® is practically indispensable in loaded structures and humid environments, while mineral wool performs better in sound insulation. In addition, some types mineral wool have more low price, but this advantage often comes to naught due to the low quality of such wool, as a result - large shrinkage, as well as the need for greater thickness of thermal insulation.
PENOPLEX ® is distinguished from mineral wool by a number of characteristics:
- more low coefficient thermal conductivity.
- high compressive strength
- absolute moisture resistance (PENOPLEX ® does not absorb water, due to which it retains its thermal insulation properties throughout its entire service life).
- absolute biostability (PENOPLEX ® is not a matrix for the development of bacteria, mold and other microorganisms).
- ease of installation (PENOPLEX ® does not require special means protection when working with it).
What is the density of PENOPLEX ®?
The density of PENOPLEX ® boards for private use ranges from 23 to 35 kg/m3. For the professional segment, this figure can reach up to 45 kg/m3. It is important to understand that the density of PENOPLEX ® is not a key factor in determining the scope of application of the material. A more important characteristic is compressive strength. The strength characteristics of PENOPLEX ® vary over a wider range. The minimum compressive strength at 10% deformation for PENOPLEX ® slabs is 0.12 MPa; such slabs are used for non-load-bearing structures (for example, for wall insulation). More high performance The compressive strength of slabs designed for insulating foundations is 0.3 MPa, since it is these structures that bear the main loads from the building. PENOLEX ® grades intended for road construction and structures with increased loads can have a strength of 0.50 MPa and higher.
A wide range of characteristics allows the use of PENOPLEX ® slabs for insulation of almost any structures, both in cottage and low-rise buildings, as well as in industrial and civil construction.
What is the melting point of PENOPLEX?
The temperature range for use of PENOPLEX ® boards is from -70 to +75 degrees Celsius, which allows the use of this material in any climatic zones.
At temperatures above 75 degrees Celsius PENOPLEX ® can change its mechanical properties towards decreasing the strength of the material.
How many bricks does PENOPLEX ® replace?
If we compare materials in terms of thermal insulation properties, a PENOPLEX ® slab with a thickness of 50 mm (λ = 0.034 W/m2°C) will replace 1280 mm of masonry on a thermal insulating mortar made of solid single brick (λ = 0.82 W/m2°C). (According to GOST 530-2012 Ceramic brick and stone. General technical specifications. Table D.1 - Thermal characteristics continuous (conditional) masonry).
On average thermal insulation properties 1 cm PENOPLEX ® replaces 25 cm of brickwork, but remember - for everyone a separate type bricks (silicate, ceramic, clinker) this comparison will be different.
No construction today can be completed without the use of insulation. For each type of task, they try to choose one that will last as long as possible. One of the leaders is penoplex. Penoplex 35 g/m 3 is even used for insulation of routes. But why do many people prefer to use this particular material? Understanding its features, as well as the sizes of sheets that are commercially available, will help you understand this.
What kind of insulation
In fact, Penoplex is the name of a Russian company that produces this insulation. She has been doing this for quite a long time - for 28 years. The correct name for the material is extruded polystyrene foam. It begins its history a little more than half a century ago in the military industry. This insulation was developed precisely for the purposes of defense structures. American company. Due to its unique properties regarding thermal conductivity, as well as moisture absorption, it was used for life rafts. After this, extruded polystyrene foam was used in refrigerators. Only since the 50s has he received special recognition in construction industry. Many people confuse penoplex with regular foam, but there are certain differences between them.
Compound
The production of penoplex is a rather complex process. To complete all stages you will need the following components:
- citric acid;
- crushed perlite;
- zinc or barium stearate powder;
- polystyrene;
- sodium bicarbonate;
- additive in the form of tetrabromoparaxylene.
It all starts with polystyrene granules. To make penoplex, they are placed in a kind of autoclave, where the temperature can reach 140°. The granules form a homogeneous mass, to which powders are added. The latter contribute to the appearance of small gas bubbles in the liquid. They are the ones who give penoplex its unique properties. The resulting foam passes under pressure through the molding holes and onto the transport belt, where the processing ends and the foam is shaped into sheets. The number of gas bubbles reaches 98 percent of the entire area of the material. That is why the insulation is lightweight and has low thermal conductivity.
During the production process of penoplex, various components can be mixed into the foam, which determine exactly where certain sheets will be used. Substances that provide fire safety are called fire retardants. The air contains oxygen, which can oxidize materials, rendering them unusable, so antioxidants are added to penoplex. During installation of penoplex and during operation, it may accumulate static electricity, which can be dangerous for various devices, so special substances are added that remove such a charge. Another series of additives increases the resistance of penoplex to ultraviolet rays.
Positive and negative sides
Considering the facts that were given above about the production of penoplex, we can highlight it positive aspects. They are:
- light weight;
- ease of installation;
- moisture resistance;
- resistance to temperature changes;
- high mechanical strength;
- ease of interaction with finishing materials;
- ease of giving the required shape;
- service life up to 50 years;
- environmental safety.
You can install foam sheets yourself. They are light in weight, so they are easy to lift to heights. Even if the insulation is constantly in water, it will not absorb it. This means that penoplex remains resistant to a large freeze-thaw cycle. Due to its bubble structure, penoplex has good strength characteristics, which prevent it from being pushed through. Extruded polystyrene foam is very easy to process. You can cut it with regular stationery or construction sheet. If special shapes are required, then you can use a hot tungsten filament. If handled correctly, penoplex can last up to 50 years. At the same time, the sheets are resistant to open fire. They melt, but do not ignite. The material also has its disadvantages:
- almost zero vapor permeability;
- favored by insects and rodents;
- sensitivity to solvents;
- sensitivity to UV rays.
The poor vapor permeability of polystyrene foam suggests that it can only be used for exterior finishing. Otherwise, moisture will accumulate, which will lead to the development of fungus and mold. When insulating with penoplex, you should take care of proper finishing. The fact is that some types of ants can grow inside the insulation, which will reduce its strength and render it unusable. Rodents are able to make their homes inside foam sheets, creating unpleasant noise. Installation work Do not combine with painting or rust removal. Penoplex is destroyed under the influence of various solvents. It is not recommended to leave the insulation unfinished long time. Ultraviolet rays destroy its shell, and it begins to crumble.
Types of penoplex
It was said above that various types insulation materials are used for their own purposes. However, sheet sizes may vary depending on the application. The thickness of the individual slabs will also vary. They can be combined to achieve the best result.
Comfort
This material is universal. It can be used to insulate various parts of a building. Insulation is often used to reduce heat loss through balconies and loggias. The thickness of the sheet is usually indicated immediately in the marking. For example, if you need 20 mm penoplex, then you need to purchase Comfort 20. This thickness will be enough for additional thermal insulation of the floor or ceiling. For wall insulation, 100 mm penoplex is most often used. This is the maximum thickness for the Comfort subtype. The length and width of the sheets that are on sale are 120x60 cm.
Foundation
This type of sheet is used for foundation insulation and ground floor buildings. In some areas it will be sufficient to use 20 mm penoplex. The maximum thickness of sheets of this subspecies is also 100 mm. In this case, the maximum density reaches 33 g/m 3. The size of the individual parts also measures 120x60 cm. Thanks to this, large surface areas can be quickly covered. Distinctive feature This subspecies is the absence of a fire retardant additive, which is designed to reduce flammability. It is laid in a screed for heated floors, for insulating garden paths or beds. Such sheet insulation will ideal option for basement and cellar.
Penoplex 45
This type of sheet insulation is used for broader purposes. The maximum value of its density can reach 47 gc/m3. This indicator allows you to use even 30 mm penoplex to insulate the area on which the car will be located. The sheet size is standard for all products. Sheet material designed for laying under runways and highways with large throughput. This allows you to avoid destructive effects on asphalt during frost and thaw.
Roof
The process of roof insulation is mandatory during construction. This makes it possible to retain the heat that rises. For these purposes, this type of foam sheet was developed. It can be used with any roofing sheets. Due to its features, penoplex practically does not add weight to the roof, so rafter system will not be harmed. Roofing polystyrene foam under the Roof brand has additional fire resistance, which is very important. For high-quality insulation in areas with moderate winters, where the temperature does not drop below zero, 50 mm is enough. Sheets of standard size will have to be cut to the required size, which will depend on the distance between the rafters.
Pay attention! Penoplex 10 mm is not available, minimum thickness sheets start from 2 cm.
Wall
This type of penoplex is an analogue of “Comfort” insulation. It contains additives from substances that reduce combustion, which is important for wall material. Sheet insulation can reduce heat loss by almost 45%. It is produced in a thickness of 20 mm, but the ideal choice for wall insulation would be 100 mm. The size of one sheet and packaging is standard 120x60 cm. Due to their density, the sheets perfectly withstand mechanical stress, which is very important for walls. After all, they can most often be caught by children or craftsmen while carrying them. various materials. You can watch the installation video below.
Conclusion
As you can see, penoplex sheet insulation is ideal solution for any task. It even withstands extreme conditions. Paired with waterproofing, foam insulation sheets will prevent flooding of basements and garages under the house.
Thermal insulation materials are construction products, designed to protect enclosing structures (walls, floors, roofs, foundations) of buildings and structures from heat loss, in other words, to reduce the thermal conductivity coefficient.
Today we'll 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 of conventional polystyrene foam, however, penoplex has a number of advantages - first of all, more high 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 standard sizes, which are not difficult to install and can be easily cut to the required size.

"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, on top of the insulation you can plastering system on a mesh, or faced with any facing material facade 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. Light, hard, moisture resistant material, with excellent thermal insulation properties.
"Penoplex 45"(density 35-47 kg/m 3) - insulation road surfaces, in particular runways, to prevent them from frost heaving of the soil and destruction of the top layer of the canvas. 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.
- 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 a plaster mixture (in case of obvious unevenness of the walls) and treat them with an antifungal compound.
- Gluing Penoplex boards carried out using special adhesive compositions on a dry wall surface. The adhesive is applied directly to the insulating board.
- 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 .
- A plaster composition is applied over the insulation boards . 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. For the first time plaster layer the reinforcing polymer mesh is “recessed”. Next, a second layer of plaster is applied, after which dries, the walls are painted in the desired color.
- Instead of plaster, it is possible to finish the walls siding, wood, as well as the use of hanging systems for which the 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 foil is installed on top of the penoplex. polyethylene film 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.
- roofing material
- sheathing
- 3vapor-permeable moisture-resistant membrane
- penoplex insulation
- interior lining
- 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.
