Below is a list of frequently asked questions and answers related to PENOPLEX ® thermal insulation:

Differences between PENOPLEX ® and non-pressed expanded polystyrene (PSB)

Plates PENOPLEX ® and expanded polystyrene (PSB) differ in production technology. Pressless expanded polystyrene is created by "steaming" microgranules with water vapor in a special form and their expansion under the influence of temperature. PENOPLEX ® thermal insulation is produced by mixing polystyrene granules at elevated temperature and pressure with the introduction of a foaming agent and subsequent extrusion from an extruder. That is why PENOPLEX ® expanded polystyrene is called extruded. Also, thanks to the production technology using this technology, PENOPLEX ® obtains a closed finely 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 is also the lower thermal conductivity of PENOPLEX ® compared to non-pressed expanded polystyrene (PSB), which makes it possible to reduce the thickness of the required thermal insulation by about 30%.

Which insulation to choose: PENOPLEX ® or mineral (stone) wool?

What is better PENOPLEX ® or mineral wool? This is a question that quite often arises from private developers. Each of these materials has its own advantages. For example, PENOPLEX ® is practically indispensable in loaded structures and in a humid environment, while mineral wool shows itself better in sound insulation. In addition, some types of mineral wool have a lower price, but this plus often disappears 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:

lower thermal conductivity.

high compressive strength

absolute moisture resistance (PENOPLEX ® does not absorb water, due to which it retains its thermal insulation properties throughout the 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 protective equipment when working with it).

What is the density of PENOPLEX ® ?

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. At the same time, it is important to understand that the density of PENOPLEX ® is not a key factor in determining the scope of the material. More important is such a characteristic as compressive strength. The strength characteristics of PENOPLEX ® vary over a wider range. The minimum compressive strength at 10% deformation for PENOPLEX ® boards is 0.12 MPa, such boards are used for unloaded structures (for example, for wall insulation). Plates intended for insulation of foundations have higher compressive strengths - 0.3 MPa, since it is these structures that take on the main loads from the building. PENOLEKS ® grades intended for road construction and structures with increased loads can have a strength of 0.50 MPa and more.

A wide range of characteristics makes it possible to use PENOPLEX ® boards for insulation of almost any structure, both in cottage and low-rise buildings, and in industrial and civil construction.

What is the melting point of PENOPLEX?

The temperature range of application of PENOPLEX ® boards is in the range from -70 to +75 degrees Celsius, which allows using this material in any climatic zones.

At temperatures above 75 degrees Celsius, PENOPLEX ® can change its mechanical properties in the direction of reducing the strength of the material.

How many bricks does PENOPLEX ® replace?

If we compare materials in terms of heat-insulating properties, then a PENOPLEX ® slab 50 mm thick (λ=0.034 W/m2°C) will replace 1280 mm masonry on a heat-insulating mortar made of solid single brick (λ=0.82 W/m2°C). (According to GOST 530-2012 Ceramic brick and stone. General specifications. Table D.1 - Thermal characteristics of solid (conditional) masonry).

On average, in terms of thermal insulation properties, 1 cm of PENOPLEX ® replaces 25 cm of brickwork, but it should be remembered that for each individual type of brick (silicate, ceramic, clinker), this comparison will be different.

Not a single construction today is complete without the use of insulation. For each type of task, they try to choose the one that will last as long as possible. One of the leaders is penoplex. Penoplex 35 gk / m 3 is used even for warming tracks. But why do many people prefer to use this particular material? Understanding this will help understanding its features, as well as the sizes of sheets that are on sale.

What kind of heater

In fact, Penoplex is the name of the 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. It was for the purposes of defense structures that this insulation was developed by an American company. Due to its unique properties in terms of thermal conductivity, as well as moisture absorption, it was used for life rafts. After that, the extruded polystyrene foam was used in refrigerators. Only since the 50s has he received special recognition in the construction industry. Many people confuse foam with ordinary foam, but there are certain differences between them.

Compound

The production of penoplex is a rather complicated process. To complete all stages, you will need the following components:

lemon acid;
crushed perlite;
zinc or barium stearate powder;
polystyrene;
bicarbonate of soda;
additive in the form of tetrabromoparaxylene.

It all starts with polystyrene granules. For the manufacture of penoplex, they are placed in a kind of autoclave, where the temperature can reach 140 °. The granules form a homogeneous mass, to which porophores are added. The latter contribute to the appearance of small bubbles with gas in the liquid. It is they who give the penoplex its unique properties. The resulting foam under pressure passes through the molding holes and enters the transport belt, where the processing ends and the foam is shaped into sheets. The number of bubbles with gases reaches 98 percent of the entire area of the material. That is why the insulation is light and has low thermal conductivity.

During the production of foam plastic, various components can be mixed into the foam, which determine exactly where certain sheets will be used. Substances that provide fire safety are called flame retardants. The air contains oxygen, which is able to oxidize materials, rendering them unusable, therefore, antioxidants are added to the penoplex. During the installation of penoplex and during operation, static electricity can accumulate, 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 foam to ultraviolet rays.

Positive and negative sides

Considering the facts that were given above about the production of penoplex, its positive aspects can be distinguished. They are:

light weight;
ease of installation;
moisture resistance;
resistance to temperature extremes;
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 mount foam sheets yourself. They are light in weight, so they are easy to lift to a height. Even if the insulation is constantly in the water, it will not absorb it. This means that the foam remains resistant to a large freeze-thaw cycle. Due to its bubbly structure, penoplex has good strength characteristics, which exclude its punching. Extruded polystyrene foam is very easy to process. You can cut it with an ordinary stationery or construction sheet. If special shapes are required, then you can use a hot tungsten filament. With proper handling, penoplex is ready to last up to 50 years. With all this, the sheets are resistant to open fire. They melt but do not ignite. The material also has its drawbacks:

almost zero vapor permeability;
favored by insects and rodents;
sensitivity to solvents;
sensitivity to UV rays.

The poor vapor permeability of expanded polystyrene suggests that it can only be used for outdoor decoration. Otherwise, moisture will accumulate, which will lead to the development of fungus and mold. When insulating with penoplex, you should take care of the correct finish. The fact is that some types of ants can start inside the insulation, which will reduce its strength and render it unusable. Rodents are able to arrange their homes inside foam sheets, creating an unpleasant noise. Installation work should not be combined with painting or rust removal. Penoplex is destroyed under the influence of various solvents. It is not recommended to leave the insulation without finishing for a long time. Ultraviolet rays destroy its shell, and it begins to crumble.

Types of foam

It was said above that various types of insulation are used for their own purposes. However, sheet dimensions may vary depending on the application. The thickness of individual plates will also be different. They can be combined to achieve the best result.

Comfort

This material is universal. It can be used to insulate various parts of the building. Often, insulation is 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 foam, 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 foam is most often used. This is the maximum thickness for the Comfort subspecies. The length and width of the sheets that are on sale is 120 × 60 cm.

Foundation

This type of sheet is used to insulate the foundation and basement of the building. In some areas it will be enough to use 20 mm foam. The maximum thickness of the sheets of this subspecies is also 100 mm. In this case, the maximum density reaches 33 gc/m 3 . The size of the individual parts also has parameters of 120x60 cm. Thanks to this, large surface areas can be quickly covered. A distinctive feature of this subspecies is the absence of a flame retardant additive, which is designed to reduce flammability. It is placed in a screed for underfloor heating, for warming garden paths or beds. Such sheet insulation will be ideal for the basement and cellar.

Penoplex 45

This type of sheet insulation is used for broader purposes. The maximum value of its density can reach 47 g/m 3 . This indicator allows you to use even 30 mm foam for insulating the site on which the car will be located. The sheet size is standard for all products. Sheet material was developed for laying under runways and routes with high capacity. This avoids the destructive effects on asphalt during frosts and thaws.

Roof

The process of roof insulation is mandatory during construction. This makes it possible to keep the heat that rises up. For these purposes, this type of sheet foam was developed. It is used with any roof decking. Due to its features, penoplex practically does not add weight to the roof, so the rafter system will not suffer. The roofing polystyrene foam under the Roof brand has an additional resistance to fire, 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.

Note! Penoplex 10 mm is not available, the minimum thickness of sheets starts from 2 cm.

Wall

This type of foam is an analogue of the "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 with a thickness of 20 mm or more, but 100 mm would be an ideal choice for wall insulation. The size of one sheet and packaging is standard 120 × 60 cm. Due to their density, the sheets perfectly withstand mechanical stress, which is very important for walls. After all, they can most often be hooked by children or craftsmen while carrying various materials. You can watch the installation video below.

Conclusion

As you can see, penoplex sheet insulation is the ideal solution for any task. It withstands even extreme conditions. Paired with waterproofing, foam insulation sheets will prevent basements and garages under the house from flooding.

insulation Penoplex technical characteristics and properties - penoplex is very similar in properties to polystyrene foam, but it belongs to new developments with a completely different production technology. Due to its specificity, Penoplex is very effective in matters of wall insulation.

Foam insulation of building walls and balconies

The specifics of production and the special properties of the building material

In the production of this insulation, a special extrusion plant is used, on which polystyrene granules can be processed under high pressure and temperature. In order for the conversion process to start, a special substance is added there, which serves as a catalyst for the reaction. Often, carbon dioxide and freon in a light form are taken as such a catalyst.

The finished mixture is lush and resembles peaks of whipped cream. Through a special opening of the apparatus, the resulting substance enters the outside, where the freon is replaced by air and evaporates. Such material has rather small pores - up to 0.1 - 0.2 mm, which increases its power and heat-insulating properties. It should be noted that all cells are evenly spaced and isolated from the external environment.

Penoplex technical characteristics has the following:

Minimum moisture absorption. Tellingly, water does not have access to the internal cells of the insulation. This has a beneficial effect on 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. Even in comparison with other heat-insulating materials, it is much 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. Due to this property, the insulation of this brand can be used in attics, in the foundation, etc. without using an additional layer to protect against moisture.
Vapor permeability is low. This shows its high resistance and resistance to the penetration of gases and steam into the material. This feature is characteristic of all materials made by extrusion.

The service life of foam

Increased service life. It is able to withstand a large number of freeze and thaw cycles. According to the experiments of the NIISF institute, their minimum service life is 50 years and even more. This is subject to 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 space of the material, the latter increases its resistance to mechanical stress. Even under heavy loads, its dimensions will not change and not be compacted.
Ease of assembly and installation. Also easy to handle. Despite its strength characteristics during installation work, it is convenient to cut it into the necessary blocks using an ordinary knife. Without much effort, you can quickly and efficiently sheathe the walls with the insulation in question, without fear of snow, rain and frost.
Excellent resistance to aggressive Penoplex chemicals. This applies to chemical mixtures that 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 plates or even dissolve completely. Among the substances that can react, one can distinguish toluene, xylene, benzene, formalin, formaldehydes, ketones, ethers, gasolines and other fuels, tar from coal, oil paints. However, the insulation is resistant to acids, salts, alkalis, alcohols and spirit paints, mortars based on cement and concrete, water, freons, oils, paraffins, etc.
Environmental friendliness and safety for human health and the environment. Freons, which are used in the manufacture of these plates are not dangerous, they do not burn and do not emit toxic substances.

Penoplex can also have technical characteristics as excellent resistance to biological manifestations. Such plates do not rot and do not decompose, they do not mold, which also favorably distinguishes them for use.

Penoplex standard sheet sizes

Installation conditions for Penoplex to maintain technical characteristics

In order to ensure the unchanged shape and dimensions of Penoplex, the characteristics of which must remain unchanged, it is necessary to mount and process under the right conditions. This applies to humidity and air temperature. To do this, it is necessary to maintain the permissible air temperature at which this type of insulation can function normally during long-term operation.

Balcony foam insulation

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. However, this disadvantage applies not only to a specific type, but to all foam materials.

Product range

Depending on its characteristics, Penoplex is divided into several types depending on its application:

Insulation of the walls of houses. With it, you can insulate the basement, facades of buildings, partitions, as well as external and internal (if it is impossible to insulate external) walls.
Foundation insulation. It has a high resistance to stress. It is also used for garden paths, insulation of floors and plinths.
For the roof, as well as the roof attic with ventilation.
Comfort is an option that is perfect for warming balconies, as well as mansions in general. It is also used for warming saunas and baths.
For roofs of inversion type, as well as thermal insulation of highways, railways, etc. In this case, Expanded polystyrene is used, the technical characteristics of which are many times higher than in other types of heaters. This is especially true for resistance to various loads.

Note information : , .

The performance characteristics of foam insulation for walls bring it to a leading position in the installation of thermal insulation inside and outside buildings.

The production technology of extruded polystyrene foam makes it an almost universal board material that gives a stable result with the correct calculation of the thickness of the insulating layer and compliance with the installation rules.

What is penoplex

The heat insulator will reduce the cost of heating the house in the future

Heat loss through the walls of a building can range from ¼ to 1/3 of the total. An increase in thermal resistance due to the inclusion of special coatings in the design of the outer walls makes it possible to reduce its thickness and reduce the consumption of other building materials.

Wall panels suitable for heat and sound insulation

Penoplex is produced in the form of 5 main varieties that differ in the purpose of the types of work.

Fundamental. Mounted on the basement (underground) part of the building, used as a fixed formwork. Protect the base of the building from freezing.
Wall. Needed for outdoor work on thermal and sound insulation.
"Roof". It is installed on attic floors and roof slopes, attic rooms. Traps the heat and sound of rain.
"Comfort". It is intended for internal works (walls, floors, ceilings, balconies).
Road. The most dense grade of this material is labeled "Penoplex-45".

Installation work on the outer part of the wall does not differ in composition from the implementation of internal insulation.

When performing thermal insulation work, they are used. These materials can significantly reduce heat dissipation into the surrounding space. Penoplex is especially popular, the technical characteristics of which make it possible to use it in various regions. By choosing plates of suitable thickness, you can ensure a sufficient level of thermal insulation of walls, floors, ceilings. Let's talk about this heater in more detail.

Penoplex - universal heat-insulating material

Penoplex - extruded polystyrene foam, which got its name from the trademark of the same name. It belongs to the category of the most popular thermal insulation materials due to its unique technical characteristics and reasonable cost. It is actively used for warming various surfaces in the construction and reconstruction of residential buildings and public buildings.

During the production process, polystyrene granules are foamed under conditions of high pressure and temperature. Carbon dioxide and light freon act as a catalyst for the process. The finished mass, similar to cream whipped with a mixer, is blown out through special nozzles of the extrusion unit. Here freon evaporates, and the resulting voids are filled with air.

This production technology makes it possible to obtain a finely porous material, inside which adjacent cells with air are isolated from each other. The diameter of the air pockets does not exceed 0.1-0.2 mm. Due to the uniform distribution throughout the volume of the material, the manufacturer provides the required level of properties. The material has high strength and shows excellent thermal insulation characteristics. With the selection of material of sufficient thickness, the desired effect can be achieved.

Note! Penoplex 50 mm is used in the insulation of buildings, roads, runways.

The manufacturer offers various types of thermal insulation material:

Foundation able to withstand significant loads during operation. The minimum thickness of the plates is 50 mm. If necessary, you can order a thicker heat insulator if the building will be operated in the northern regions;
Roof, which has a special shape that facilitates the process of laying plates. With the help of heat-insulating material of this type, it can provide high-quality protection of the roof from external cold. In this case, it becomes possible to use the attic as a living space;
Comfort. Penoplex thickness of 30 mm, as a rule, is sufficient for high-quality thermal insulation of the walls of a residential building or loggia;
Wall. Suitable option for wall insulation inside and outside the job. The thickness of the material can be 20-50 mm. If the work will be done from the inside, it is better to choose a thinner material. For the facade, it is worth ordering thicker plates.

Attention! The thickness of foam 10 mm is not enough for high-quality insulation of the walls of a building operated in winter. Thicker plates should be chosen, for example, 70 mm.

The main technical characteristics of penoplex for the foundation

In terms of technical characteristics, Penoplex GEO corresponds to the old type Penoplex 35, the production of which was carried out without flame retardant. It is used for thermal insulation of surfaces, the fire resistance of which is not subject to increased requirements. The material belongs to group G4.

The main area of application of the heat insulator is the insulation of loaded structures, followed by the application of a protective layer. The material is in demand when constructing a cement-sand screed, thermal insulation of the foundation, floor, building basement or garden paths. The slabs become a reliable protection for, providing groundwater drainage and reducing their impact on underground structures of buildings.

Note! A bioresistant durable insulation is in demand when building a shallow foundation on heaving soils.

The minimum thickness of foam plastic Foundation is 50 mm. If necessary, you can also purchase plates with a thickness of 80 mm. Plates are able to withstand significant loads throughout their entire service life. Their strength with a linear deformation of 10% is 0.25 MPa. Water absorption by volume for 4 weeks does not exceed 0.5%. The insulation is able to last more than half a century, including when operating in the harsh climate of the northern regions.

The main technical characteristics of comfort foam

This type is universal. Technical characteristics of Penoplex Comfort 50 mm allow thermal insulation of many surfaces. With its help, simultaneous insulation of the roof, basement, floor and foundation of the building is carried out. The low level of water absorption, not exceeding 0.5% for 4 weeks, makes it possible to use Comfort for insulation, a pool or. Thermal insulation of other objects, the operation of which is carried out in conditions of high humidity, is possible.

Tight docking of elements among themselves contributes to the stability of enclosing structures. Not subject to biodegradation. You can not be afraid that insects will appear inside the heat-insulating material, which will destroy the structure of the plates from the inside. Able to serve more than 50 years, retaining its technical characteristics. It can be operated in various regions, including the northern ones.

The material is quite dense, and therefore does not sag when attached to a vertical structure. It is necessary to correctly install and securely protect all plates. Density of Penoplex Comfort is regulated by TU 5767-006-54349294-2014. When cut, it does not crack or crumble. The compressive strength depends on the thickness of the plates: if less than 60 mm - 0.12 MPa, more than 70 mm - 0.18 MPa.

Attention! Finishing must be carried out on the insulated surface.

Applying the finishing layer allows you to:

Give the penoplex an aesthetically attractive appearance. The material itself does not allow the formation of a beautiful surface that could be exploited without additional processing;
Prevent discolouration of plates;
Avoid material degradation.

Main technical characteristics of penoplex Roofing

Plates Penoplex Roofing are in demand in the construction industry. The material of characteristic orange color is produced with a density of 35 kg/m3. Allows you to form a rigid and moisture-resistant heat-insulating layer with low weight. It can be used for various types of roofing, thermal insulation of building facades, floors and walls of buildings being erected and reconstructed, basements, and engineering communications.

The material is classified as moderately flammable. During combustion, it emits a large amount of smoke. This feature should be taken into account when choosing a heater for a dwelling.

A special connection of the tenon-groove elements makes it possible to form a homogeneous layer that does not have cold bridges. Due to the refusal to overlap adjacent elements during the installation process, it is possible to optimize the thickness of the heat-insulating layer being arranged and more rationally manage the free space.

Water absorption by the volume of the plates does not exceed 0.5%, and therefore the heat-insulating layer practically does not absorb moisture. High strength makes it possible to withstand a significant load that the heat-insulating material may be subjected to during the installation of plates and the subsequent operation of the insulated object.

If the facade of the building is to be insulated, instead of foam roofing, you can use a special type of heat insulator. Its characteristics are initially adapted for this type of work. The price of Penoplex insulation for walls outside the house is acceptable for many. It depends on the thickness of the plate. For you can purchase material with a thickness of 20 mm, for a residential building - 50 mm.

Extruded polystyrene foam: technical characteristics and price of quality boards

This type of thermal insulation material became available to users more than half a century ago. Extruded polystyrene foam, sometimes referred to as extruded polystyrene foam, immediately became a universal insulator that is in demand for a variety of jobs. Manufacturers offer sheets of standard size, which can be transparent and colored. Sheet plastic, due to its special structure and unique production technology, demonstrates high performance during operation.

Attention! Before buying, you should find out the required characteristics of insulation. Penoplex must meet the requirements.

The technical characteristics of 50 mm foam plastic may vary slightly depending on the type of material. However, in most cases they vary within a fairly narrow range.

The technical characteristics of penoplex 35 include:

Low water absorption capacity. The main advantage of this heater. The heat insulator absorbs water molecules only on sections, since air cells are open in these zones;
Low thermal conductivity. On average, this indicator is 0.03 W/m·S;
Versatility. The manufacturer offers material of various thicknesses, making it possible to insulate many surfaces. It is used for thermal insulation of walls, foundations, loggias and balconies;

Low vapor permeability;
Long period of operation. Penoplex is able to withstand repeated freezing / thawing without loss of basic performance. On average, such material can last about 50 years;
High strength. During operation, the insulation withstands a significant load and pressure due to the presence of tiny air bubbles in the material that prevent compression of the material;

Ease of installation. The material can be easily cut with a sharp knife, giving the elements the desired shape. The cut site does not crumble. Installation work can be carried out all year round, as the heat insulator is not afraid of exposure to UV rays and high humidity. Plates can be fixed at any time of the year;

Ecological safety. In the production process of insulation, freon is used, which does not have a negative impact on the atmosphere. During operation, the insulation does not emit substances that can have a negative effect on the human body;
Fire safety. The material is resistant to burning;
Minimum chemical activity and biological inertness. When performing construction work, a large number of substances with increased surface activity are used. Only a few are capable of interacting with penoplex. The heat insulator does not rot or decompose.

Penoplex is not the only extruded polystyrene foam that can be purchased for home insulation. Similar technologies are used by other manufacturers, offering high-quality insulation.

The technical characteristics of Technoplex are somewhat different from those of Penoplex. This contributes to the change in the composition of the raw materials used. A certain amount of graphite is added to the composition of the mass subjected to extrusion. The result is a highly effective insulating material resistant to water.

Technoplex absorbs noise well and has a long service life. At the same time, it is somewhat inferior in strength. Works well at fairly low temperatures, typical for the Far North and has a lower level of water absorption. Only 0.2%. However, when buying this type of thermal insulation material, you will have to pay more. Considering that a large amount of material is usually required for wall insulation, this factor can be decisive when choosing.

Penoplex sheet sizes: how to choose the right one?

A special technology for the production of extruded polystyrene makes it possible to form a material with a unique structure that ensures high strength of the boards and guarantees unique thermal conductivity. As a rule, a material of small thickness is used for thermal insulation of various surfaces. When choosing a suitable option, you should focus on the manufacturer's recommendations.

If it is necessary to carry out the insulation of an object, the operation of which will be carried out in a temperate climate, you can use plates with a thickness of 35-50 mm. Their technical characteristics will provide the necessary level of thermal insulation of walls or roofs.

For regions located in cold climatic zones, it is worth purchasing a 70 mm thick insulation. Even if the frost is more than -30°C, a comfortable temperature will be maintained inside the building.

For foam boards, the dimensions are standardized. The manufacturer offers plates with a length of 1.2 m and a width of 0.6 m of various thicknesses. The last dimension can be in the range of 20-150 mm. The choice of a suitable thickness should be made taking into account the operating conditions of the surface to be insulated.

Before buying a thermal insulation material, you should calculate the required amount. To do this, you need to know the area of \u200b\u200bthe insulated surface. You should definitely find out by choosing 50 mm foam, how many m² are in the package. This will depend on the number of packages that you need to purchase. Sheets are also sold individually, and therefore the missing quantity can be purchased additionally.

For those who buy penoplex, how many pieces per package matters. This indicator depends on the thickness and type of plates. For a material with a thickness of 50 mm, the ratio is as follows:

Type of insulation	Image	The number of plates in the package, pieces
Comfort		7
Wall		10
Foundation		8

Penoplex price 50 mm: the main factors affecting the cost

Penoplex sizes and prices are directly dependent. The thicker the plate, the more you have to pay for it when buying a heater. In addition, the type of material has a significant effect. In the production process, certain components are introduced into the composition of the raw materials used. This inevitably affects the cost of the produced material.

Advice! To find out how much penoplex costs, just tell the seller the required thickness of the insulation and its type.

If you are interested in the price for a foam sheet of a certain type and thickness, you can focus on the following data:
