Extruded polystyrene foam penoplex characteristics. Penoplex - technical characteristics, brands and distinctive features of the material. Types and technical characteristics of thermal insulation boards
Using various thermal insulation materials, I would like to know all the pros and cons of insulation elements, as well as their technical characteristics and properties. Today I will talk about a popular material that is most often used for do-it-yourself insulation. Due to its low cost and good heat retention performance, penoplex remains popular not only for home craftsmen, but also for many professionals.
Penoplex
Acquaintance with penoplex
Penoplex for room insulation
Before moving on to discussing the main characteristics that penoplex has, it is worth understanding what it is. Penoplex boards are foamed polystyrene, which, in contrast to polystyrene, has a higher density and strength. Thanks to this, penoplex is used in harsh climates, and due to its low water permeability, it can be used in any weather.
Penoplex properties allow it to be used when self-insulation, and the advantages of this material are:
- Low water permeability
- Very light weight, despite which the density values remain very high
- High compressive elasticity
- Good thermal insulation
- Durability and environmental safety
Important! The special popularity of penoplex is explainable precisely due to the low indicators of water permeability. Thanks to this, it is used not only for insulating houses, but also for water supply systems and road surfaces.
Let's take a look at the standard sizes of expanded polystyrene plates, which differ in their density, using the example of a table:
Important! The operating temperature of the penoplex ranges from -50 degrees to +75 degrees.
The technical characteristics of the plates are quite good:
- Density - 25-48kg / m3
- Strength - 0.2-0.6 MPa
- Water vapor permeability - 0.007-0.008
Interaction of material with various substances
We insulate the balcony with penoplex
Since not only the density indicators of the penoplex or its technical characteristics are important for us, I decided to write with which substances this material should not be used. Having in themselves various components, these substances destroy the integrity of the material, which speaks not only of a decrease in properties, but also of the complete destruction of thermal insulation plates. So, you shouldn't use it with Penoplex:
- Oil paint
- Gasoline or kerosene
- Benzene, xylene, toluene
- Acetone
Since the list of these substances is not long, it is very easy to remember it and in the future to avoid mistakes that can affect the quality of the work done. By the way, the list of materials with which it interacts well is much larger:
- Water based paint
- Saline solution
- Alkaline compounds
- Lime
- Butane and propane
- Cement-concrete mixtures
- Ammonia
- Freon
Since penoplex does not react at all with these materials, it becomes possible to use it in tandem with these substances.
Varieties of insulation boards
We insulate the floor on the balcony
Since there are plenty of varieties of penoplex on the construction market, manufacturers release it with specific names that allow you to speed up the selection process. Let's take a look at these types:
- Penoplex "roof" - the density of the slabs for roof insulation is 28-33kg / m3. Differs in lightness and water resistance
- "Wall" - can be used for both indoor and outdoor work. The density of the material is 25-33kg / m3
- "Foundation" - high density and waterproofness allows the use of the material during the construction of a foundation or basement. Density - 29-33kg / m3
- "Comfort" - slabs are used for balconies and apartments, as well as non-insulated loggias. Density - 25-35kg / m3
- Penoplex "45" - this material differs among others in the highest density, which is 35-47kg / m2. It is because of this that it is used during the construction of road surfaces and runways.
For an ordinary consumer, I made a table of the approximate cost of penoplex. Thanks to her, you can make approximate calculations of the amount required to purchase material of different thicknesses:
| Name | Thickness | Area / volume in the package. m2 / m3 | Sheets in packaging (number) |
Cost of 1 package | Price for 1 sheet |
| PENOPLEX | 20 | 14,4/0,288 | 20 | 1 200 - 1 400 | 60-70 |
| 30 | 10,08/0,30 | 14 | 1 260 - 1 540 | 90-110 | |
| 40 | 7,2/0,288 | 10 | 1 200 - 1 400 | 120-140 | |
| 50 | 5,76/0,288 | 8 | 1 200 - 1 520 | 150-190 | |

| 100 | 2,88/0,288 | 4 | 1 200 – 1 240 | 300-310 |
DIY installation
Installation of penoplex on the ceiling
Fastening of thermal insulation boards is carried out using a simple and affordable technology for everyone. Since I have already carried out insulation with my own hands more than once, I decided to describe all the stages by which the installation of the penoplex takes place:
- Wall Preparation - At this stage, all dirt and grease stains, as well as dust and old finishes, should be removed from the surfaces. If necessary, you need to apply plaster mixes, with the help of which all cracks and obvious irregularities are repaired. In addition, the walls are treated with antifungal agents.
- Before fixing the penoplex, you should make a choice among the fastening materials: you can use an adhesive solution that will be applied to the surface of the plate. It should be remembered that the surface of the walls must be completely dry. In addition, it can be applied using dowels. For 1 sq. meter, you should take 4 dowels, while at the corners of the house you should use more fastening materials
- When the thermal insulation is fixed, you should proceed to further steps for finishing the facades. Here you can use wet technology and apply plastering compounds - for better strength, you need to create additional roughness and apply a reinforcing mesh
- For those who do not like the use of plaster for wall cladding, the option using siding, wood or another type of hinged system is suitable, for which the installation of the lathing is required
There are times when it is not possible to produce insulation outside the house. In this case. Penoplex plates are attached to the inner walls, after which they are covered with foil-clad plastic wrap and sheathed with gypsum board sheets. After that, you can make the next interior decoration rooms.
Analogue of heat-insulating material
We insulate the floor in the room using penoplex
Since the construction market is constantly replenished with new materials that can be used in insulation processes, I decided to touch on the topic of an analogue of penoplex with improved characteristics. This is the material technoplex, which is made from expanded polystyrene, but due to the addition of nano-particles of graphite, it has even lower thermal conductivity and improved density and strength.
by the way temperature regime at the technoplex it is also expanded, and if the penoplex can be used from -50 degrees, then the technoplex is from -75 to +75 degrees. However, if we talk about our climate, then such an indicator will not play any role and therefore I, like many, do not understand the need to use this variety. If we talk about the cost of the material, then technoplex is not much more expensive than penoplex. The difference is about 10%, although in large areas, these percentages can result in a pretty penny.
The most interesting thing is that foam plastic has long been used not only good stuff thermal insulation. With its help, foam decor is created, which is able to turn the appearance of facades into a real work of art. Due to the low cost, the transformation appearance Everyone can afford a house, but the main thing is that this architectural element fits into the overall style of the building.
High-quality insulation becomes possible if the insulation is correctly selected. But this is not easy to do, because the market offers quite a lot of different solutions. Penoplex is one of the effective materials. Before buying, you should find out how much material you need. For correct calculations, you need to be aware of the size of the penoplex. Competent work contributes to the creation of a warm microclimate in the home.
The produced types of penoplex make it possible to use it to carry out work on the insulation of almost any structures erected by man.
general information
Penoplex is a material consisting of expanded polystyrene, which is produced by extrusion. It can be used to solve a wide range of tasks in the field of thermal insulation of objects. It is actively used not only during work in residential premises. It often happens when it is used to insulate industrial buildings.
Thermal insulation of attic rooms and building facades is carried out more and more often using of this product This product was developed in the USA. A special technique, which involved the use of the extrusion method, made it possible to obtain a new solution with a uniform structure. The insulation contains many small finished cells. Their size does not exceed 0.2 mm.
Heat insulator production technology involves mixing polystyrene granules under high temperature and pressure conditions. During this operation, a blowing agent is added. As such, oxygen dioxide is used or a mixture consisting of two light types of freons is used. At the end of production, the remaining blowing agent in the cells is easily filled with ambient air.
In this video, we will show you which insulation should be used for your home:
Main advantages
Penoplex is a popular material, as it allows you to effectively solve the problem of insulating structures. It can be used to increase the thermal insulation of walls, foundations and roofs. In this solution, consumers are attracted by the following advantages:
Penoplex is used for thermal insulation of foundations, roofs, walls, floors and other structures for various purposes. - Lack of water absorption. The presence of this quality is due to the fact that the material has a special structure. Therefore, exposure to liquids does not lead to their penetration inside. Even its surface is impervious to moisture. Therefore, this factor is not negative for him and does not lead to the destruction of the insulator.
- Low thermal conductivity of foam. Experts classify it as an effective material for insulation. This is largely due to the high thermal conductivity. For him, it is 0.03 W / (m · K). In this regard, the product is noticeably superior to many solutions.
- Low vapor permeability. The insulation is highly resistant to water vapor. The slab, which is 20 mm thick, resists steam penetration well.
- Durability. The service life of the heat insulator is at least 50 years. An important point is that even with multiple cycles of defrosting and freezing, the insulator does not lose its technical and physical properties... Therefore, it is applicable in any environment.
- Excellent compressive strength. It is due to the presence of a uniform structure in the foam, which provides high compressive strength. It remains unchanged during the entire period of its operation.
When using this solution, it is easy to perform installation works When carrying out activities for warming, specialists do not have any difficulties. Material slabs are easy to install. They can be easily adjusted to the required dimensions. There are no difficulties with the processing of penoplex. You can use a regular knife for this. Works are allowed to be carried out in any weather conditions. During the events, the use of any protective equipment is not required.
Material marking
There are several varieties of this insulator. Naturally, depending on the marking of the penoplex material, the insulation characteristics will differ, as well as its purpose.
Penoplex material has a high coefficient of compressive elasticity Penoplex-Wall... For this brand of product, the density varies between 25-32 kg / m³. Plates are used for insulation of external and interior walls buildings. Also, the material can be used to increase the thermal insulation of partitions and the basement of buildings. Often, the solution is used to improve sound insulation in rooms. After installation, the slabs are covered with a layer of lining, siding or decorative tiles.
Penoplex-Foundation... The product description indicates that its density is 29-33 kg / m³. Its main purpose is clear from the name. It is used for thermal insulation of the foundations of buildings, as well as surfaces in basements. The main characteristic of this type of insulation is moisture resistance. Therefore, it is suitable for thermal insulation of shallow septic tanks. Treatment systems with such an arrangement have a high risk of freezing.
Penoplex-Roofing... The main use of this solution is related to the insulation of truss systems and flat roofs. It is also good choice and for isolation attic floors... The density of the material is 28-33 kg / m³. This is what explains its incredible lightness. Once laid, it does not create much stress on the rafter system, therefore, it is not necessary to carry out work to strengthen the roof structure.
Penoplex-Comfort... This brand of a popular product is used for insulating surfaces in apartments, balconies and loggias. It is also actively used for work in private houses and for thermal insulation of baths and saunas. Although the density of the material is insignificant, it is quite suitable for thermal insulation of surfaces in residential buildings. The operating conditions there do not imply a serious load on the penoplex. Therefore, its damage or destruction is excluded.
Penoplex-45. It is characterized by density indicators ranging from 35 to 47 kg / m³. Plates can be used not only on balconies, but also for floor insulation in garages and parking lots.
Sheet sizes
Plates with a thickness of 2 to 10 cm are intended for insulation of internal walls and surfaces of a building Having chosen penoplex, in order to correctly calculate the amount of material, you need to find out the dimensions of the sheet. He has the following: length - 1200 mm; width - 600 mm. The thickness of the foam is its main difference from other solutions. This parameter varies for insulation in the range from 20 to 100 mm.
For example, Penoplex-Comfort in one package can contain at least four plates with a thickness of 20 mm, and their maximum number is 18 pieces of 100 mm each. If we talk about another brand - Penoplex-Foundation, then its thickness indicators are 50 and 80 mm. Packages contain five or eight plates.
Often, a 50 mm insulation is used to perform work.
Features of wall insulation
Internal work can be carried out with material no more than 2-3 cm thick, taking into account that the space of your home will be somewhat reduced, just by the amount of insulation thickness This material can be used for a wide range of insulation works. It is often used to improve wall insulation. If you need to make the facade of the building warm, then when holding events, you should clearly adhere to a certain sequence stages:
- The procedure for isolating external walls with foam plastic begins with preparatory measures. The surface of the facade must be cleaned of dirt and dust. Remnants of old finishing materials are also removed and paints and varnishes... After that, you should carry out the procedure for leveling the walls. For this, modern plaster mixes are used. They are resorted to if the walls have serious irregularities. After completing this operation, their surface must be treated with an antifungal composition.
- Next, the plates are fixed to the wall by gluing. For this, special formulations are used. Work can only be carried out if the facade surface is completely dry. The adhesive must be applied to the heat insulator.
- The next action is to fix the penoplex mechanically. Dowels are used as fasteners. For every square meter plates norm - 4 pieces. When insulating the perimeter of windows and doorways, as well as work on the corners of the building, it is necessary to increase the number of dowels to 8 pieces.
- Upon completion of the installation of the boards, it is necessary to apply the plaster composition. In order for the insulation to adhere well to the wall, it is necessary to create a roughness on the surface of the material with the help of a brush. It is necessary to sink a reinforcing mesh made of polymers into the first layer. Then the second layer is laid. After it dries, you can proceed to the next step - painting the walls.
Material manufacturers release it under several brands, the name of which speaks for itself and greatly facilitates our choice. If there is no desire to cover the walls with plaster, you can carry out work using modern finishing materials or arrange on the facade of the building suspension system... In the latter case, you must first create a frame.
Not all buildings have the option for external insulation. In such cases, the material is laid from the inside. The technology for performing the work is similar. But on the surface of the penoplex it is necessary to install a foil film. It will act as a vapor barrier. Already on top of it, the sheets of drywall are fixed, on which the wallpaper is glued. To fix the crate, on which the drywall sheets will be hung, it is necessary to use dowels. They are mounted in the wall through insulation. Thermal insulation of balconies and loggias takes place in a similar way.
If you plan to use drywall, then it is best to purchase sheets of a moisture-resistant type. When carrying out work on the loggia, you should not be limited only to walls, you need to additionally lay the plates on the floor. In this case, the effect of the work will be maximum.
Roof insulation
Work begins with laying insulation on the rafter system Thermal insulation measures for this structural element are performed either during construction or during the reconstruction of an old object. Often, insulation is carried out to turn cold attic to the living quarters. Before starting work, you need to prepare materials:
- metal tile or other roofing solution;
- lathing;
- vapor-permeable moisture-resistant membrane;
- insulation;
- inner lining;
- rafter structure.
Work begins with the installation of insulation on the rafter system. The material is staggered. After that, you need to lay a vapor-permeable membrane on it. Further, with the help of longitudinal slats with a thickness of at least 40 cm, a heat insulator is fixed. In order to ensure ventilation between it and the roof, it is necessary to maintain a step of 300 mm.
After that, you can proceed to securing the cross rails. Then, after placement, the roofing material is fixed on them. It is permissible to use metal tiles or any other.
Roll-to-roll solutions for continuous flooring are a good alternative. Penoplex differs from another popular insulation product - penoflex by its high cost. However, this disadvantage is paid off by its superior performance. It is ideal for plastering systems.
Penoplex is one of the best materials to create effective thermal insulation. If the cold is constantly felt in the home, then using it allows you to solve this problem. There are serious costs involved in carrying out the work. But they are offset by savings in heating the rooms. Competent conduct of the procedure minimizes heat loss and provides comfort during living.
Penoplex, like ordinary expanded polystyrene foam, is obtained from the same substance - general polystyrene granules. But in the manufacture of penoplex, a different production method is used. The polystyrene granules are heated and the result is a homogeneous liquid melt, into which a gas (blowing agent) is introduced under high pressure. The melt, as it were, boils, which contributes to the uniform distribution of the gas throughout the volume of the liquid substance. Then the process of extrusion (extrusion or extrusion) of the material takes place through calibrated holes - dies. This process is achieved specifications penoplex, which are inaccessible to other types of insulation.
In the process of cooling the plates, the gas in the cells of the extruded polystyrene foam is gradually replaced by the surrounding air and, as a result, the penoplex in its finished form does not contain gases of foaming agents. By the way, PENOPLEX ® uses the most common CO2 as a blowing agent, i.e. carbon dioxide that surrounds us everywhere. Therefore, when giving unique technical characteristics to penoplex, absolutely no damage to the environment is caused.
Another feature of outstanding technical characteristics is the fact that PENOPLEX ® itself produces polystyrene raw materials for its own needs under the STYROVIT® trademark. This suggests that the production of penoplex does not depend on third-party suppliers, and the manufacturer always achieves unchanged technical characteristics of the penoplex.
The main properties of Penoplex
Excellent thermal performance
- Minimum thermal conductivity
- Almost zero water absorption
- Absolute vapor tightness
- Excellent compressive strength characteristics
- Immunity to most natural aggressive environments
- Environmental Safety
- Convenience and ease of use
- Unique durability without loss of essential qualities
Produced types of Penoplex
Penoplex insulation produces several types, which differ somewhat in technical characteristics from each other.
"PENOPLEX ROOF"(old designation Penoplex 35) - extruded polystyrene foam intended for insulation flat roofs large construction sites, such as shopping and entertainment centers, hypermarkets, indoor sports arenas and similar structures. The main difference in the technical characteristics of this foam is that the material is produced with a density of 28.0 to 32.0 kg / m3, a compressive strength of at least 0.25 MPa (this is approximately 25.0 tons per square meter!) And a reduced the degree of flammability G3 (normally combustible materials) due to the introduction of fire retardants into the material (i.e. materials that reduce the degree of flammability of the material).
"PENOPLEX FOUNDATION"(the old designation Penoplex 35 Standard) is a penoplex, the technical characteristics of which provide for its use in loaded structures, under a protective layer, i.e. in all structures of foundations, insulated industrial floors for pouring cement-sand or concrete screeds, insulation of stylobates >>>, insulation of footpaths on heaving soils, as well as in loaded structures that are not critical to the flammability of the material. Features of the technical characteristics of foam F is increased compressive strength at 10% deformation of 0.27 MPa (approximately 27.0 tons per square meter), density 28.0-32.0 kg / m3 and the degree of flammability G4 (highly combustible). Due to its high flammability, the insulation must be constructively protected.
"PENOPLEX WALL"(old designation Penoplex 31) with a low density and, accordingly, slightly reduced technical characteristics of penoplex, it is used to insulate the walls of buildings and structures under different kinds coatings - plaster facades, frame walls, ventilated facades, etc. systems. The features of this type of product are G3 flammability and lower material density from 25.0 to 32.0 kg / m3, respectively, and lower compressive strength of 0.2 MPa, which is more than sufficient in its fields of application.
PENOPLEX COMFORT(the old name is Penoplex 31 Standard), a specially developed type of extruded polystyrene foam used for private developers. The technical characteristics of penoplex comfort cover almost all the needs of households for thermal protection of apartments, summer cottages, farm buildings, saunas, baths and cottages. The widespread use of Penoplex Comfort determines it low price and excellent consumer qualities of the material.
"PENOPLEKS 45"- a special type of material that is used in highly loaded structures. Penoplex 45 technical characteristics allow it to be used in automotive and railways, runways of airfields, insulated floors for placing massive equipment and high-loaded machines, parking lots for heavy vehicles and other similar projects. The material is characterized by increased density from 38.0 to 45.0 kg / m3 and fantastic compressive strength at 10% deformation - 0.5 MPa (or about 50.0 !!! tons per square meter). Fire retardants are not introduced into this type of material, so it needs constructive protection.

Durability of extruded polystyrene foam Penoplex
In the early 2000s, in Austria, they decided to test extruded polystyrene foam, which has been used for several decades in the structures of inverted roofs - the so-called roofs on the contrary, where the waterproofing carpet is located under a layer of insulation. You can read about the device of such roofs and their advantages on our website.
The objects of the Space Communication Ground Station in Aflenz, Austria, which were built in 1980, and the Shipping Center, Vienna, Austria, built in 1981, were selected. Specialists of the Austrian Research Institute of Chemistry and Technology opened the roofing pies at the above facilities, inspected and examined the technical characteristics of the XPS for changes
Also in 2004, in Germany, by the European Institute thermal insulation materials A similar work was done to study the technical characteristics of XPS samples taken from the inversion roof of an office building in Hamburg (Germany), which was installed more than thirty years ago - in 1972.
Studies have shown that the technical characteristics of extruded polystyrene foam have not changed over the years, and continue to perform their functions of thermal protection. roof structures still
In Russia, similar studies of the technical characteristics of penoplex were carried out by specialists from the Research Institute of Construction Physics (NIISF), who came to the conclusion that with repeated freezing-thawing, penoplex does not change its thermal characteristics, and its service life in enclosing structures, taking into account the safety factor, is at least 50 years.
Additional information on the technical characteristics of Penoplex
Penoplex thermal insulation is made in the form of plates 1200 mm long, 600 mm wide, and 20 to 200 mm thick. For extruded polystyrene foam boards, a quarter around the perimeter was selected (except for foam boards with a thickness of 20 mm), which affects the effectiveness of insulation, while creating continuous thermal insulation that does not allow "cold bridges". Penoplex 45 is distinguished by the production of slabs 2400 mm long with a quarter cut on all sides, and for the insulation of railways (railway) - 4000 mm and 4500 mm long with a straight edge on the short side and an oblique quarter on the long side.
The penoplex plate is marked with the type of material, batch number and date of manufacture, as well as overall dimensions. Penoplex slabs are packed in packs of several slabs, wrapped in orange shrink-wrap plastic wrap to protect them from ultraviolet radiation. The packaging contains the designation of the type of penoplex, and a label with the main parameters is pasted. Short-term storage of the penoplex in direct sunlight without changing the technical characteristics is allowed, but long-term storage leads to a change in the surface layer, therefore, during the production process, it is necessary to take measures to quickly shelter the penoplex from direct exposure to UV rays.
All Penoplex products are certified by the Gosstandart system Russian Federation and has everything Required documents, certificates and permits.
The number of plates in a package, its volume are indicated in the table.
Chemical resistance of Penoplex
Penoplex, and indeed any extruded polystyrene foam, has high chemical resistance to a wide range of materials used in construction. But there are chemicals that lead to softening, shrinkage and partial dissolution of the boards.
Low chemical resistance to the following substances:
Aromatic hydrocarbons (benzene, toluene, xylene)
- Aldehydes (formaldehyde, formalin)
- Ketones (acetone, methyl ethyl ketone)
- Ethers and esters (diethyl ether, solvents based on ethyl acetate, methyl acetate)
- Gasoline, kerosene, diesel fuel
- Coal tar
- Polyester resins (epoxy hardeners)
- Oil paints
High chemical resistance to the following substances:
Acids (organic and inorganic)
- Salt solutions
- Corrosive alkalis
- Bleaching powder
- Alcohol and alcohol dyes
- Water and water based paints
- Ammonia, carbon dioxide, oxygen, acetylene, propane, butane
- Fluorinated hydrocarbons (freons)
- Cements (mortars and concretes)
- Animal and vegetable oil, paraffin
If after reading this article you still have questions, please contact our company and we will give you a full explanation of the technical characteristics of the wonderful Penoplex insulation.
Thermal insulation materials are construction 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 boards are extruded expanded polystyrene produced in the form of boards. The structure of penoplex is similar to the structure of ordinary foam, however, penoplex has a number of advantages - primarily, higher density and strength.
Penoplex technical characteristics:
- low thermal conductivity (coefficient of thermal conductivity 0.03 W / m · ºK);
- high strength (both in compression 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, not subject to decay);
- wide operating temperature range (-50 ... + 75 ° С).
Extruded polystyrene foam is available in several types (depending on density and field of application) in the form of plates of standard sizes, which are not difficult to install, easily cut to the desired size.
The table shows the approximate cost PENOPLEXA COMFORT, suitable for insulation of foundations, walls, floors in cottages and apartments. The price depends on the amount of purchased material - the larger the volume, the lower the price, and of course from the region of residence.

"Penoplex WALL"(density 25-32 kg / m 3) - designed for insulation of external and internal walls, partitions, plinths for effective heat conservation and savings on heating costs in buildings. These slabs are also used in the construction of buildings when erecting walls with "well masonry".
In the case of insulation of the outer walls with penoplex, a plastering system can be made on top of the insulation along the grid, or revetted with any facing facade material(siding, tiles, lining).
"Penoplex FOUNDATION"(density 29-33 kg / m 3) - used in construction basements, construction of foundations, insulation of septic tanks. Plates penoplex FUNDAMENT have increased strength and almost zero water absorption coefficient.
"Penoplex ROOF"(density 28-33 kg / m 3) — specially produced plates for thermal insulation of flat and pitched roofs... Lightweight, tough, moisture resistant material with excellent thermal insulation properties.
"Penoplex 45"(density 35-47 kg / m 3) - insulation of road surfaces, in particular of runways, to prevent them from frost heaving of the soil and destruction of the upper layer of the canvas. It is also widely used for insulating roofs in use, on which pedestrian zones and various sites are located, including parking lots.
"Penoplex COMFORT"(density 25-35 kg / m 3) - a brand of thermal insulation boards used in housing construction (private residential buildings, insulation of walls of apartments, as well as loggias and balconies).
Penoplex installation
Penoplex insulation of outer walls 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 and varnish coatings. It is recommended to align the walls with plaster mix(in case of obvious irregularities in the walls) and treat with an antifungal compound.
- Bonding boards "Penoplex" carried out with the help of special adhesives on a dry wall surface. The adhesive is applied directly to the thermal insulation board.
- Mechanical fastening made with dowels, at the rate of 4 pcs. US 2 , after gluing the boards with glue. Along the perimeter of windows, doorways and at the corners of the building, the number of dowels increases - 6-8 pcs. US 2 .
- A plaster composition is applied on top of the insulation boards ... For better adhesion of the plaster to the insulation, it is recommended to create a roughness on the surface of the slabs using a carriage. The reinforcing polymer mesh is "embedded" into the first plaster layer. Next, a second plaster layer is applied, after which the walls are painted in the desired color.
- Wall finishing is possible instead of plaster siding, wood, as well as the use of hinged systems for which the frame is pre-arranged.
If it is impossible to insulate the outside, then, if necessary, insulate the walls from the inside. The work is carried out in the same way, but a foil-clad polyethylene film is installed on top of the penoplex as a vapor barrier, then sheets of gypsum board are attached, on which wallpaper can subsequently be glued. The lathing for hanging drywall is fixed with dowels to the wall through the insulation.
Similarly, work is carried out on the insulation of balconies and loggias.... The joints between the slabs are glued with tape. After installing the vapor barrier with foil-clad PE film, we also glue the joints with tape - we create a kind of thermos.
If for finishing if you decide to apply drywall, then you need to choose moisture-resistant sheets of gypsum plasterboard. In addition to the walls, it is also necessary to insulate the floor of the loggia.
Thermal insulation of roofsproduced either at the construction stage, or during the reconstruction process, for example, when transferring a cold attic to a living room.
- roofing material
- lathing
- 3 vapor permeable moisture resistant membrane
- insulation penoplex
- inner lining
- roof 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, with a step of 300 mm.
Penoplex in comparison with its analogue - polystyrene - 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.
