Standard sizes of Penoplex. Types and characteristics. Comparison with analogues.

Extruded polystyrene foam (penoplex) has established itself as a good and convenient thermal insulation material.

Before starting construction work with penoplex, you need to find out how much material is required.

This thermal insulation material is produced in slabs of various sizes and thicknesses.

To make an accurate calculation of the amount of penoplex, you need to know the dimensions and thickness of these plates. Below are the sizes of extruded polystyrene foam boards.

Dimensions of penoplex sheet depending on thickness, density and purpose

Useful tips

Most homeowners turn to external rather than internal wall insulation with penoplex. This is explained by the fact that the second option hides the usable area of ​​the room.

When decorating floors after insulation, they often turn to grouting. For this it is better to use sandpaper. You can proceed to this stage after the reinforcing layer has completely dried. Despite the strength of penoplex, you should be careful when working with it, since this material can still be damaged or broken.

Select high-quality and most effective glue for penoplex. A special adhesive foam is ideal for laying this insulation: it firmly and tightly attaches the material to the base and holds it quite reliably. Make sure that the thickness of the penoplex for wall insulation is at least 5 cm. Ensure that the insulation is securely and tightly attached to the base. Use both nails and glue.

When installing insulation, you cannot do without a profile, especially when it comes to installing a frame structure. It is advisable to purchase a bubble or laser tool, which is both easier and more convenient to use.

To make the external insulation of a house more effective and complete, it is recommended to insulate the foundation in advance (the basement can also be insulated along with it). In this case, all the work is done quite simply: first you need to dig out the foundation, clean it of any dirt, and then glue the foam sheets. After this, the base can be buried.

When installing penoplex on the facade of a building, you must ensure that the panels overlap each other by about 10 cm. This way you can avoid the formation of cracks.

Extruded polystyrene foam is a strong and durable material, but it does not tolerate contact with the following substances:

• gasoline, diesel fuel, kerosene;
• acetone and other ketone solvents;
• formaldehyde and formaldehyde;
• benzene, xylene, toluene;
• various esters;
• polyesters;
• coal tar;
• oil paints.

It is most convenient to apply glue to materials using a notched trowel. In this case, it is advisable to make the adhesive layer no more than 10 mm.

Facade penoplex glued to the ceilings needs to be bandaged vertical seams. This technology is very similar to laying bricks.

If you are going to plaster a wall insulated with penoplex, then you should first apply a base composition with a reinforcing mesh. The density of the latter must be at least 145 g/m2. Make sure that the size of the overlap is about 10 cm. Next, you need to lay a leveling plaster layer (its thickness should be at least 5 mm). Only then should the thermal insulation material be covered with decorative finishing.

If you are sheathing a house with penoplex in 2 layers, then first glue the starting layer, and on top of it place the next layer with a slight offset. Before this, it is worth treating the slabs with a roller.

Before installing insulation, old coverings should be removed only if they have noticeable damage or crumbling areas. If the previous finish does not have any defects or complaints, then penoplex can be placed on it.

Penoplex can be installed on a variety of substrates. It can be safely used for a private/country house or city apartment. In addition, you can easily install this insulation not only on walls, but also on the roof/ceilings.

Experts advise not to rush to insulate the house until it shrinks completely. Otherwise, the layer of plaster will become cracked and may begin to crumble. To carry out thermal insulation work, it is necessary to select only high-quality materials and tools.

Leveling the bases for laying penoplex can be done with plasterboard. However, the presence of this material will reduce the additional space in the room. Owners of city apartments with uneven floors often turn to such solutions.

If you decide to lay penoplex on a wall made of foam concrete, then it will come in handy to install a vapor barrier material. These components are not needed only if we are talking about bases whose structure is not porous.

Material package dimensions and number of sheets in each package

Penoplex is sold in packages in the form of a stack of sheets. The length and width of the package coincide with the standard dimensions of the insulation sheet and are equal to 120 cm and 60 cm.

Table 1. Dependence of sheet thickness on their quantity in the package Sheet thickness (cm) Number of plates (pcs) Packaging thickness (cm) Total area of ​​all insulation sheets (m2) 2204014.43144210.08410407.258405.7667425.0485403.6104402.88123362.1615 2301 .44

Non-standard Penoplex roofing sheets, which are 240 cm long, 60 cm wide and 10 or 15 cm thick, are packaged according to the same principle: 4 or 2 pieces. A package of sheets with a thickness of 10 cm will have an area of ​​5.76 m2, and a package of sheets with a thickness of 15 cm will have an area of ​​2.88 m2.

Do not forget that part of the insulation will be spent on cutting and trimming, so buy material with a margin of 10-20 percent. A small supply and scraps of penoplex will help you with routine repairs.

Penoplex, packaged in the form of a stack of sheets, is not damaged during transportation, it is easy to store and can be moved without special equipment. Knowing the required insulation area, you can easily calculate the amount of insulation for any construction and repair.

No comments yet

When choosing a material for insulating a house, you will definitely come across the name “PENOPLEX” - this is one of the most popular insulation materials on the Russian market. It is quite natural that there are a lot of rumors around the material: they say it is harmful, does not cope with thermal insulation, and is unreliable. To thoroughly understand this issue, it makes sense to separate the wheat from the chaff and examine in detail all the characteristics of thermal insulation boards.

Installation technology

When laying on horizontal surfaces - floors, flat roofs - the slabs are simply laid on a flat surface. The surface should be without sharp changes, the maximum deviation is 2-3%. This requirement must be met so that voids do not form. When laying, we monitor the joints; it is advisable to glue them (you can use tape) or fill them with the same foam/glue on which the slabs are attached.

When using Foam plastic for insulation of balconies

If two layers of thermal insulation are laid, it is positioned so that the EPS slabs of the second row overlap the seams of the lower one. They also say that the slabs are laid with alternating seams or “staggered”.

When mounting on vertical surfaces, double fastening is used:

• Glue or adhesive foam is applied to the plane.
• Additionally fixed with umbrella dowels.

According to the technology for installing slab insulation on facades, umbrella dowels are installed at the junction of two sheets (any two sheets) and two additional fasteners in the plane of the sheet. That is, there are at least 8 fasteners per sheet (indicated in red in the figure). More is possible. Less - no. Unless, of course, you want the insulation and finishing to come off. If the winds in the region are strong, it is better to put more. To insulate the inside, you can install less (see diagrams below).

Schemes for installing umbrella dowels when installing Penoplex on vertical surfaces

During installation, on the outer slabs and around openings, we install fasteners more often: three to four elements per slab. To keep the insulation rigid in the corners of the openings, a mesh is attached to it before plastering. It is attached at an angle of about 45°, securing the joint. Under such conditions, there will be no problems with finishing inside or outside.

If plaster, facade tiles, finishing stone and other heavy materials are subsequently applied to Penoplex, before installation, care must be taken to improve the adhesion of the material to the wall and to the finish. Even if you are installing a Penoplex Wall with stripes, it is better to add roughness to the slab using a metal brush. And from both sides. If the wall is smooth, it also doesn’t hurt to add roughness - for better adhesion.

If the wall is smooth, it also needs to be processed by putting a metal attachment on the drill

To work with Penoplex, a special adhesive mixture is recommended: Ceresit ST 84, illbruck PU 010, Titan 753, Ceresit CT-85, Kreisel 210 and 220, Baumit ProContact, STO Baukleber, Soudal Soudabond, Penosil Fix and Go, Den Braven, Krass.

What is this. History of the creation of the material

The material first appeared back in 1941, when the DOW CHEMICAL company (USA) patented a fundamentally new product with high thermal insulation properties and moisture resistance. The production of the material was put on stream, but initially it was manufactured only for the needs of the Navy. Due to its resistance to humid environments, Penoplex was used for the production of life rafts. After some time, the material began to be used in refrigeration units. Penoplex occupied its rightful niche only in 1950, when it began to be used in construction.

It is curious that in the US construction market the material is known under the brand name STROYFOAM. Penoplex is a Russian brand that appeared only in 1988. What is Penoplex? Essentially, it is foamed polystyrene, which is produced on extrusion machines. In its structure, the material resembles polystyrene foam, which is familiar to many, but has a denser structure and, accordingly, better characteristics.

Details about the characteristics

Extruded polystyrene foam has gained popularity due to its excellent performance and quality characteristics.
Extruded polystyrene foam has gained popularity due to its excellent performance and quality characteristics. In many respects, the insulation is superior to all known thermal insulation materials.

What is Penoplex made of? Compound

We have before us a completely artificial material, which is made from chemical components mixed in certain proportions. The technology involves using a temperature of 140 degrees, which causes the ingredients to melt and foam, forming porophores. If we talk about specifics, the following materials are used in production:

Polystyrene. Ground perlite. Citric acid. Tetrabromoparaxylene. Barium or zinc stearate. Sodium bicarbonate.

The use of such components in certain proportions forms a strong cellular-porous structure filled with gas.

If you want to stick it on the wall...

If, for some reason, a decision is made to insulate the walls with penoplex (possibly due to the manufacturer’s statements about the great durability of the material...), then the wet facade technology must be done at least correctly.

• The torn insulation layer from below and above must be protected by appropriate strips.
• A flat, durable wall surface is provided on which the sticker will be applied.
• The sheets are glued with the appropriate glue, with the maximum-largest area of ​​close contact with the wall on the glue... And also much more....

Advantages and disadvantages of heat-insulating material

Like any building material, this insulation has its strengths and weaknesses. The fine balance of price and quality makes it competitive and distinguishes it from numerous analogues. Let us immediately note that it is not worth singing odes of praise to Penoplex: despite many undeniable advantages, there are also disadvantages.

If you conduct an impartial analysis of the characteristics, you will get the following picture. Pros: High thermal insulation rates. Absolute neutrality to a humid environment. Convenient installation. Easy to process. Multifunctionality. Durability (subject to certain conditions). Soundproofness. Cons: Low fire safety of unmodified material. Low vapor permeability. Sensitive to aggressive substances: gasoline, acetone, oil paint. Unstable to ultraviolet radiation. Destroys in direct sunlight.

It is worth noting that the material has different densities, which determines the scope of its application. Usually the manufacturer indicates this data on the packaging, significantly simplifying life for inexperienced builders.

So, according to their characteristics and scope of application, the following types of extruded polystyrene can be found on the market: For roofing. This material is suitable for increasing the thermal insulation of roofs and is used in commercial and residential buildings. The density of this category varies between 28-33 kg/m3. For walls. Suitable for insulating facades and interior spaces.

Here the density indicators are 25-32 kg/m3. For the foundation. The density of the material varies between 29-33 kg/m3, area of ​​application: initial stages of construction, arrangement of basements. “Comfort”. Here the density indicators look like this: 25-35 kg/m3, due to its characteristics, the material is the optimal solution for multi-story buildings (apartments, balconies, loggias). Type “45”. This category is the densest on the market: 35-47 kg/m3.

The area of ​​application of the material is to improve the properties of a runway or road surface in conditions of extremely low temperatures. Considering that the cost of the material directly depends on its density and thermal insulation, knowledge of these features will help you purchase a suitable material and save money.

Coefficient of thermal conductivity

Low thermal conductivity allows for effective insulation. The coefficient is almost 10 times lower than that of high-quality mineral wool. Penoplex has a thermal conductivity coefficient at 25±5°C of 0.032 W/(m•°K).

Low vapor permeability

The vapor permeability of the material is almost zero.

This allows for better thermal insulation, but can lead to condensation, so it is not recommended to use penoplex when insulating baths and saunas.

Moisture resistance

The material has a high moisture resistance, which allows such insulation to be carried out without additional waterproofing. Moisture absorption is practically zero.

Dimensions of insulation boards

Penoplex is produced in the form of slabs, with the following external parameters: length - 1,200/2,400 mm, width - 600 mm. Thanks to its porous structure, the material has a relatively low weight even with impressive dimensions, and is easy to process.

Let's conduct a comparative analysis with other popular insulation materials that are found on the domestic construction market.

Where is Penoplex made? Reliable manufacturers you can trust

Penoplex is produced in Russia, so the material is sold in an affordable price segment. If we talk about brand representative offices, you can pay attention to the following cities:

• Kirishi . The production line has been operating since 1998, specializing in the production of standard size insulation. Currently, there are four lines involved. Total capacity up to 600,000 m3 annually.
• Perm branch . The plant was launched in 2005. Now, this is the most productive enterprise, supplying the market with about 650,000 m3 annually.
• Novosibirsk . The enterprise was launched for residents of the Siberian region of the country, specializing in the production of Penoplex with increased thermal insulation and water resistance.
• Taganrog . The plant produces about 500,000 m3 of insulation annually and, accordingly, fully supplies the residents of the Southern and Central regions with products.

It is worth noting that the products of these branches are subject to mandatory certification and undergo multi-stage quality control at all stages of production.

Available analogues. What is the difference? Which is better and warmer?

If you compare these materials, you must take into account their scope of application.

For example, mineral wool is definitely not suitable for a foundation or basement: it absorbs moisture well, which leads to weight gain. Accordingly, the insulation slides down, exposing the walls. To avoid these problems, you will have to install additional moisture insulation, and this proportionally increases costs. However, in terms of heat and sound insulation, Penoplex loses to mineral wool, although the latter material looks more difficult in terms of installation. Penoplex or Penoplast Both materials do not absorb moisture, therefore they are equally suitable for insulation of basements.

Thermal conductivity indicators are better for Penoplex, but only slightly. It is worth noting that polystyrene foam can be classified as an eternal material, and the service life of Penoplex declared by the manufacturer is 50 years. Therefore, for internal and external insulation, both materials can be used with equal efficiency, but if service life plays a decisive role, it is better to give preference to polystyrene foam. Technoplex or Penoplex These are two materials that are almost identical in their properties.

Here you can observe the same indicators of mechanical strength and bending resistance: 250 kPa and 0.4 MPa, respectively. If we talk about resistance to sub-zero temperatures, then Technoplex looks warmer - the operating temperature of the material is -70 degrees Celsius, however, such temperatures are difficult to meet in most regions of Russia. The thermal conductivity of the insulation is the same: 0.031 W/mK, but Technoplex is more resistant to humid environments. Styrex or Penoplex There are no fundamental differences between these materials, so they have an identical scope.

Here we can highlight the following difference: Stirex is more resistant to bending deformation, but is more expensive to purchase. In addition, Stirex is more suitable for insulating rooms where there is a significant difference between external and internal temperatures. Izolon or Penoplex Thanks to its structure, Izolon is ideal for insulating floors and roofs, increasing the thermal and sound insulation of rooms. However, for walls it is better to use Penoplex as a material that is more convenient to install.

Roof thermal insulation

The work begins with laying insulation on the rafter system.
Measures to insulate this structural element are carried out either during construction or during the reconstruction of an old facility. Insulation is often carried out to turn a cold attic into a living space. Before starting work, you need to prepare the following materials:

• metal tiles or other roofing solution;
• sheathing;
• vapor-permeable moisture-resistant membrane;
• insulation;
• internal lining;
• rafter structure.

Work begins with laying insulation on the rafter system. The material is placed in a checkerboard pattern. After this, you need to lay a vapor-permeable membrane on it. Next, using longitudinal slats with a thickness of at least 40 cm, the 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 this, you can proceed to securing the transverse slats. Then, after placement, the roofing material is fixed on them. It is permissible to use metal tiles or any other.

Roll solutions for continuous flooring can be a good alternative

Penoplex differs from another popular insulation product - penoflex - by its high cost. However, this disadvantage is compensated by its excellent characteristics. It is ideal for use under plastering systems.

Penoplex is one of the best materials for creating effective thermal insulation. If you constantly feel cold in your home, then using it can solve this problem. There are significant costs involved in carrying out the work. But they are offset by savings on heating rooms. Proper implementation of the procedure minimizes heat loss and ensures comfortable living.

Fire safety. Is the insulation burning or not?

The answer to this question is clear: yes, it burns. Perhaps it is this feature that prevents the widespread spread of Penoplex. However, on the building materials market, there are products marked “G1” and “NG”, which means low-flammable and non-flammable material.

In this case, antiperen is used - a substance that prevents the spread of fire. It is worth noting that it is spread, not fire. Of course, for Penoplex to ignite, a fairly high temperature will be required, however, the essence is the same: the material is flammable!

The difference between penoplex and polystyrene foam

Both expanded polystyrene (EPS) and polystyrene foam (EPS) are produced from the same raw materials. However, thanks to a special manufacturing technology, penoplex receives heat treatment during the production process, making it much stronger. This circumstance allows EPS boards to better withstand mechanical loads and not collapse in those circumstances where the foam plastic is deformed, crumbles and ceases to perform its functions.

Moreover, given its specific structure, penoplex has lower vapor permeability, which means it retains heat better. And experiments prove that extruded polystyrene foam is superior to polystyrene foam and other insulation materials in terms of thermal characteristics. A good example: 20 mm thick penoplex can retain heat with the same efficiency as 30 mm polystyrene foam, 40 mm mineral wool or 400 mm thick brickwork.

Is polystyrene foam harmful to health?

In principle, Penoplex is an environmentally friendly material, provided that the material is created without violating production technology. However, given that we are talking about an artificial material, chemical components can evaporate under the influence of certain factors, for example, prolonged exposure to direct sunlight. Therefore, Penoplex is not found on the walls in its pure form and is always covered with finishing materials.

In addition, when the material burns, it releases acid vapors, carbon dioxide and other dangerous substances, including hydrogen chloride. Accordingly, in the event of a fire, there is a direct threat to human life.

Hexobromocyclododecane, which is a bioaccumulative toxin and is currently permitted in our country, but has been prohibited for use in the European Union since 2015, can be used as a flame retardant.
