How much Penoplex will replace a brick wall? How much does penoplex replace brickwork? How much brickwork does penoplex replace?

When choosing the thickness of expanded polystyrene sheets that will be used to insulate a building, it is important to consider climatic features the region where it is located, the dimensions of the building and the material from which it is built.

Operational and technological characteristics There are two factors that directly affect the quality of insulation in polystyrene foam – thickness and density.

In general, sheets with a thickness of 50 mm and a density of 25 kg/m3 are considered optimal. This is the type of material that is usually recommended to developers or repairmen who do not know what thickness of polystyrene foam to insulate a house. However, the specified thickness and density are not an inviolable standard and may vary depending on the specific conditions indicated above.

What thickness of brickwork does polystyrene foam replace?

This question can be answered accurately only by having accurate data on the type of brick and the thickness of the masonry. The fact is that different kinds building materials have different ratio thermal conductivity. Moreover, this indicator may differ significantly. Without having the initial data, any calculations are considered approximate.

In general, when answering the question - what thickness of brick does polystyrene foam replace, it is assumed that highly porous polystyrene foam has a thermal conductivity level 10 times lower than standard solid red brick.

IN in this case, multiplying the sheet thickness by the thermal conductivity coefficient allows us to talk about what thickness of masonry it replaces this sheet polystyrene foam For example, a sheet 50 mm thick compensates for at least 0.5 meters of a wall built from solid red brick.

Within this issue, you can additionally provide the following data. Standard Sheet polystyrene foam replaces 1 meter of wall built from sand-lime brick and up to 0.2 meters of silica brick, which itself has a small thermal conductivity coefficient.

You can find out more accurately how much brick replaces polystyrene foam by finding out the exact data on average annual temperatures in your area and design information about the insulated structure.

What is the thickness of foam?

Foam sheets that go on sale are manufactured in accordance with GOST 15588-86. This standard clearly regulates not only the composition and characteristics of the material, but also its overall dimensions.

As a rule, slabs with a length of 1, 1.2 and 2 meters, a width of 1 meter and a thickness of 20 to 500 mm in increments of 10 mm are used in construction. The thickness of foam sheets that are widely sold is: 10, 20, 30, 40, 50, 80 and 100 mm. It should be noted that the most common foam sizes are indicated above. If, for certain conditions, a larger or smaller size is required, it can always be ordered from the manufacturer.

One more important characteristic The density of foam is considered. Density is measured in kg/m3 and can be: 15, 25, 35 and 50 kg/m3. These are the main densities of slabs that can be purchased at wide sale. According to the unit of measurement, the higher the density, the harder the material.

To insulate buildings, it is recommended to use foam plastic with a density of 25 or 35 kg/m3. A material with a lower density does not withstand even small mechanical loads, and a higher density leads to a significant increase in the cost of work, all other things being equal.

Where to start insulating your home?

Considering the above, the first step is to determine the thickness of the insulating layer. Typically, developers choose a sheet thickness of 50 or 100 mm, 25 or 35 density. As practice shows, these are the most optimal characteristics, which retain heat well and do not put much strain on the walls.

In addition, it should be taken into account that foam plastic is under constant action sun rays turns yellow and spoils the aesthetic appearance of the house. Therefore, once you have fixed the sheets to the walls, it is best to protect their surface. To do this, a special mounting mesh is attached to the sheets, after which they are plastered or puttied.

After high-quality insulation existing building, you can see the difference in the amount of energy payments. In general, just by insulating walls with foam plastic, you can achieve a reduction in monthly payments by 20-30%, depending on climatic conditions.

As practice shows, about a quarter of a building’s heat is lost through the roof. Moreover, a poorly insulated roof can cause increased humidity in the house. After all warm air, rising upward, encounters a colder layer of air under the roof. As a result, condensation forms.

Therefore, roof insulation with foam plastic is perhaps one of the most optimal options ensure high-quality heat retention and regulation of humidity levels in the room. Subject to the selection of high-quality foam and correct installation roofing sheets will provide significant energy savings. IN winter time You will be able to save on heating and, in the summer, on air conditioning.

How safe is it to insulate external walls with polystyrene foam?

There are a lot of disputes about the safety and necessity of using expanded polystyrene (or polystyrene foam). The main reason for their appearance is poorly performed insulation work, the use of uncertified material or foam plastic that is not intended for such a role (for example, flammable polystyrene foam).

In fact, high-quality and well-executed insulation of external walls with polystyrene foam guarantees complete safety of the home. Accumulation of dampness, fire danger and other factors do not threaten if the work used polystyrene foam specifically designed for wall insulation.

How to insulate a brick wall with polystyrene foam? What thickness of foam should I use?

The question is quite broad, so it is difficult to provide exact data. If the technology for installing foam plastic sheets for all types of surfaces is almost identical, then the calculation of the material for insulating a brick wall with foam plastic is carried out in each region separately. The thickness of the sheets is primarily affected by climatic conditions region, the area of ​​the house and its thickness brick walls. For example, in the Moscow region for comfortable stay It would be ideal to build houses from bricks 1.5-2 meters thick. In fact, houses from solid brick have a thickness of about 0.7 meters. Depending on a number of factors, foam sheets 50-100 millimeters wide are suitable for insulating such an object.

I heard that for maximum energy savings you need to insulate the ceiling with foam plastic. Is it so?

Insulating the walls of a private house means almost halving energy consumption for heating. This has already been proven in practice. But the positive result will be noticeably reduced if the ceiling of the house is not insulated. From 15 to 20 percent of the heat will simply evaporate, mixing with the cold air. In addition, there is a high probability of condensation formation, which is also not very good for the condition of the house and its inhabitants. Therefore, insulating the floor with foam plastic is an essential part complex works on energy saving and organizing comfortable living in an insulated room.

Due to the fact that the range of insulation materials presented on the building materials market is very large, each consumer can choose the type of insulation that is suitable for him.

One of these insulation materials is penoplex. It's synthetic insulating material for internal and external insulation.

Specifications

• the insulation is resistant to mechanical stress - resists compression;
• moisture-resistant material – does not accumulate moisture;
• practically non-flammable - does not ignite;
• the material acts as a sound insulator - absorbs extraneous noise;
• durable insulation - not affected by fungus, does not rot;
• has not heavy weight– ease of installation.

All of these qualities give penoplex versatility of use and allow it to stand out among other insulation materials. Produced in the form of sheets, which consist of pressed under the influence of high temperature expanded polystyrene.

Penoplex sheets have a little more weight than regular foam, but the thickness is the same: 20 mm, 30 mm, 40 mm, 50 mm.

Most often, the thickness of penoplex determines the area of ​​its application. Note:

There are no locks for installation on sheets with a thickness of 20 mm; they are provided for sheets with a thickness of 30 mm or more.

Application and installation

Facade

The use of penoplex has fairly high quality indicators, but will not be available to everyone, since the price of such insulation is several times higher than the price of all similar products (foam 25 or 35 density).

• To carry out the work you will need:
• clean the walls from dust, debris and grease stains; with help façade roller
• or use a wide brush to prime the base to strengthen it before carrying out the main work;
• made on a special one and then fixed using foam dowels; The final finishing of such a facade after insulation with penoplex is most often- “Bark beetle” or “Lamb”.

All types of penoplex and any thickness are used for walls. The choice will depend on the financial capabilities of the consumer and the characteristics of the building itself.

Most often, the thickness of penoplex determines the area of ​​its application. insulation should be reinforced with façade plastic mesh which will keep decorative finishing and will protect it from blow-outs and chips.

Base

This insulation option provides:

• gluing penoplex around the entire perimeter of the house at the base level according to the type of facade insulation - with glue, but with additional fastening with dowels;
• after this, the insulation must be covered with a special insulation plaster, which can maximally isolate the entire penoplex from the effects of the environment;
• The base is finished in a variety of ways: basement siding, profile sheet, clinker tiles and even decorative plaster.

Take note: To insulate the base, penoplex with a thickness of 40-50 mm is used for maximum protection.

Foundation

The most heat is lost through the part of the house that is closest to the ground - the foundation, so its insulation requires a special approach, and penoplex will be the ideal material for this.

The process of carrying out work on insulating the underground part of a building is very simple:

1. Foundation – bearing wall house, which is located below ground level, is cleared of any remaining solution.
2. Next, waterproofing is applied over the entire area of ​​the base insulated with penoplex. It could be bitumen mastic or dry waterproofing mixture. The work is best done with a wide brush. (On how to properly waterproof strip foundation with your own hands, you can read in).
3. Next comes the process of installing penoplex - gluing each sheet separately onto the same mastic or special glue for insulation. Foam dowels are used as additional fasteners. The only condition is a continuous coating, which will complicate the escape of heat and prevent the accumulation of condensation.
4. Penoplex must be closed waterproofing film and only then carry out the accompanying drainage work.

It is best to use penoplex for insulation maximum thickness- 50 mm.

Balcony

This part of the apartment is responsible for preserving the heat that escapes through balcony block, so here you need to act with full responsibility.

Work on insulating a balcony with penoplex is carried out in stages:

1. Leveling all insulated surfaces.
2. The foam is fastened by driving in fasteners - dowels for insulation.
3. Before decorative painting penoplex is completely plastered and kept for 12 -24 hours until completely dry adhesive mixture.

At using PVC or MDF lining the process will be slightly different:

• the penoplex is fastened by driving in fasteners - dowels for foam plastic;
• foam sheets are very quickly and reliably fixed between the sheathing;
• finishing the balcony with clapboard does not require an additional insulating layer.

Take note: To insulate the balcony, penoplex with a thickness of 20 or 30 mm is used to increase the usable area.

Floor

Extruded polystyrene foam occurs by joining sheets using existing grooves.

Most often, the thickness of penoplex determines the area of ​​its application. According to the technology, the entire insulation is covered with a waterproofing film, which is very rarely done by craftsmen due to the inconvenience of installing the screed. Next comes the reinforced layer - masonry mesh, which is laid over the entire surface to be reinforced, and everything is poured cement screed for the floor.

If you plan to install a wooden floor, then sheets of Penonlex are laid between the joists, having previously covered the floor with a waterproofing film.

Installing a heated floor with insulation such as penoplex is completely safe even without the use of additional insulation.

Floor insulation in apartment building will also create additional layer soundproofing. It is advisable to use insulation sheets of maximum thickness - 40-50 mm.

Considering all of the above, we can conclude that such insulation as penoplex can be used in any premises and under any conditions. weather conditions. The options described are not all; for example, penoplex can be used to insulate even a garage. The only condition will be the thickness of the foam sheet, on which the quality of the insulated surface directly depends.

We bring to your attention a comparison video different types penoplex:

Polystyrene foam (expanded polystyrene) and mineral wool are the most popular today thermal insulation materials. Each of them has its own advantages and disadvantages, and has its own scope of application. Foam boards are recommended for use for external thermal insulation walls, mineral wool - for roof insulation and as a heat insulator during installation curtain facades. However, there is an opinion that these materials are interchangeable. Is it so? Let's try to figure it out.

Foam plastic: pros, cons and application features

Polystyrene foam - foamed plastic material - has an extremely low thermal conductivity coefficient. This is the best thermal insulator on the planet. It is estimated that a foam plastic board 10 cm thick in terms of heat-shielding properties replaces 40 cm of wood, 60 cm of aerated concrete, 90 cm of expanded clay concrete, 150 cm of hollow brick, 400 cm of reinforced concrete.
Foam plastic also wins in comparison with mineral wool: 10 cm of polystyrene foam is equivalent in thermal protection to 16 cm mineral wool.
But polystyrene foam cannot protect you from noise. It is no sound insulator.

As for vapor permeability, this characteristic varies depending on the density of the material. Low-density foam is close to cotton wool in terms of vapor permeability, high-density foam allows steam to pass through, although with difficulty, so it can be used to insulate only very dense walls.

Regarding the environmental friendliness of polystyrene foam consensus No. Disputes over the toxicity of polystyrene have lasted for decades. Soviet scientists also proved that under certain conditions this material is capable of releasing toxic styrene into environment. However, the results of modern laboratory research they say that high-quality polystyrene foam is absolutely harmless. The tiny amount of styrene that it releases has no effect on the human body.
Advice: before purchasing, be sure to check the residual styrene content - the value of this indicator should be in the range of 0.01-0.05%.

Its service life also depends on the quality of the foam. The most durable are the pressless brands PSB and PSB-S. They do not change their properties for 10-40 years. Extrusion lasts even longer - up to 80 years.
The most a big problem expanded polystyrene – high flammability. Styrene foam can catch fire with just a spark. When exposed to fire, it melts and emits black toxic smoke. To solve this problem, special additives began to be introduced into foam plastics - non-flammable and flame-extinguishing additives. This is how it appeared new type expanded polystyrene - self-extinguishing grade PSB-S. This material cannot be ignited by a spark, but it has no protection from fire.
Important: all types of polystyrene foam must be used exclusively for external insulation.

Mineral wool: main properties, advantages and disadvantages

Mineral (“stone”) wool – fibrous material, obtained by melting igneous rocks. The advantages of mineral wool are predetermined by the properties of the raw materials.

The undoubted advantage of this mineral insulation is fire resistance. The melting point of mineral wool is 800C. It not only retains all its properties in the event of a fire, but also prevents the spread of fire.
Mineral wool ranks second in terms of thermal insulation properties after polystyrene foam, but at the same time it is highly hygroscopic - in a humid environment its heat-shielding properties deteriorate significantly. But unlike polystyrene foam, mineral wool does not interfere with the passage of steam - the condensate that falls freely passes through its fibrous structure and evaporates from the surface.

Another advantage of mineral insulation is its excellent soundproofing properties. Stone wool creates a reliable barrier to the passage of sound waves.
One of the main disadvantages of this material is its heavy weight. When calculating the cost of insulation, the cost of loading/unloading and delivery to the construction site should be taken into account. Besides, mineral slabs require more powerful supports, while foam adds almost no weight to building structures.
Regarding environmental safety: there is evidence that one of the fractions of fibers that form mineral wool has carcinogenic properties, and those used in its production binder material releases a highly toxic and extremely harmful substance to humans - formaldehyde. Like polystyrene foam, mineral insulation is recommended for external insulation.

Which is better: polystyrene foam or mineral wool?

Let's compare these two materials according to the main indicators:

• Thermal insulating properties. In terms of thermal conductivity, polystyrene foam has no equal. Minvata also loses to him.
• Fire safety. Mineral wool is highly resistant to fire, which cannot be said about polystyrene foam.
• Vapor permeability. Mineral wool is approximately 10 times more vapor permeable than polystyrene foam.
• Hygroscopicity. Polystyrene foam can be used in a humid environment without losing its consumer properties. Stone wool is critical to moisture.
• Price. Foam plastic wins here - it is the cheapest building material.
• Weight and ease of installation. Polystyrene foam weighs much less than mineral wool. It is more convenient to process, but more difficult to join.
• Environmental Safety. Both materials are not recommended for interior work.
• Biological and chemical resistance. Mineral wool is resistant to all organic matter and fungi. Expanded polystyrene is critical to the effects of organic solvents, but is not susceptible to

As you can see, choosing insulation is a complex and multifaceted task. When solving it, you should take into account specific conditions and your own priorities. Give preference to proven insulation systems. Don't forget about the selection optimal thickness thermal insulation.

I recently insulated my balcony, if you're interested.

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 with 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 is also the 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?

Which 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 of 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:

• lower thermal conductivity coefficient.
• 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 key factor when 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). The slabs intended for insulation of foundations have higher compressive strength values ​​- 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 in the range from -70 to +75 degrees Celsius, which allows the use 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 of solid (conditional) masonry).

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