Penoizol application in construction. Sheet penoizol - production technology


Due to the constant and rapid increase in electricity and heating tariffs, most people are trying to save money by using energy-saving technologies. More recently, sheets of expanded polystyrene, polystyrene foam or mineral wool were used for this. However, since progress does not stand still, the above materials have been replaced by penoizol.

This article will discuss the main competitive advantages of this technology, as well as its characteristics and scope of application.

Penoizol is a liquid insulation material that is used in construction and installation works (construction and installation works). Unlike standard insulation materials (mineral wool, extruded polystyrene foam, etc.), this material has a liquid structure, thanks to which it can be easily poured into a cavity in the wall, into interpanel seams or cavities of reinforced concrete floors.

To make penoizol, a special resin is used, which, when exposed to chemical reagents (foaming agents based on aluminum powder), creates a porous structure that perfectly retains heat.

Depending on the place of application, penoizol is manufactured with a density of 10 to 30 kg per cubic meter. Moreover, its thermal conductivity reaches 0.028-0.038 W/m².

For example, 50 mm of penoizol replaces 125 mm of mineral wool, or 2132 mm of concrete. Based on this, it follows that this material has high technical and economic indicators, which makes it a leader in the insulation market.

Scope of application of modern insulation "Penoizol"

This technology demonstrates high results when pouring:

  • into the air space formed between two walls;
  • between roofing covering and rafter system;
  • in a frame on which partitions or false walls are assembled from gypsum plasterboard sheets;
  • between the external upholstery (siding, lining, corrugated sheets, etc.) and the wall;
  • into the space between the concrete subfloor and the OSB sheets.

As can be seen from the above list, the scope of penoizol is quite extensive. However, why is this material so popular? To do this, it is necessary to consider the main advantages of this technology.

The main advantages of insulating a house, apartment or office using penoizol

  1. Due to the flowing structure during pouring, the material fills all cracks and voids as it is supplied under pressure.
  2. Effectively retains warmth in winter and coolness in summer period time, since its thermal conductivity reaches 0.028 W/m². For comparison, the thermal conductivity of mineral wool at a density of 125 kg per cubic meter is 0.07 W/m², which is more than 2.5 times higher than that of penoizol.
  3. Absence of cold “bridges” that arise when insulating with sheet insulation.
  4. Quick installation. This insulation is prepared directly on site and is applied very quickly, since it does not require preparing a base or leveling walls or floors.
  5. This material It is made from environmentally friendly materials, which allows it to be used even in children's rooms.
  6. Does not spread fire. When the electrical wiring is shorted to this insulation Unlike foam plastic, the source of the flame goes out immediately.
  7. When applying penoizol there is absolutely no unpleasant odor.

Penoizol application technology

This material in its structure is a thick urea-formaldehyde foam made of white polystyrene foam. This material is pumped under pressure into the necessary cavities, the higher the pressure, the better the insulation of the object.

After penoizol enters the required cavity, a polymerization process occurs, due to which it is released large number air bubbles, which precisely ensure the low thermal conductivity of the material.

After completion of the polymerization process, penoizol gains strength and retains its porous structure for many years.

Conclusion

Penoizol is a highly effective material for insulating walls, floors or roofs, with low thermal conductivity, long service life and an affordable price.

In the process of insulating your own home, it is necessary to take into account a large number of nuances, all this in order to save electricity and fuel in the future. Therefore, manufacturing companies are trying to offer insulation materials that have all the necessary characteristics.

For recent years Because of its popularity, the Penoizol trademark has become a household name. The insulation of this company is a competitor to expanded polystyrene and is produced in several forms: liquid penoizol, sheet and granular. The first type is used more often than others, as it is profitable and easy to use.

This insulation is used to insulate structures of any complexity: a room, the facade or roof of a building, an attic, a garage or a basement. And you can handle the installation yourself, without involving specialists.

Let's look at the features of penoizol, reviews of those who insulated their homes with it, the advantages and disadvantages of the material.

Penoizol is widely used as insulation for houses built and under construction. It is used for thermal insulation of walls, ceilings, roofs, floors and ceilings between floors.

Penoizol is essentially a polystyrene foam that has undergone modification.

Penoizol has acquired improved thermal insulation properties, while the material does not emit compounds hazardous to health, is not afraid of fire, and is resistant to moisture.

The underlying components of penoizol make it similar to expanded polystyrene, but with smaller cells. This insulation, which looks like a marshmallow, contains phosphoric acid, urea resin and a foaming agent.

The insulation is installed by spraying using a special device. However, for small jobs, polystyrene foam (penoizol) in cylinders is used. When working with the device, all the components that make up the heat insulator are combined, and then the resulting mixture is fed outside to fill all existing cracks and cavities.

It takes 2-3 days for the foam to gain the necessary strength, but it begins to harden within 10-15 minutes after installation. Instantly regains its original shape after mechanical impact due to elasticity and 90% air content.

This heat insulator is also called thermal insulation, eco-insulation, jellied, liquid and urea foam.

There are three types of urea foam:

  1. Sheet penoizol , what is this? The manufacturing process of this heat insulator is that the liquid is poured into a mold, and after hardening, the resulting material is cut into sheets required thickness. The insulation is subjected to finishing and installed on the outside of the building. In addition, this type of penoizol is used to cover floors or insulate structures under construction.
  2. Granular insulation penoizol (foam-insulated or thermally insulated crumbs) - used to cover the foundation, floors, interfloor and inter-wall ceilings. Such penoizol is made by crushing the polymerized material into small elastic granules (10-15 millimeters). Thanks to this insulation, you can save your budget, since the crumbs double when crushed.
  3. Liquid penoizol - most popular today. The insulation is prepared immediately before use and is suitable for filling confined spaces in order to create a sound and heat insulating layer in walls, sandwich panels and frame-type buildings. During the repair process, liquid foam insulation is used to fill cracks, gaps and cavities.

Penoizol characteristics table

Among all traditional insulation materials, users highlight penoizol, the characteristics of which allow us to classify it as high-quality and practical building materials .

Characteristics of penoizol as insulation:

Thermal conductivityThe thermal conductivity of foam glass and penoizol are similar: 0.031-0.041 W/m*s.
Moisture resistancePenoizol absorbs 10-20% of moisture per day, which evaporates without affecting quality.
Biological resistanceThe material is not afraid of bacteria and rodents.
Fire resistanceThe insulation is classified into groups G-1 (does not burn well), B-2 (does not melt), D-1 (does not emit smoke) and T-1 (non-toxic).
Chemical resistancePenoizol is resistant to aggressive environments.
Vapor permeabilityStructures sprayed with foam insulation “breathe” due to the hygroscopicity of the material.

The table shows the most important qualities of a thermal insulator, thanks to which the home becomes warm, comfortable and safe.

However, among the characteristics of penoizol as insulation, the following important details stand out:

  • the cost of penoizol is comparable to the cost of mineral wool and lower than the price of foil insulation;
  • the material is universal and has a high level of adhesion - the composition of penoizol allows it to be used for structures of complex and carved shapes;
  • during installation and during further operation, penoizol does not emit hazardous chemical compounds;
  • penoizol has high noise absorption rates;
  • due to its softness, penoizol (pictured) closes all existing cavities and cracks;
  • The approximate service life of penoizol is from 30 to 50 years.

Disadvantages of penoizol

Penoizol, like any product or service, has its own characteristics, which buyers classify as disadvantages:

  1. High-quality installation of penoizol is possible only at a temperature not lower than +5°C.
  2. To use insulation, you need to hire specialists, purchase or rent special equipment, which requires financial costs.
  3. Due to the high level of moisture absorption, this heat insulator cannot be used for the underground part of the foundation and under the screed.
  4. Due to its density, the insulation breaks easily.
  5. The material shrinks by 0.1-5% (except for installation in the space between walls).
  6. If the manufacturer has used low-quality resin in penoizol, the material may emit phenol-formaldehyde vapors.

Foam plastic or penoizol

According to customer reviews, penoizol is the most profitable and practical means for insulating rooms.

Penoizol is safer and has low thermal conductivity compared to polystyrene foam. The fact that knowledge and equipment is important for installing penoizol does not stop buyers, since its characteristics are better than those of foam plastic. If your budget is limited, you can buy polystyrene foam, since it is cheaper than penoizol, but it is better not to skimp on insulation.

On the building materials market there are products with a cellular structure, an example is penoizol. Not only professionals create it with their own hands from scrap materials, but also ordinary people who have some experience. This is an inexpensive raw material that requires the use of simple equipment. For this reason, this insulation has a low cost.

Features and description of the material

The material is a modified foam. Its main characteristics are:

  • resistance to fire;
  • good thermal insulation characteristics;
  • installation by spraying.
Penoizol has good resistance to fire

The basis is made up of three components. This is orthophosphoric acid, urea resin and a substance with foaming properties. The specified ingredients are mixed in exact proportions and the device is installed. A mixture resembling jelly is formed. She has white shade. Under the influence of compressed air, it moves outward. She:

  • fills any space;
  • ensures tightness;
  • forms a lush foam after hardening.

Curing requires several steps. After application, the composition sets slowly. This takes approximately 15 minutes. After 3 hours the foam becomes a little hard. But this is not enough for it to fulfill its functions. The material takes its final form after 3 days.

In its finished form, it is not solid, but liquid penoizol that is formed. Some home craftsmen are trying to make it with their own hands, since it has good technical characteristics and is considered easy to manufacture. The material is elastic and easily restores its shape after any mechanical stress. It contains up to 90% air. Outwardly, it resembles expanded polystyrene, but differs from it in its fine cell structure.

The improved properties of penoizol have made it popular in the field of insulation of private houses. It finds application in thermal insulation complex structures, interfloor ceilings and gender.

Key varieties

There are various types urea foam. All of them are suitable for thermal insulation of buildings.


Penoizol can be used for thermal insulation of complex structures, interfloor ceilings and floors.

Main types:

  1. Liquid penoizol. Received the greatest distribution. It can be cooked directly on construction site, because it is very convenient. Material used for thermal insulation various designs, as well as for the purpose of repairs. Foam is poured into a confined space to form additional sound insulation in frame buildings. If we're talking about O repair work, penoizol in liquid form is used to fill cracks and gaps.
  2. Granular penoizol. It has several names: foam insulation crumb, thermal wool. It is available in the form of elastic granules. During manufacturing, the polymer is crushed into fractions up to 15 mm in size. Volume finished material after grinding, it doubles in size compared to the original amount. This good option to save on installation costs. Granular penoizol is used to fill the cavity between walls and for laying on the floor.
  3. Sheet foam insulation. The liquid material is poured into a special mold. After cooling, it is cut on special machines or simply by hand until it is given the required thickness. After this, dry, carry out machining. The product is used to insulate buildings under construction. Installation is carried out using dowels with outside walls Decorative panels or siding are laid on top. In addition, the slabs are laid between the joists on the floor.

More information about the production of penoizol:

Penoizol can have different densities depending on the manufacturer. It varies on average from 6 to 35 kg per cubic meter.

Technical indicators

Compared to traditional insulation, penoizol has many advantages. The main characteristics worthy of attention include:

  1. Thermal conductivity. The only one low rate- 0.041 W/m/K. To ensure good performance, it is enough to lay a layer 10 cm thick.
  2. Soundproofing. Noise absorption is at a quite decent level. It is approximately 65%.
  3. Fire resistance. The flammability group to which penoizol belongs is designated G-1. Its flammability category is B-2. This indicates that it will not melt when exposed to fire. Upon reaching high temperatures the material will begin to evaporate, but will not be produced toxic substances. Given that open fire 10 times less smoke is generated compared to polystyrene foam.
  4. Resistant to chemical components. The insulation does not react in any way to aggressive environments. This primarily applies to organic solvents.
  5. Resistance to humidity. Penoizol has the ability to absorb moisture well, but it gives it away with equal success. The characteristics of the material are not affected. It is capable of absorbing up to 1/5 of moisture. Penoizol subsequently evaporates it. To prevent mold from forming on the wall, install a ventilation gap. The heat insulator absorbs approximately 20% of moisture throughout the day.
  6. Vapor permeability. The insulation in question is hygroscopic, and therefore allows the walls to breathe. Air circulates freely throughout the structure.

Penoizol has good vapor permeability, which allows the walls to breathe

Other characteristics include biostability. This means that penoizol is not afraid of fungi, pathogenic microflora, and domestic rodents. The material is soft, so it adheres to any uneven surfaces close. It fills any gaps. With a linear deformation of 9%, the compression strength is 0.5 kg per square centimeter.

They started producing penoizol relatively recently, so we can only talk about its durability. It appeared on the market only 50 years ago. But manufacturers claim that it can last up to 30 years. Environmental friendliness is another advantage, since toxic compounds are not released either during installation or during operation.

Disadvantages of the product

The main disadvantage of penoizol is that it produces sediment in the range of 0.1−5%. These indicators are better for the material that is between the walls under some pressure. Other disadvantages include:

  1. Low tensile strength. It's pretty easy to tear.
  2. Increased moisture absorption. In some situations this is a significant drawback. This feature prevents the use of this type of foam in the underground part of the foundation and when constructing a screed. It is necessary to lay additional waterproofing.
  3. The need to use special equipment. This is true for liquid forms of foam.
  4. Installation temperature requirements. It should be above +5°C. High-quality foam will only be obtained if this requirement is met. In addition, liquid urea foam can release phenol-formaldehyde during installation. This is possible if it contains low-quality resin.

Selection criteria and equipment purchase

In most cases, liquid penoizol is chosen when it comes to domestic use. It is applied using special equipment. You can rent it to save money.


To apply penoizol, a special installation is required; it can be rented in order to save

To produce penoizol with your own hands at home, you will need to equip the installation. You can arrange it from scrap materials. You will also need a compressor, molds for finished products, And additional equipment for lighting and ventilation. Budget options settings require a combination of:

  • gas-liquid equipment;
  • supply hose;
  • set of taps;
  • plastic barrels;
  • compressor.

Urea resins and catalyst are mixed in the plant. They are placed there using a pump. There is compressed air here. The main attention should be paid to the purchase of a pump, since it plays the role of a key element in production. Errors in dosage are especially important. A vortex or plunger pump is the most profitable and effective option. But in any case, foreign particles should not be allowed to get inside, as this will ruin the whole process.

List of materials and manufacturing technologies

Penoizol is made from foamed urea resin. Its production is characterized by efficiency, affordable price and speed of work. To make it you will need:

  • polymer resin;
  • foaming agent;
  • hardener;
  • specially prepared water.

There are several methods for producing penoizol, according to which sheets and mats are produced. The raw materials are poured directly on the spot where the insulation work is being carried out. If the filling radius of the equipment is large, the material manufacturing process becomes efficient.

You can use gas-liquid units that are easy to use and low in cost. For the production of insulation, installations of the Standard and Pena 2000 types are suitable. The first is characterized by an original dosage system. There is also a second generation system with an increased range.


To produce penoizol you will need a special gas-liquid installation

Comparison with polyurethane foam

The two materials are often compared in terms of financial benefits and technical performance. Safety of use comes first in importance. Manufacturers claim that penoizol is neutral and safe for humans and animals. But at the same time, in a number of states in Canada and America there is a law according to which the use of urea foam for construction is prohibited. It is considered a potential health hazard.

This situation is also observed in some European countries. This is explained by the release of formaldehyde during polymerization liquid foam. You can reduce the likelihood of adverse effects by using a vapor barrier on the inside of the wall.

As for polyurethane foam, there are no bans on it in any country in the world. It has all the necessary quality and safety certificates.

In terms of water absorption, polyurethane foam has minimal indicators, since its structure is porous and closed. It retains heat well and is equipped with protection against corrosion, mold and mildew. The appearance of condensation is excluded here. Despite the positive properties of penoizol, excess moisture can lead to its destruction. This can be avoided by installing moisture insulation.


Heavy humidity may lead to the destruction of penoizol

In terms of strength and physical and mechanical properties, penoizol is also slightly inferior. It is resistant to mechanical stress, but in this indicator it is still ahead of polyurethane foam. In terms of price, urea foam is an order of magnitude cheaper than polyurethane foam.

Use in winter

Work in winter period difficult, since problems are created due to low temperatures air. This factor adversely affects the structural composition of penoizol. Approximately 50% of the resin consists of water. For this reason, the viscosity of the material increases. Despite all these unfavorable aspects, penoizol can be poured under certain conditions. Its components must be stored in a warm room at a temperature of at least +15°C, for example in a garage.

The installation must also be placed in a warm place. You can install the cheapest tourist tent for this. The materials must be rolled up compactly and covered with a layer of polyethylene film, and then install the fan heater. Before starting work, it is necessary to heat the solution to +40°C, and the resin to +20°C. For this, a regular boiler is used.

More details about do-it-yourself penozol:

If all these rules are followed, you can get penoizol that is no different from the material installed under normal conditions. It is unacceptable to keep it at a temperature below +15°C, as it does not dry well. The moisture it contains will freeze. It will fulfill its role as a heat insulator only with the onset of spring. Moisture that does not freeze in the spring will evaporate by itself. Dry foam will remain unchanged.

The building materials market is constantly improving. New technologies are emerging that improve the quality of existing products. At the same time, repair and construction work is carried out faster and cheaper. One of the new materials that is gaining popularity today is penoizol. It has a lot of positive characteristics.

General characteristics

The name of the presented insulation is the name of the brand. There are many other companies that make the same product but under different names. All of them are urea foam.

Among the domestic analogues of penoizol we can name unipor, ecoizol, mettemplast, mipora, teploizol, etc. Foreign names of the presented material are also varied. In the UK, urea foam is called flotofaum, in the Czech Republic - mofotherm, in Switzerland - isoshaum, etc. Moreover, the principle of the presented compositions is the same.

Price

One of the main advantages of the presented insulation is its price. Penoizol costs about 600 rubles/m³. At the same time, the quality of thermal insulation is not inferior to the popular insulation materials existing on the market today.

If we compare penoizol with mineral wool, a product with similar thermal conductivity will cost the consumer 1.5 times more. Moreover, the price of this insulation is 900-1000 rubles/m³.

The price of penoizol is 1.5 times lower than the cost of polystyrene foam. Material with similar thermal conductivity costs 950-1000 rubles/m³. The cost of extruded polystyrene foam is 6.6 times higher than that of penoplex. It is about 4 thousand rubles/m³ (taking into account the thermal conductivity coefficient).

Also, in terms of cost, urea foam is more profitable than basalt slabs, staple fiber and expanded clay. For this reason, many private property owners prefer this type of material.

Compound

Has a lot of advantages. The material is similar in structure to marshmallow. Production does not require large expenses. Therefore, the cost of the product is relatively low. After processing, the output is semi-liquid foam.

After drying, this material is highly elastic. Dents from various impacts on it are quickly straightened out. The material has high thermal insulation characteristics and repels moisture.

When creating penoizol, a certain type of urea resin is used. Acid is added to it. A foaming additive is used in a certain proportion in the composition of the product. A mixture of the listed components is put into the equipment. Compressed air is supplied to it. The resulting substance has a jelly-like consistency. It can be immediately applied to the base of the wall.

Installer reviews

Characteristics of penoizol determine its method of use. After the mass comes out of the unit’s sleeve, it hardens. However, this process occurs gradually. The material sets to the base 10 minutes after application. In this state, penoizol remains soft.

After another 4 hours, the mass hardens. It becomes quite hard. However, penoizol has not yet gained strength. It will take a few more days for the thermal insulation to be ready for subsequent finishing. It gains strength within 3 days. During this time, Penoizol acquires all its positive qualities.

Professional installers claim that thermal insulation of this category is installed much faster than other insulation materials. The surface processing speed will be 4-5 times higher. Moreover, the material is lightweight. It slightly makes the structure heavier.

Thermal conductivity

After hardening it has a mass positive qualities. One of its main advantages is low thermal conductivity. The material allows you to significantly reduce energy costs in winter.

Depending on the structural features, as well as the method of installing penoizol, its layer can be from 5 cm to 1 m. When a layer 10 cm thick is applied to the surface, the room becomes much warmer in winter. The thickness of penoizol is selected individually for each object. In this case, the climatic features of the area and the features of the building itself are taken into account.

Depending on the density and composition of the material, the thermal conductivity coefficient can be 0.031-0.041. This is a good indicator. The presented material is used for both external and internal insulation. When creating a layer of insulation from foam insulation in a room, you don’t have to worry about the appearance of condensation on the walls. At the same time, the finish will last a long time.

Fire resistance

after application to various surfaces, it gains its basic qualities within 3 days. In addition to low thermal conductivity, penoizol, after hardening, demonstrates high fire resistance. This sets it apart from many insulation materials.

Even at very high temperatures, the presented material does not ignite or even melt. At the same time, it does not emit smoke or substances hazardous to human health. This is an environmentally friendly material. Due to its fire resistance, penoizol can be used on a wide variety of private and industrial facilities. It is operated in a thermal range from -60 to +80 ºС.

To understand how penoizol behaves at elevated temperatures, you should consider the following situation. If the ambient temperature rises so much that the metal begins to melt, the insulation presented will simply gradually evaporate. At the same time, hazardous chemicals will not be released into the air. During a fire, smoke from penoizol is released 10 times less than from expanded polystyrene.

Resistance to various influences

which forms insulating layer on various surfaces indoors and outdoors, it is highly resistant to various biological and chemical influences. The material is not subject to the destructive influence of various solvents and active substances.

The presented insulation does not harbor various insects and mice do not gnaw through it. The fungus is also unable to reproduce on its surface. These qualities allow you to create a healthy microclimate indoors.

One of the advantages of the material is its ability to pass air. This allows you to regulate the humidity level in the room. The owners of such a house note that the indoor microclimate is healthy and there is no dampness. The inside of the building is dry and warm. Various pathogens practically do not reproduce in such an environment.

Moisture absorption

Today, many installers use penoizol in cylinders. This insulation is very easy to use. At the same time, thermal insulation has a high level of moisture absorption. He's also good at giving it away environment. This allows you to maintain an optimal level of air humidity.

If penoizol gets wet, it dries quickly. At the same time, its original characteristics remain unchanged. This process does not affect the properties of the insulation in any way. It retains heat well in the room and does not ignite. The walls will not be damp. However, experienced installers recommend not to neglect high-quality ventilation.

The hygroscopicity of the presented insulation allows walls and finishing materials to deteriorate much more slowly. In this case, the insulation layer can absorb from 10 to 20% of moisture from the environment per day.

Strength and Durability

Characterized by high softness. Once on the base, it adheres well to any surface. At the same time, the insulating layer effectively covers all irregularities. No voids or gaps appear under the thermal insulation.

Penoizol gradually gains the strength specified by the manufacturer. However, it is not very tough. When bent, the material breaks. When you press on the material, it quickly expands. The elasticity of such insulation remains high. But when bent, the insulation does not exhibit high strength.

When conducting research on the characteristics of penoizol, it was found that it is capable of operating at correct installation 30-50 years. These data are confirmed laboratory research. The presented material has been used in construction relatively recently. However, according to its main operational characteristics it becomes clear that this is a durable insulation.

Negative reviews

IN various sources you can find many positive and negative reviews about penoizol. Who insulated their home with this material, in most cases they are satisfied with the result. However, there are also negative reviews.

After pouring penoizol, its shrinkage ranges from 0.1 to 5%. This is an insignificant indicator. However, if there is insufficient vocational training master or when not used quality material this figure may increase.

There are also reviews about the unpleasant odor of the insulation, which appears during the drying process. This phenomenon occurs only in products low quality. Do not contact dubious installation organizations. When penoizol dries, a small amount of formaldehyde may be released. However, its quantity is insignificant. It is enough to leave the windows in the room open to quickly get rid of the unpleasant odor when the insulation hardens.

Positive Feedback

Minor disadvantages of penoizol cannot affect its relevance and ever-growing popularity. Many positive feedback those who mounted the presented material at home, talking about high quality insulation.

When used, the room becomes much warmer. Energy bills decrease in winter. At the same time, the room becomes warm and the humidity level is maintained at a level optimal for human health.

Installation is very fast. Moreover, the cost of such finishing will be several times less than when using other types of insulation.

To perform quality insulation with penoizol, you need to contact only verified installation organizations. They provide a guarantee on their work. Materials used for insulation must have appropriate quality certificates.

Ready penoizol should not settle. He has white. After drying, the material has a cellular structure. There should be no air bubbles in it.

Reviews about the use of urea foam insulation will help you draw conclusions about penoizole. Who insulated their home using the presented material in most cases they are satisfied with the result.


The mid-90s of the last century was a turning point for the building materials market. Practical and inexpensive types thermal insulation, for example, mineral wool, glass wool, cellulose-based insulation. These materials attract the attention of buyers with their affordable price and relatively good characteristics.

However, there are also significant shortcomings. In particular, these are quite large materials, and the thickness of the insulation board “conceals” interior space premises. In addition, such thermal insulation can dry out and become painted, which invariably leads to heat loss. Of course, mineral wool is still considered one of the popular thermal insulation materials.

However, this is not caused high efficiency, but at an affordable price. If there is a need for really high-quality thermal insulation of premises, penoizol is used during construction. This is a liquid insulation material that is rapidly gaining popularity in our country.

What kind of thermal insulation material is this?

Let's start with definitions. The name "Penoizol" is a trademark of insulation created on the basis of urea resins. The material is in high demand, so it has become a household name, combining the following names:

    "Teploizol"

    "Mipora"

    "Unipor"

    "Mettemplast"

However, among professional builders, insulation is better known as liquid or poured foam.

By appearance, thermal insulation resembles marshmallows, which, after hardening, turns into an elastic mass that is guaranteed to fill all voids.

The composition of the insulation includes the following components:

    Urea resin

    Phosphoric acid

    Foaming additives

The ingredients are mixed in certain proportions and pumped into special cylinders where the mixture is under pressure.

Technical characteristics of urea-formaldehyde foam (UFP)

It is believed that in terms of stated performance qualities, penoizol is superior to any insulation available on the market. domestic market. The main characteristics of thermal insulation look like this:

    Thermal efficiency. The thermal conductivity of insulation varies within 0.031-0.041 W/m on the Kelvin scale. It is enough to pour a layer of liquid foam into 10 cm to provide interior spaces reliable insulation.

    Soundproofing. Penoizol absorbs up to 65% street noise, which is considered a very good indicator.

    Fire safety. The material is not flammable and does not support combustion. However, when exposed to high temperatures, the insulation will simply evaporate without releasing toxic substances into the air.

    Dependence on chemical and biological factors. The insulation is neutral to any aggressive environment. In addition, the insulation is of no interest to rodents and is resistant to pathogenic microflora: fungus, mold.

    Moisture resistance. The material absorbs moisture well, but subsequently evaporates it without losing its original properties. Given this feature, it is recommended to equip ventilation gaps to prevent mold from appearing on the walls.

    Strength. Indicators of linear compression of insulation are 0.07-0.5 kg/cm2. Accordingly, the material holds its shape well and quickly restores its structure.

Manufacturers assure that thermal insulation can last 30-50 years without loss of quality. However, insulation appeared on the market relatively recently, so there is no evidence of such an impressive service life yet.

Advantages and disadvantages of hardened thermofoam

The popularity of penoizol did not arise from empty space. Among the undeniable advantages of insulation are the following features:

    High technical properties - even a layer of insulation in 45 mm, can prevent heat loss.

    The elastic structure allows it to be restored to its original state even after prolonged compression.

    Neutrality to any external influences- sudden temperature changes do not affect the quality of the insulation.

    Excellent adhesion- thanks to its liquid structure, the thermal insulation adheres well to any surface and fills all voids.

    Multifunctionality- insulation is suitable for any structure, regardless of geometric shape.

    Vapor permeability- when using penoizol, condensation does not form on the walls, which is very useful for wooden structures.

In addition, liquid foam does not form cold bridges.

Of course, it wasn't without its drawbacks. Weaknesses insulation are considered:

    Shrinkage- after pouring, the volume of material may be reduced by 0.1-5%.

    Moisture absorption- if we are talking about foundation insulation, this parameter can be regarded as a disadvantage.

    Dependence on temperature conditions - you can work with penoizol only at air temperatures above +5 degrees.

    Low tensile strength- despite the elastic structure, the insulation is easily torn and pierced, which violates the thermal insulation performance.

The disadvantages include high cost. It is curious, but the price of insulation does not exceed the cost of mineral wool and other thermal insulation materials. However, pouring liquid foam requires special equipment, which private developers do not have.

Therefore, you have to rent equipment or hire a team of construction workers, which adds to the overall cost of the work.

Independent reviews from construction forums

To understand the real effectiveness of insulation, you should not unconditionally trust the words of sellers and manufacturers. It will be much more effective to turn to reviews real people, who have already used the subject of our conversation for insulation. Let us immediately note that opinions on the properties of liquid thermal insulation are divided.

Not bad, but there was a small nuance. Alexander (www.forumhouse.ru)

Penoizol is great alternative any kind modern insulation materials. The price is quite reasonable, the mice will not be carried away, the declared characteristics are at high level. However, during practical use a small drawback emerged: when insulating wooden walls there were empty areas left.

Recommended by friends. The house has a comfortable microclimate. Ildar (mastergrad.com)

We decided to insulate the walls with foam insulation around 5 years back: outer wall from block and brick. Between the masonry remains 6-7 centimeters free space. Glass wool and mineral wool did not give the expected result: the wall began to mold, the rooms were quite cool.

Friends recommended penoizol. As the crew worked, one could hear and see the insulation filling the space between the walls, emerging from the cracks. Now the house maintains a comfortable microclimate at any time of the year.

No complaints, but problems arose during the filling process. Mikhail (forumnov.com)

It is clear that seamless insulation has undeniable advantages. There are no complaints about the quality of insulation, however, a network connection is required for the equipment to operate 380 V. I did not have such an opportunity, which caused some difficulties during the pouring process.

I really don't like the toxic smell. Konstantin (forum.vashdom.ru)

After pouring, penoizol noticeably decreased in volume, which already reduces the quality of thermal insulation. In addition, the material has an unpleasant and clearly toxic odor. They said that the composition included formaldehyde, the use of which has long been abandoned in European countries. I recently insulated the house, so I can’t say anything about the properties of the material, however, doubts about the correctness of the choice are already tormenting me.

The price of the work is steep. Eduard (www.forumhouse.ru)

Personally, I am satisfied that penoizol will not be chewed by mice, the insulation accurately fills any gaps, and provides reliable heat and sound insulation. I didn't like the fragility of the material and its susceptibility to deformation. Yes and total price the work is a bit of a pain.

In order for penoizol to fully live up to the hopes placed on it, it is necessary to strictly adhere to the pouring technology. If this is your first time encountering liquid thermal insulation, it is better to immediately contact specialists who can do the job efficiently.

Wall insulation is carried out according to the following scheme:

    IN wall structures holes are drilled into which penoizol is pumped through the filling hoses.

    Install a protective facade made of metal profiles, leaving a gap between the wall and the metal 5-10 cm.

    Fill the free space with insulation.

    Waiting 4 hours To allow the material to set, cut off the excess insulation and begin finishing.

Roof insulation:

    The surface intended for insulation is covered with a film that should extend onto the walls of the attic by 10-15 cm.

    Fix the membrane with staples.

    The slats are stuffed on top of the film.

    The space between the slats is filled with insulation.

    Waiting 15-20 minutes To make the insulation viscous, level the surface.

    Through 4 hours you can begin further work.

Floor insulation:

    Wooden sheathing is being installed.

    All sections are filled with insulation.

    When the material hardens, a plastic film is placed on top.

    Execute finishing: lay boards or pour concrete.

In principle, working with penoizol is practically no different from installing other types of insulation.

Consumption rates for insulating material per 1m2

When planning a construction budget, you need to accurately determine the amount of material. To determine the amount of liquid insulation that will be required to insulate the entire building, you need to know the consumption rates of penoizol per square meter.

According to manufacturers, the consumption of liquid foam per 1m2 varies within 1-1.3 l.

To calculate required quantity material, you need to multiply the length and width of the wall by the consumption rates stated by the manufacturer. For example: 7*3.2*1.3=29.12 l. In this case, the final amount of thermal insulation must be taken with a small margin, taking into account unforeseen situations.

Manufacturers of urea foam plastic in the Russian Federation

Many companies in Russia and Europe are engaged in the production of penoizol. However, to purchase quality material, you need to take a responsible approach to choosing a manufacturer. Therefore, we advise you to pay attention to the products of such companies:

    "New construction technologies» . The company was founded in 1990, specializes in production heat and waterproofing, fiberglass, fiber-reinforced concrete. Today, this is one of the main suppliers of penoizol on the Russian market. By the way, the rights to use this trademark belong to this company.

    "Varmal LTD". This is a British company engaged in the production of liquid insulation flotofaum - the name of penoizol.

    LLC "Uveis" Russian company, located in the city of Orenburg. The manufacturer has been working on the market for a long time, so it carefully monitors the quality of its products.

In addition, customers respond positively to the products ProTeplo LLC, Penoizol-Omsk LLC, Murmansk Universal Plant CJSC.
