Insulation of walls with foam insulation: material features and step by step execution. Insulation with foam insulation: application, feedback.

Building a house is an important process in which you need to take into account a lot of nuances. Every year, more and more demands are made for the erection of housing, especially in terms of achieving energy saving and saving fuel. Modern materials can significantly help in this, however, they should be chosen correctly. For example, recently such material as penoizol reviews gets positive and is worthy of competition with the more popular ecowool and styrofoam. What are its features? And for what in general it is necessary to warm your house?

How to insulate the house?

Let's start with the answer to the last question. In any house or apartment, especially in those that were built in the Soviet times, too much heat loss - they can reach and 40%. In the end, a lot of money has to be spent on heating our homes, because the heat leaves our homes through external walls, floors, windows, doors, and also the roof. Modern methods of insulation, for example, insulation with foam, can solve a number of important issues:

1. The optimum indoor temperature will be maintained throughout the year.
2. The walls will be protected from humidity, accumulation of condensate, and therefore will be reliably protected from fungus and mold.
3. The acoustic properties of the structure improve.
4. The noise insulation level in the room will be higher.
5. The hygienic state of the room will become much better.
6. Will be below the expenditure on energy.
7. The erected house will be more durable and economical in operation.

Of course, even the insulation of houses with foam insulation will not protect the room from heat losses completely, but at least they will be minimized. In addition, it is important that the work on the installation of insulation material is carried out competently and professionally with the observance of technology.

Penoizol: what are the features?

Typically, as a heater, eco-wool, polystyrene is most often used, but today penoizol is also becoming quite popular. He has many advantages, each of which plays a role in the formation of such a good opinion about the material. Firstly, penoizol is completely uninteresting to rodents and microorganisms, so you can not worry that the walls will gradually be eaten from inside. It is noteworthy that if the material is mechanically affected, it will turn into dust. The second important point - penoizol reviews gets positive in view of the breathing structure and good thermal insulation properties. Due to the presence of capillary moisture transfer in the material, it can be safely used in wooden construction, while the appearance of mold is excluded. All the excess moisture will be eliminated capillary insulation. The third positive point - in comparison with eco-wool and glass wool, the material described by us is hermetically sealed, it literally fills all the pores and details in its path.

Porous structure is the key to reliability

The carried out researches have allowed to bring together all features, which has penoisol. Its characteristics are as follows:

1. The coefficient of resistance is higher by 40% compared to mineral wool and cellulose heaters, which means that the level of heat losses will be minimal.
2. Penoizol is not afraid of moisture, which can destroy the wood and lead to defects in the walls or roof. The material has a porous structure, so all the accumulated moisture instantly dries up, which means that there is no reason for experiencing.
3. The average heater is sagging for 10-12 years, respectively, there may be cracks in the walls or floor. If insulation is chosen penoizolom, then this can be avoided, because it fills all pores, and the period of its operation can reach 70-80 years.

Where is penoizol used?

A modern homeowner always faces a choice of quality and reliable materials, especially when it comes to thermal insulation. Penoizol reviews got positive just because it represents a unique combination of price and quality. In addition, this material can be used to insulate both the floor and the roof both in new buildings and in houses already in use. Penoizol is a carbamide foam, which has a cellular structure. Due to its excellent physicochemical characteristics, the scope of the material is quite wide. The material is available in the form of a liquid foam, so it can easily fill all the cavities in which it quickly solidifies. For insulation of the walls, you can choose and sheet foam isole.

Features insulation of a wooden house

Wooden housing construction is popular because the walls in such buildings "breathe". But this same characteristic makes the process of warming quite difficult. For example, to insulate the facade of a house of a chopped house is almost impossible, but in the bar version of penoizol reviews got good. Perhaps the use of this material and for the panel house, however, in such cases, not liquid foam is used, but a sheet that is pre-mounted on the prepared profile.

Warming of walls: what to consider?

Insulation foam for walls - the most optimal solution, because it:

• does not burn;
• resistant to mold, fungus, rodents;
• vapor-permeable, that is, excess moisture comes out;
• durable (the service life is at least 50-70 years).

Due to its excellent thermal insulation properties, it is not only convenient but also advantageous to insulate the house with foam foam because it is easy to install and keeps the heat well. You can stack penoizol in two ways - in the form of slabs or thick foam. It is important that the resistance to vapor permeation of the inner layer is higher than the resistance of the outer walls.

Secondly, do not choose as a vapor barrier material film, foil, roofing material, as there will be no air interlayer between the walls of the building and the outer territory. To increase the efficiency of using this insulation, it is best to combine it with wood, concrete, brick or gypsum. When laying slabs, avoid the gap between them and the wall.

Stages of wall mounting

The process of thermal insulation of walls will consist of several stages:

1. Mounting sheet insulation in the masonry when building walls.
2. Sheathing with sheet material of external walls, after which their lining is performed.
3. Laying sheet insulation on internal walls under the finishing material.
4. Backfilling the foam foam foam into the voids of the walls, as well as under the drywall.

Attention to the ceiling and the facade

Penoizol is well suited for the insulation of the ceiling. True, experts recommend using it in premises with a large area, since the presence and work of professional masters will be required. is simpler. Thanks to the fact that the penoizol characteristics are excellent, it can become a reliable protection of the walls. The essence of the facade insulation is as follows. First, a supporting structure is mounted on the wall, for example, from a galvanized profile. Magnesite slabs are screwed onto it, in which holes are made - it is here that penoizol is poured. After its polymerization and solidification, the walls can be painted or clad with decorative materials. For the facade, this solution is quite convenient and functional, since penoizol in combination with magnesite slabs has good vapor permeability. The walls will "breathe", supporting a favorable microclimate in the room. In addition, the facade will meet all requirements for fire safety and sound insulation.

Floor and roof

Penoizol is excellent for insulating floors and roofing, but it is important to not forget about the ventilation system. The process of installation includes several stages:

1. Installation of the material under the floor (under the concrete screed or between the lags).
2. Laying sheet insulation in the attic, attic, as well as technical floors.
3. Installation of foam in the suspended ceiling.
4. Warming of the roofing system.
5. Filling foam foam in the floor, loft.

Depending on the design features of a particular housing unit, foam foam can also be used along with the sheet material. This type of foam can be poured immediately on the building site. The effectiveness of this method is that the liquid material does not increase in volume and slightly "shrinks". Accordingly, to avoid the appearance of cracks in the walls, it is important to follow the technology of its laying. Liquid penoizol should be used at an air temperature of at least +1 degree. Such a composition is quite possible to insulate and already operating buildings, filling the cavities and cavities in structures, which at the same time will remain strong.

How is it produced?

In modern construction, a heating material such as foam isole is in high demand. Its production is carried out on the basis of a specially prepared foam-forming composition with the addition of various components. Due to them, the physical and mechanical properties of the material change, and its performance characteristics are also improved. A foamed mass appears from the special foam-forming sleeve, from which then the heater will turn out. Within 15 minutes it hardens - this is the first stage. The next stage begins approximately in 3-4 hours.

Penoiziol contains about 90% of the gas sphere, but the following components are supposed to be used as raw materials:

• orthophosphoric acid;
• foaming agent;
• resins;
• carbamate;
• water.

Features of the equipment

Equipment for the production of foam is a number of units that are inexpensive. First, it includes a gas-liquid installation, which directly produces penoizol. It consists of a SCU, a supply hose, a set of cranes for connecting containers, as well as various application documentation. Due to the compactness, the unit can be easily transported. Secondly, you need a compressor that produces compressed air. Thirdly, to produce penoizol will require capacity - ideally they should be three. In this capacity, you can use conventional barrels of polyethylene or iron with a volume of 30-200 liters. For the convenience of transportation of the installation on the construction site, it is desirable to purchase a cart with GZHU. Thus, in order to create a material such as penoizol, the installation must be assembled in its entirety.

How and where to apply penoizol?

Carbamide foam is used quite widely, while in different countries it is produced under different brands and names. It is thanks to the processability of the material and its excellent performance characteristics that penoizol is so popular as in most developed countries it is the casting of a souffle-shaped foam isole in the cavity. However, this material can be used in non-standard ways. For example, in the Czech Republic, reinforced concrete panels are used in three layers, one of which is a 50 mm foam foam. In the US, concrete blocks are used for construction, in which the cavities are filled with foam insulation.

In Poland and Hungary, the use of this material is due to its resistance to burning, so in these countries they are filled with garbage dumps - a kind of coating protects waste from ignition.

As a thermal insulation material, porous foam is used in the Netherlands, Poland, France, and also in the Baltic States. When constructing houses between the walls, a gap of 40-60 mm is traditionally left, which is subsequently filled with a foam-insulated mass.

Why is penoizole so popular?

In the search for quality insulating materials, many builders are looking for something that would not only be reliable, but also economical in terms of cost. Typically, the use of penoizol is due to the fact that they are well warmed buildings with a wall thickness of approximately 10-20 mm, since this will reduce the cost of heating the house several times. And the cost of the insulation work will be repaid already during the first operation of the residential facility. Using a carbamide foam to decorate the internal openings of the walls or warm the facade of the house, you can effectively protect it even in severe frosts. An important role is played by the cellular structure, which perfectly protects the interior from noise penetration.

Few know about the existence of such a remarkable insulation material, as urea-formaldehyde foam (CFP). It is a unique insulation and sound absorber for walls, ceilings and roofs for residential or industrial buildings. It is prepared by mixing several components in a special installation, after which a fill is made into the space between the inner insert and the lining. The corresponding liquid mass can be made on the construction site with your own hands. If the funds allow, it is easier to buy it, although the price will be slightly higher.

This insulation belongs to the class of foam plastic is also known as Penoizol, Mipora, Unipor or Mettemplast. What is so unusual about penoizol? Penoizol is a liquid heat insulator that is poured under a vapor-conducting membrane into a pre-prepared cavity between the wall and the hanging facade.

Figure number 1. Warming of the facade with foam insulation

Insulation with foam is considered an economical way to improve the comfort of the home, which is the reason for its popularity. In liquid form, it looks like a souffle, which almost instantly hardens when in contact with air. Due to its fluidity, the component can fall into all hidden cavities, providing high-quality and reliable protection against cold.

If there is a certain desire, knowledge and equipment, it is possible to organize without problems the production of penoizol by oneself. Even if there is no special equipment and installation - the corresponding units can be built independently. The presented insulation of walls, ceilings and partitions is not demanding in operation, has a minimum weight and is able to perform its work adequately in all weather conditions.

The advantages of the insulator include the following:

• 1. According to the manufacturers, the liquid or sheet foam isolator is able to perform its functions for at least 75 years, preserving its properties.
• 2. Favorable price, which is at a level of 790 rubles per cube, which will be enough to insulate the wall area of ​​up to 20m2.
• 3. When operating from a heater, no harmful resins or other undesirable components are released, which makes it possible to call the composition environmentally safe.
• 4. The ability to prepare and apply on the walls with their own hands (observing the technology, having some experience and knowledge).
• 5. Full drying of the material 6..8 hours, while foam solidification occurs after 15 minutes of contact with air.
• 6. Treatment of the composition of walls, ceiling and floor allows you to significantly reduce the arrival of noise in the room.
• 7. In ready-made form it is not subject to burning, under the influence of open fire it will be slightly charred, and at the same time do not form dangerous and toxic substances. Correct laying of the material in the wall or overlapping, the implementation of the application technology will ultimately provide a safe and reliable construction structure.

Picture number 2. Comparison of the characteristics of different heaters

Among the main disadvantages of penoizol can be noted:

• 1. Its ability to shrink after filling. In this regard, industrial foam is preferable.
• 2. The presence of a sufficiently acute and unpleasant odor, which is not characteristic of other quality materials. When buying or preparing material for this should pay special attention.
• 3. Possessing increased hygroscopicity, which allows it to easily absorb condensate, in fact, as well as to remove moisture. Directly, its laying, as in the version with mineral wool, is performed with a decoupling on the bottom line when processing walls or socle rooms of the house, while not wetting the material.

Technical features

Below are the main values ​​of technical parameters:

• 1. Moisture absorption of 10.20%.
• 2. Thermal conductivity not more than 0.047W / mChK.
• 3. The temperature range of use is -50 .. + 1200 degrees.
• 4. Density in the free state 8..28kg / m3, in the bent state 0.10..0.25kg / cm2, in the compressed state 0.07..0.50kg / cm2.
• 5. High processability (an average of a day can be filled to 50m3).

One of the most interesting indicators of the component is vapor permeability. Comparing it with other popular liquid compounds for insulation of walls and roof, with which fill any voids and gaps, only it is able to maintain the optimum value of the level of vapor permeability. This allows you to easily remove excess moisture from building structures.

Figure number 3. Injection of foam insulation in the cavity of the wall

At the same time, this feature, as well as low compressive strength, does not allow the insulation of houses with foam insulation, namely their foundation and concrete parts.

Among other things, penoizol is safe in fire prevention. A heat-insulator belongs to the group of flammability not lower than G-2. It does not support combustion, but gradually loses mass due to evaporation. At the same time, critical substances are not released into the atmosphere.

Very often when laying the liquid composition on the walls, reinforcement is also carried out with the help of polymer fibers. This approach guarantees increased strength characteristics of the material, in particular, on the break and the absence of its subsidence. Usually, similar work is done when applying a heat-insulating layer on walls of 70..80 mm or more so that they do not crack and do not crumble during prolonged use.

Figure number 4. Warming of the roof space with foam insulation

Production of foam isole

By itself, this composition for the insulation of walls is quite inexpensive, but even more profitable may seem the production of penoizol with their own hands. At its cost, it is ten times preferable to the use of fiberglass or mineral wool. The insulation is universal, and it is suitable for the treatment of a wide variety of surfaces, be it roof, communications, walls, ceiling, etc.

To prepare a liquid material you will need to purchase equipment for the production of foam insulation. Its price can reach 800. 1200 dollars, which is quite a bit for capital construction. In addition, it is recommended to purchase a special design in which there is a gas-liquid installation, a transport hose and a set of cranes. It is necessary for the supply of finished material. Due to the compact dimensions, the unit easily moves to the next place of work.

Figure number 5. Equipment for the preparation of foam insulation

In addition, for the preparation of foam is required a compressor, through which compressed air will be supplied, as well as plastic or metal tanks for 30..200 liters. The main components of the material are only 10%, and this is water, carbamide, orthophosphoric acid, foaming agent, resin, and the rest is taken by the air mass.

In its original phase, the insulator has the consistency of a liquid thick thick foam, so that it easily fills the hollow air layers in the walls. No problem and pouring it into the floor or ceiling. As it dries, the material gradually solidifies and turns into a continuous polymer with a finely porous internal structure. Due to its ease and accessibility gets the best reviews.

How to prepare penoizol?

Having studied the relevant literature, drawings and documentation it will be possible to easily manufacture the simplest installation for the preparation of liquid foam insulation by one's own hands. All the necessary details and elements can be purchased at any construction shop.

Video number 1. Thermal insulation of the building with foam insulation

The process for the production of foam isoze includes foaming the solution with a catalyst and mixing the resulting mixture with a formaldehyde-urea resin. Through the operation of the hydraulic pump, the constituents enter the installation where the solution is foaming. The necessary technologies, drawings and other materials are generally available on specialized resources.

Conclusion

In conclusion, it must be said that all user feedback and the given terms of use of the material are only indicative, since in practice all these parameters, for obvious reasons, have not yet been confirmed. As of today, certain statistics and recommendations for use, proper application of the material to the walls and other uses, unfortunately not. That is why, when acquiring a plant, equipment, a ready component and planning its laying, it is worthwhile to think it over carefully.

Video number 2. Poor insulation by foam insulation

For low-rise residential, industrial and public buildings, nowadays, foam insulation is often and successfully used. In addition, it serves not only as a thermal insulator - due to its structure it excellently absorbs sound waves, therefore it is also used for partitions.

In construction, the material can also be found in hangars, covered areas, boxes and garages, in addition, the product is used for walls, roofs and floors.

About insulation and installation

What is penoizol

• Penoizolom called karamidno-formaldehyde foam (KPP), which is also under the trademarks of mipora, unipora, mettaplasta, aminoterma, myphoterm or isoleja (there are other names). Combined with low thermal conductivity, the material also has a low bulk density and in many ways is identical to the usual for all. After drying, this similarity is also noticeable in the visual sense - the white, fine-mesh material is odorless, elastic when touched.

After drying, this similarity is also noticeable in the visual sense - the white, fine-mesh material is odorless, elastic when touched.

• GOST 16381-77 relates carbomide-formaldehyde foam to organic cellular materials and has a group of low-density ONP - from 8 to 28 kg / m 3. The claimed heat conductivity of the KPF has a coefficient from 0.012 to 0.047W / m 2 K, and it also has high fire resistance and ease of mechanical processing (installation). The price of the material is relatively low.
• One of the advantages of liquid foam plastic can be called the possibility of pouring material directly on the construction site, which significantly saves its consumption. Unlike the construction installation foam KPP does not expand during installation, but on the contrary, it even slightly shrinks. The water absorption of the material is no more than 0.3% of the total volume, but this is the latest development, since earlier this figure could reach 18% -20%.

Council. When pouring insulating foam on the construction site, the minimum air temperature should be at least 5 ° C. Otherwise, after drying, cracks in the insulation layer may occur.

Material Safety

• Manufacturers of carbamide-formaldehyde foam in Russia assure the fullest ecological safety of the material and confirm it with licenses and certificates. But, for example, in the UK, the use of CFPs is permitted in accordance with the requirements for toxic elements. Perhaps this is due to the increased content of formaldehyde, and this option is possible in poor-quality production, which is unacceptable (read - it is impossible) with the latest technology.
• In addition, the risk associated with the release of formaldehyde into the environment, that is, in the room, is reduced not by waterproofing and vapor-conducting films used in the construction of buildings. Nevertheless, given the possibility of some companies being dishonorable, one should be careful when choosing them and pay attention to their reputation.

Foam insulation installation technology

• In order to make insulation of houses with foam isolators, a foam generator is needed, which actually produces carbomide-formaldehyde foam and immediately, with the same apparatus, it is poured or foamed. For example, consider the installation of "ISOL norm", which recently is the leader in sales in the Russian Federation.
• The "ISOL Norm" setting allows the components to be dosed electronically, and in the same electronic mode, the infeed is carried out when pouring the eco-isol on the object. In cases where there are voltage drops, the device automatically stabilizes the supply of components, as a result of which the density of the filled foam and the capacity of the unit remain unchanged. For dosing all components, pumps with a volumetric collector drive are used.
• In the configuration of the device there is a specially designed filling sleeve with two outlet valves, that is, the possibility of alternating filling is given. With an additional set of hoses, it is possible to raise the filler foam to a height of up to 50 m. The capacity of the unit operating from the 220V network is from 250 to 350 liters per minute.
• The setting of the "ISOL norm" is carried out by means of a knob on the control panel (density of the filler foam). Also, full wireless radio control is possible, which allows one person to cope with the process. Dimensions of the device 480x440x290 mm with a mass of 25 kg.
• Due to the decrease in the amount of water per 1m 3, the "ISOL norm" (three times less than usual) produces a high-quality EKOIZOL foam foam. The porous structure of such a material is uniform for any density. Also "ISOL norm" is able to produce penoizol (read - eco-isole) with a density of 5 kg / m 3, which was not possible to achieve earlier.

• The technology of working with foam isolates allows using it practically in any desired place, that is, it can be a pouring between the inner fence and the slate; filling of the sinus between the inner and outer wall, pouring between the main wall and gypsum plasterboard; pouring under siding, PVC / MDF panels and wooden floors. Also, this method can produce a loggia or balcony insulation with your own hands.

Council. If you want to insulate the already constructed construction (walls, floor, ceiling) and there is a gap there, then you do not have to disassemble it to create access. It is enough just to drill holes in the holes in some places along the diameter of the hose and to pour penoizol through them.

• In the wall, holes are made, as seen in the photo above in different places, which should be slightly more than the thickness of the hose (for convenience). Considering the fact that the density of the injected material is extremely low, it can without any doubt be used even in dilapidated structures - unlike penoizol it does not expand when hardening and the structure does not break.

Penoizol does not expand when it solidifies and the structure does not spread.

• Through the holes drilled in the stitches in the staggered order, the filling of the KPF begins, and this is done from the bottom up. The material evenly fills the cavity and begins to flow through the adjacent holes - at this time, seal them with plugs of wood, until the mixture dries. The poured mass has no seams and joints, which ensures the density of thermal insulation, moreover, such material has no limitations in terms of operation.

After the filling of the insulation is completed, you can seal all the holes or close the penoizol with any lining. The video in this article will help you to further understand this issue, because all the same visual aid is much more effective than written instruction.

Penoizol not so long ago appeared on the construction market of thermal insulation materials. However, due to its properties and installation method, it earned considerable confidence both among large construction companies and among private organizations engaged in the erection of residential buildings. Thermal insulation of the house with foam isolator differs significantly from the use of the usual foam plastic or mineral wool and is not inferior to them in terms of characteristics, which immediately won a part of the market. Now we are considering strategies for deeper penetration of penoizol wherever maximum thermal insulation is required, and there are no significant loads.

Penoizol refers to liquid foams. Ready mix is ​​obtained directly on the construction site before filling the prepared niches and voids. Liquid and loose heat insulators are gaining popularity both in frame construction, and for the insulation of buildings already in operation. In the presence of an air gap between the bearing wall and the lining, liquid insulators can create an inseparable and reliable layer of insulation without the need to disassemble part of the structure or to expose the structure.

The main component is urea-formaldehyde, an organic resin that can quickly polymerize in contact with the hardener, while having a low surface tension. For the manufacture of insulating material, a soap foam mixed with water with the addition of a hardener for resin is taken as a basis. Immediately prior to use, urea-formaldehyde resin is added in a strictly prescribed proportion to obtain the required density and strength.

After leaving the hose for material distribution, it takes 10-15 minutes for the primary polymerization and curing of the resin. At the same time, volume changes are not observed, as, for example, in the case of polyurethane foam (mounting foam). Ready insulation is obtained after the water is completely evaporated, and the process of curing the resin will end. This takes from 2 to 5 days depending on the conditions on the construction site.

The conditions under which penoizole is applied and dried out largely characterize the properties of the result. For increased strength and reliability, it is advised to limit the rate of evaporation of moisture and thereby allow the resin to be effectively mixed with the hardener.

If you look at penoizol with an increase, you will see its structure. These are open cells, the size of which is measured by micrometers. The resin freezes mainly only along the contact lines of the foam bubbles and forms only the cell skeleton. This largely determines the property of penoizol. It is equally hygroscopic, vapor permeable and resilient.

Specifications

The material does not support burning, which makes it much more attractive than expanded polystyrene for insulation of buildings, especially with the use of wooden structures.

Permeability can be called the main advantage of penoizol. In comparison with other liquid heaters, which can fill gaps and voids only it is actually able to maintain a normal level of vapor permeability to remove excess liquid from the wall thickness or overlap. However, this circumstance, along with a low compressive strength, does not allow the use of a heater to protect the basement or to mount a layer of insulation to a concrete screed.

In addition to penoizolu is applied as necessary micro-reconciliation. Polymer fiber is added, which can strengthen the material and prevent its subsidence, increase the tensile strength. It is necessary in those cases when it is important to avoid any shrinkage or to secure a layer of warmth more than 6-7 cm from the spillage with time.

Technology of insulation of walls and floors

Penoizolom allowed external insulation of the walls of buildings for any purpose, pitched roofs along the internal surface of ramps and floors that separate the attic from the residential area. Excellent for restoration work, warming of existing buildings with a three-layer structure of walls and the presence of an air gap.

For the preparation and application of foam is used a specialized equipment capable of mixing components in the required proportion and by means of the pressure created by the compressor station to be delivered via a flexible pipeline to the destination. Prepare by hand and apply material will not work, because the quality of the result directly depends on the accuracy of the machine performance of all stages of preparation of components.

Equipment

Stations for the preparation and transportation of penoizol include:

• two containers for soap solution with hardener and resin;
• compressor;
• pumps with a dispenser;
• control and indication unit;
• transport pipeline.

The stations are specially designed for the use of penoizol and similar multicomponent building mixtures. Controls the consumption of materials, pressure, mixing method and delivery head. The quality of the heat insulator at the outlet and, most importantly, the repeatability depends, in part, on the experience of the operator.

High-pressure, closed method

• Warming of three-layered walls.
• Warming of plates and other multi-layer reinforced concrete structures with voids.

Used to fill the gap between the main wall and facing of brick, reinforced concrete slabs, strong corrugated board. Especially popular is the insulation of buildings already in use.

It is enough to drill in a layer of facing or to drill in the facade holes with a diameter of 25-30 mm with a certain step over the entire area of ​​the insulated wall. Under high pressure, up to 5 atmospheres, penoizol is blown alternately through all the prepared holes. It easily rises and spreads to the sides, filling the entire volume provided

Under pressure, the material is evenly distributed in the space between the walls. It has a weak adhesion with bricks and concrete, which allows evenly filling the entire cavity. By the way penoizol leaves from neighboring holes, follow the filling and the release of excess air.

This method is suitable for filling cavities over 5 cm, formed by strong materials, capable of withstanding high pressure.

Low pressure, open insulation

Warming:

• pitched roofs, attics;
• overlapping;
• facades;
• walls.

In a low-pressure method, penoizol is simply poured gradually into a niche where it is possible to control the uniform filling.

To insulate the roof, it is sufficient to form niches on the lags, limited by waterproofing from above and a vapor barrier membrane from below and filling them with foam insulation. Even with a low material density of only 10-25 kg / m3, it is necessary to use fabric-reinforced materials with high tensile strength.

As the house is erected, when the main wall and brick lining are being formed simultaneously or the elements of the frame building are mounted, the foam is evenly distributed in the niche. The process is divided into several stages, so that at the same time the optimal volume of one refueling of equipment is used up in one run.

Warming of ventilated facades is carried out in the same way as pitched roofs. First, using a vapor barrier and a vapor permeable membrane, niches are formed and then filled with a solution of penoizol.

Preforming method

Penoizol is ideally suited for the construction of demountable insulating casings for equipment and building elements where access to the main surface is required. According to the model or form, the hotel parts of the insulation are poured out and, after drying, are mounted in place. The only condition - it is required to ensure reliable protection of the insulation from mechanical damage.

Cons of foam isole

The main disadvantage of penoizol is its low tensile strength and compressive strength, which is lower than that of expanded polystyrene. Therefore, it is not permissible to use the material under the screed.

A sufficiently high hygroscopicity gives the material the ability to absorb condensate, but it can also be given off with the same ease. As in the case of mineral wool, it is necessary to ensure a decoupling at the lower boundary when the walls and the basement of the building are insulated, not allowing it to get wet.

Penoizol based on urea-formaldehyde at the stage of solidification not only releases water vapor, but also partially vapor forms of formaldehyde, but after 1-2 weeks the process of isolation stops. Immediately after application and until the insulation is completely dry, the emission of harmful substances does not exceed the maximum permissible concentration (maximum allowable concentration).

Most recently in the market of insulation products there was such material as penoizol. For our country, it is an innovation, although overseas insulation with penoizol has been used for more than 80 years. This heater has proved to be cheap, good thermal conductivity, soundproofing and durability.

Material Features

Peno-insulated products underwent a number of tests before they could enter the market. The material was certified and obtained a license from the State Standard.

Insulation with foam insulation improves the performance of the house. This is due to its individual structural features and properties.

Structure and composition of the insulation

The material is a foam in liquid form, but its thermal insulation properties are much higher than the analog. The thermal insulation material is obtained by foaming, and then the process ends with polymerization. It has a fine-meshed structure.

The main component of the thermal insulation material is resin. For preparation, various kinds of carbide resins are usually used. Also, the composition includes foaming agents and acids.

Low weight of the product is provided due to the high air content in the material structure. The transition to the foam-like form is due to mixing of the main components and compressed air.

At the exit from a special installation, a jelly-like substance is obtained. After solidification, the foam is a white light substance, reminiscent of the shape of marshmallows.

Specifications

Let's compare the main indicators of the heat insulator with the main competitors - basalt wool and expanded polystyrene.

As can be seen from the table for many indicators, penoizol bypasses its competitors. Also, the material has practically zero air absorption. With water, on the contrary - with prolonged contact, it absorbs it in large quantities, which leads to a decrease in thermal insulation properties. But if you exclude the source of moisture, foam after a while will evaporate all the liquid from its volume and return its quality indicators.

Application area

Penoizol can be used to insulate houses from any material due to its microcapillary structure. It allows any amount of moisture to pass through it outside the building.

Any structural elements of a building can be insulated by a foam insulation:

• walls;
• ceilings;
• partitions;
• floors.

It is used for both civil and industrial buildings. Penoizol has proven itself in rooms with high humidity, such as a sauna or a sauna. Also it is used for heat insulation of pipelines of heating systems, industrial units. A qualitatively executed installation will not only reduce the thermal losses of the building, but also provide a sound insulation of the house.

Benefits

The first indicator by which all heaters are characterized is the thermal conductivity. Y, in comparison with polystyrene, it is lower in two, and with mineral wool - three times. And with such good thermal insulation properties, the material has a low cost price.

The fine-mesh structure allows to "breathe" the heat-insulating layer. The vapors easily pass through the heater and do not form condensation. Due to this property, foam can be used even for wooden log houses. High fire safety - under the influence of open fire the material does not ignite and even at very high temperatures only the foam is evaporated.

The stability of the structure of the insulation is maintained even with very large temperature fluctuations. Also, it restores its volume after a slight compression. The undoubted advantage of foamed polystyrene foam is the good fillability of all the cavities of the walls, which can not be provided by a sheet analog.

One can not ignore the ecological factor as well - the thermal insulation layer does not emit toxic substances. Even when exposed to high temperatures, evaporation has a minimal percentage of toxicity and can not harm the owner of the house.

disadvantages

Like any building material, penoizol is not ideal and has its drawbacks and limitations in use:

• the material shrinks when drying is about 1%;
• it can not be used as a heater for the underground part of the foundation, because it absorbs a large amount of moisture and will lose its properties;
• it has a poor tensile strength, so it should be protected against mechanical influences;
• to install insulation you will need a special installation or specialist help.

Foam insulation installation technology

There are two options for pouring the heat insulator, which depend on the degree of readiness of the building object. Let's consider the features of both installation options for penoizol.

Warming of the finished building

Very often there is a need to reduce the heat losses of a house that has already been rebuilt. Penoizol is ideal if there are gaps and gaps in the floor or walls that can be filled with a heater. The technology is carried out in this order:

1. In the wall from the outside, in a staggered manner, holes are drilled, their diameter must be slightly larger than the size of the pipe.
2. Work must be done from the bottom up, for this, the tube is inserted into the hole and the pouring begins.
3. When penoizol starts to flow out of the hole, the process stops and a wooden plug is slammed into the hole.
4. Filling for this technology is made for each hole.
5. After frost-hardening the foam hole, the holes can be closed and the facing works carried out.

This option of insulation is suitable even for old and dilapidated houses.

Unlike polyurethane, liquid expanded polystyrene does not expand during hardening and will not lead to a breakdown in the structure.

Installation in the process of construction

The difference in the technology for working with such insulation as foam insulation and sheet products is the sequence of work. The sheet material is fixed to the walls and then covered with a vapor barrier layer. In the case of liquid foam it all happens differently. First, a hanging facade is built and then penoizol is poured under the membrane. In the case of brick masonry, it expels the outer and inner versts to the required height of the wall, after which the gap is filled with foam.

Warming can be done at any stage of construction. Floors with the help of foam can be carried out after the lags are installed. Between them the space is filled with foam insulation, the same can be done with the insulation of the ceiling of the house. Do not forget that penoizol is subject to mechanical influences. Therefore, on the floor it must be closed by the floorboard after hardening. On the roof should provide passage bridges, so as not to break the structure of the frozen heat insulator.

Penoizol is also good in that it can be used for cosmetic and overhaul repairs. It is used in cases where shrinkage of the old thermal insulation layer occurred or the heat insulator was damaged during the installation process. Penoizol will fix all the shortcomings, fill the voids formed and restore the insulation of the house.
