What is the uniqueness of penoizol?
The difference from analogue heaters is that it is prepared exactly on the construction site and poured into the place of insulation - walls, attics, cellars, floors. It has the appearance of a foam that solidifies with time. This significantly saves transport resources, fuel and many components.
Plus, this material allows you to fill the most difficult areas( cracks, openings, voids).If we talk about what has a foam isole characteristics, then they are very similar to the properties of some types of foam, but the scope of its use is much broader, and the price is lower.
So, the thermal conductivity of foam is an average of 0.047 W / mChK, the density is 8-28 kg / m3, the compressive strength is 0.07-0.5 kg / cm2, and with bending - 0.10-0.25kg / cm2, and the total water absorption is 10.5-20.0%.The operating temperatures at which penoizol can be used range from -50 to + 120 ° C.The material itself is very technological, which is why builders can fill up to 10-50 cube / day, that is, perform work promptly. The service life of the heater is 50 years on average.
Penoizol: disadvantages and advantages
Penoizol, which contains simple components such as water, orthophosphoric acid, resin, foaming agent, refers to cellular organic carbamide foams. It can have the appearance of foam or slabs. Let's describe its advantages:
- Ease and simplicity of operation .Initial curing takes place in just 15 minutes, the final curing takes place in 4-6 hours.
- High sound and heat insulation properties of .The sheet foam isole, having a thickness of 5 cm, is equal to 100 centimeters of brickwork. A thickness of 10 cm can significantly reduce the cost of heating.
- Flameproof .Refers to B-2 - the group of flammability and G-1 - flammability, T-1 - toxicity. This means that even if metal is melted around the material, the heater itself will not light up. It can only slowly evaporate.
- Hygroscopicity .Absorbs only 20% moisture. After drying, the material completely restores its characteristics.
- Resistance to microorganisms .It does not create favorable conditions for the development of fungus and mold.
The disadvantages of the material include its shrinkage, which can be 0.1-5%.However, some experts find this a plus, as expanding, the insulation can damage the construction of the building, but in this case it is impossible. Also, the disadvantages include its harmful odor and the harmfulness of penoizol for health. But this question is also controversial, since it directly depends on the quality of components that manufacturers add.
So, is penoizol harmful?
To understand how much penoizol is harmful, let's find out how the polymerization reaction occurs. During drying, when evaporation occurs, some gaseous substances( formaldehyde) can indeed be released from the material. That's why there is such a smell. To say that they are useful for human health, it is impossible, since it is still chemistry.
But if we remember how the paints and varnishes dry up, they also have their own not so much useful "fragrance".The odor from penoizol disappears after it has completely solidified. According to the manufacturers themselves, the concentration of the released chemicals is minimally low, in confirmation they present a hygienic certificate, as well as a certificate of conformity. Therefore, to lay this material or not, choose you. In the end, now the market presents a lot of natural insulation( for example, straw).
