Penoizol : characteristics and properties

penoizol What is unique?

distinguish it from analogue insulation it is that it is preparing the construction site and poured in place insulation - walls, attics, basements, floors.It has the form of a foam, which solidifies with the passage of time.Thereby significantly saves transportation resources, and many components of the fuel.

Plus, this material allows to fill in the most inaccessible areas (cracks, openings, cavities).If we talk about what has Penoizol characteristics, they are very similar to the properties of certain types of foam, but the scope of its use is much wider, and the price is lower.

Thus, thermal conductivity penoizol averages to 0.047 W / IBSC density of 8-28 kg / cubic meter, the compressive strength is 0,07-0,5 kg / cm2, and a flexural - 0,10-0,25 kg / cm2, and the total water absorption - 10.5-20.0%.At this operating temperature, at which Penoizol may be used range from -50 to + 120 ° C.The material itself is very technologically advanced, precisely because builders can fil

l up to 10-50 cubic meters / day, that is to carry out the work quickly.operation of a heater time is an average of 50 years.

Penoizol: advantages and disadvantages

Penoizol, the composition of which includes simple components, such as water, phosphoric acid, resin, a foaming agent, refers to cellular organic carbamide foam plastic.It may take the form of foams or plates.We describe its advantages:

  • The ease and simplicity of operation .Initial curing is just 15 minutes, the final - in 4-6 hours.
  • high sound and thermal insulation properties .Penoizol sheet having a thickness of 5 cm, is 100 centimeters brickwork.A thickness of 10 cm can significantly reduce heating costs.
  • Fire .It refers to the B-2 - flammability group and G-1 - flammability, T-1 - toxicity.This means that even if the surrounding material will melt the metal itself heater does not light.He is only able to slowly evaporate.
  • Hygroscopicity .It absorbs only 20% moisture.After drying, the material is completely recovers its characteristics.
  • Resistance to micro-organisms.It does not create favorable conditions for the development of mold and mildew.

By cons material is its shrinkage, which can be 0.1-5%.However, some experts find this a plus as well as expanding, the insulation is able to damage the structure of the building, and in this case this is not possible.Also refer to the shortcomings of its pernicious odor and harmful penoizol health.But this issue is also controversial, as it depends on the quality of the components, which are added by the manufacturer.

So if Penoizol harmful?

To deal with how Penoizol harmful, let's find out how the polymerization reaction.During drying, when the evaporation of the material can actually be allocated some gaseous substance (formaldehyde).Therefore there is a smell.To say that they are beneficial to human health, it can not be, because it is still chemistry.

But if we remember how dry paints and varnishes, they, too, has its own is not the most useful "flavor".The smell of penoizol disappears after its complete solidification.According to the producers themselves, the concentration of the lowest emissions of chemicals is low, confirming they present a health certificate and a certificate of conformity.Therefore, to lay this matter or not, you choose.After all, today the market offers a lot of natural insulation (eg, straw).
