Low coefficient of thermal conductivity

The foamglass granulate detains warmth due to the structure of granules – the fine pores inside as if “lock” the air inside of the granule. Therefore, the thermal conductivity coefficient ƛ is between 0.059 and 0,08 W mK.



The foamglass granules are resistant to compression fin the cylinder from 1.5 to 2.5 MPa. This feature does not change during the entire maintenance period.


Fire resistance

The constructions with foamglass are more fire-resistant. The chemical composition of the main component is just simple blown silicate glass, consisting of the molten highest oxides, which do not evaporate or burn. The operating temperature regime of foamglass granulate is from-200°Cto750°C.

Humidity resistance

The unique structure of the foamglass granulate prevents absorbing more than 10% of water from total volume even if it is completely immersed into water. This happens because the granule is covered by the fusion layer. It is very important that water absorption does not increase with time and the material maintains all the initial thermal                                      insulation characteristics and stability.

Chemical and biological persistence

The foamglass granulate is completely resistant to the impact of organic and inorganic chemical reagents (the only exception is fluorine hydrogen acid that is used to melt glass). Besides, the foamglass is resistant to the biological impact; it does not decompose or decay. None of the known biological microorganisms has the possibility to exist in                        it and it is not eaten by rodents. 


This inorganic material is completely friendly to the environment, because it is simply a glass. When in use, and under the effect of changing temperatures or humidity,no chemical substances are generated.



Due to the closed cavities inside of the pores of the foamglass granulate, this material remains unchanged for many years, thus its exploitation period is indefinite.
