Germany: Evonik’s Calostat insulation product has received an environmental product declaration (EPD) from the Institut für Bauen und Umwelt (IBU). The EPD takes into account the entire production process, from manufacture of precursors, their transport, production of Calostat and the option of recycling the material.
Calostat is a non-combustible thermal insulation material based on silicon dioxide.
It is a class A (non-combustible) building material with a thermal conductivity λ of 0.019 W/(mK). It does not absorb liquid water but is permeable to water vapour. Other distinguishing features are its compressive strength of ≥ 90 kPa and gross density of 165kg/m3. It contains no fungicides, algicides, pesticides, binding agents, or flame-retardants. Notably, the manufacturer also says that the product can be recycled.
