Challenges/Characteristics

CFC and HCFC free

FOAMGLAS^® Insulation is completely free of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs ). Both can be released as byproducts during the manufacturing of plastic foams which are used as insulation materials.

CFCs cause damage to both the lower and upper (6 to 30 miles out) atmospheres. Damage in the upper atmosphere-sometimes referred to as the stratosphere) is particularly alarming because it depletes ozone.

HCFCs were seen to be a replacement agent for CFCs. However, they can be equally as bad or even worse than CFCs in terms of their greenhouse or warming effect on the world's climate.

Because FOAMGLAS^® Insulation is made of glass, it is completely benign as far as the environment is concerned. It consists exclusively of minute, sealed glass cells which are formed through chemically reacting finely-ground oxidized glass with carbon at a high temperature. No additional foaming agents, CFCs, HCFCs, organic binders or other potentially harmful substances are used that might contribute to atmospheric pollution.
