Foam glass

Waste) glass is ground, mixed with other (inter alia gas generating) additions and processed into foam glass in so-called foaming furnaces. The product is available in different forms (boards or bulk material, etc.). Due to its properties as e.g. light weight, resistance against surface pressure and biological attacks (insects, mould formation), the application of foam glass is diverse, e.g. for insulation (heat, sound), sealing, drainage.
