Cellular glass material that is obtained by heating to fusion finely ground glass powderwith a pore-forming material, such as coke, chalk, or dolomite. It is a good thermaland acoustic insulator and is easily worked and cemented. The average densityvaries from 100 to 700 kg/m3. Foam glass is used for the thermal insulation of refrigeration cars and undergroundpiping and as a buoyant material in rescue devices and pontoons. Filters for acidsand alkalies are made from foam glass with open pores.
Foam glass is absolutely safe, environmentally friendly insulator with unique properties and characteristics. Foam glass is the most durable and reliable at all known insulators today. Foam glass is inorganic insulator, which is consisting of cellular glass--a quantity of hermetically sealed glass cells.
