Foam glass is new inorganic thermal insulating material with a
structure of equally close cells. The composition is
glass added with foaming agent. It is foamed by high temperature in
foaming oven and then cooled down in cooling oven.
As a result it has following characteristics: low density, low
thermal conductivity, vapor impermeability, high mechanical
strength but can easy to cut and also able to bear all kinds o
chemical erosious except the hydrofloric acid
