Foam glass is a porous glass foam material. Its advantages as a building material include its light weight, high strength and its thermal and acoustic insulating properties. It is made by heating a mixture of crushed or granulated glass and a blowing agent (chemical foaming agent) such as carbon or limestone. Near the melting point of the glass, the blowing agent releases a gas, producing a foaming effect in the glass. After cooling the mixture hardens into a rigid material with gas-filled closed-cell pores comprising a large portion of its volume.

In the 1930s, Saint-Gobain of France first developed foam glass with calcium carbonate as a foaming agent. In 1935, it applied for the first patent. Subsequently, in 1939, the Soviet Union experimentally produced foam glass at the intermediate pilot plant of the Mendeleev Institute of Chemical Technology.

The product that is known today as Foamglas® cellular glass insulation was invented by Pittsburgh Corning and was later acquired by Owens Corning. It is made of cullet, foaming agent, modified additive and foaming accelerator. After fine pulverization and uniform mixing, it is then melted at high temperature, foamed and annealed. Inorganic non-metallic glass material. It consists of a large number of uniform bubble structures with a diameter of 1 to 2 mm. Sound absorbing Foamglas® insulation is more than 50% open cell bubbles, and heat insulating Foamglas® is more than 75% closed cell air bubbles, which can be adjusted according to the requirements of use, through changes in production technical parameters.[1
