What Is Foam Glass Insulation Material

Foam glass, also known as porous glass or foam glass, was first invented by Corning Company in Pittsburgh, USA.

The inorganic non-metallic glass material is made of cullet, foaming modifier and foaming accelerator after fine crushing and uniform mixing, and then after high temperature melting, foaming and annealing.

It is composed of a large number of uniform bubble structures with a diameter of 1-2 mm. Among them, sound absorbing foam glass is more than 50% of open cell bubbles. The thermal insulation foam glass is more than 75% of closed cell bubbles, which can be adjusted by changing the production technical parameters according to the use requirements.
