Add to Cart
Cellular glass is a new inorganic thermal insulating material with a structure of equally closed cells. The composition is glass, added with foaming agent. It’s foamed by high temperature in foaming ove, and then cooled down in cooling oven. It well reserves the chemical stability of inorganic glass.
Features
1. Low density, low thermal conductivity and high compressive strength;
2. No water absorption, moisture permeability and leakage;
3. Small thermal expansion coefficient, good dimensional stability, no deformation and no cracking;
4. Fire protection, non combustion and corrosion resistance;
5. No mildew, no mouse sniffing, pest control and microorganism;
6. It is suitable for all kinds of harsh environments such as high temperature, deep cold, constant temperature and humidity.
7. Easy to cut, process and construct;
8. Inorganic products, no aging, no degradation of performance, service life synchronous with buildings;
9. Recycling, innocuity, safety and environmental protection.
