Add to Cart
Cellular glass is praised as "permanent thermal insulating material with no need of renewal", because it is not only safe but also durable in rigor conditions of low and cryogenic temperature, underground, open air, flammability, moisture sensitivity and even chemical erosion.
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.
