thermal insulation materials rock wool board is a kind of non-combustible product whose melting point is above 1000℃. Our rock wool batts is a inorganic substance without any nutrient, and will not rot or breed any pests, it is not attached by any micro-organism.
Our stone wool mineral wool has features such as non-toxic, low thermal conductivity, hydrophobic, fireproof,sound-absorption, good physical and chemical stability. Doesnot use any CFC, HFC, HCFC or asbestos.
