Introduction
Technical Data
Application
Resource
Rock wool board uses high-quality basalt as raw material whose melting point is above 1000 ºC and has good effects on heat insulation and sound absorption. It has good properties of fire resistance, pest proof, corrosion resistance, stable chemical property and free-asbestos and safe to human bodies.
 
Small coefficient of heat conductivity and good capability of heating preservation.
Outstanding effect of energy-saving.
Excellent fireproof capability. Excellent sound absorption and sound insulation capability.
Green thermal insulation materials and no harm for body.
Waterproof.
The folded rock wool board with certain compression resistance has greater drawing strength, and it does not tend to peel off and has excellent improved durability.
