Characteristics of rock sliver
● Sound absorption / sound insulation: the open structure of the rock sliver provides excellent absorption / sound insulation.
● Fire resistance: This product is detected by ASTM E-136 standard as non flammable products.
Pressure resistance: the rock wool strips are made from the pressing plate, and the fiber is upright in the assembly line process, so it can bear high load.
● 5%: stress resistance >25Kpa; 10%: stress resistance >40Kpa.
● Moisture resistance: rock wool is waterproof, with a good ability to release steam pressure from the roof structure.
