Rock wool as A1 grade non-combustible material, rock wool main raw material is basalt or diabase, non-flammability and fire resistance.
ROCK wool is made of the volcanic rock and rock wool products belong to inorganic silicate fiber, its anti-burning properties to A1 level, that is, non-flammable materials requirements. Rock wool fire resistance is to maintain the stability of the system structure in the event of a fire, can effectively prevent the flame spread, dimensional stability, non-telescopic deformation, melting point higher than 1000 ℃. Different thickness of rock wool and other materials with, you can achieve 1-4 hours of fire resistance.
1 ,breathable, wall is free to breathe performance.
2 ,Metal materials and components do not corrode.
