~Exterior wall rock wool board is also called external wall thermal insulation rock wool board, rock wool board is raw material wall all kinds of natural rock, through natural rock after melting at high temperature, and high speed centrifugal equipment made of artificial inorganic fibers, adding a special binder and dust oil, and then cured by heating and generating exterior wall rock wool board we use!

Exterior wall rock wool board has high compressive strength and tensile strength, low water absorption and moisture absorption, good dimensional stability, does not produce the characteristics of thermal expansion or contraction, aging resistance, sound absorption, compatible with the exterior system, provide effective energy-saving insulation, sound-absorbing, fire protection for building exterior insulation system.

Exterior wall rock wool board is mainly used for building wall, roof insulation, wall construction, firewall, fire doors and elevator shaft of fire and noise reduction.
