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 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, fire prevention, sound protection for building exterior insulation system.
Exterior wall rock wool board is mainly used for building wall and roof insulation and sound insulation, building partition wall, firewall, fire door and elevator shaft fire and noise reduction.

High compressive strength, tensile strength and durability index, which maintain the long-term stability and reliability of the product performance.
Rock wool does not burn, does not release heat and toxic smoke, fire can also effectively cut off the spread of fire, fire performance is good.
The thermal insulation performance is superior, which can improve the thermal resistance value of building envelope, reduce the building heating and air-conditioning energy consumption, energy saving and emission reduction.
It does not corrode the carbon steel, aluminum (alloy), copper and other metal materials and various components in the building.
The physical characteristics of sound absorption, noise reduction and elastic vibration elimination.
No moisture absorption, aging resistance, long term stability.
