External wall insulation rock wool board is A grade incombustible fire insulation materials, has high compressive strength and tensile strength, low water absorption and moisture absorption, good dimensional stability, will not produce thermal expansion or contraction, ageing resistance and other advantages, compatible with exterior wall system, offer effective heat preservation and heat insulation of the building, fire prevention and extreme climate protection performance.
Exterior wall insulation rock wool board product features：
1, High compressive strength, tensile strength and durability indicators, to ensure the long-term stability and reliability of product performance.
2, Rock wool does not burn, does not release heat and toxic smoke. When a fire occurs it can also effectively block the spread of flame, and fire resistance performance is excellent.
3, Thermal insulation performance is superior, can improve the thermal resistance of building envelope, reduce building heating and air conditioning energy consumption, energy saving and emission reduction.
4, Carbon steel, aluminum (alloy), copper and other metal materials and various components in the building are not corroded.
5, Physical characteristics with efficient sound absorption, noise reduction and elastic vibration elimination
6, No moisture absorption, aging resistance, long-term stability.
7, Light weight, can be cut or sawed, easy to process.
