Advantage of stone wool board insulation and rock wool belt. 

     1. Fire protection: The external wall stone wool board insulation is made of natural volcanic rock, which is a non-combustible building material and fireproof material.
     Main fire protection characteristics: It has the highest fire protection grade A1, which can effectively prevent the spread of fire. Its size is very stable and will not stretch, shrink or deform in a fire. High temperature resistance, melting point higher than 1000℃. No smoke or burning droplets/fragments are produced in a fire. In a fire, no harmful substances and gases to the environment will be released.
     2. Hydrophobicity: The hydrophobicity of water-repellent stone wool board insulation products can reach 99.9%; the water absorption is extremely low, and there is no capillary penetration.
     3. Moisture resistance: In the environment of high relative humidity, stone wool board insulation has a volumetric moisture absorption rate of less than 0.2%. According to the ASTM1104 or ASTM1104M method, the mass moisture absorption rate is less than 0.3%.
