Typical appication of exterior wall external insulation rock wool belt:

The belt is made into fireproof constuction by every one or two layer setting in accordance with a guarantee of at least 300mm width,and stick the whole area with the primary wall.
Application of rock wool belt making into exterior wall external insulation system with thin finish coat:
Using rock wool belt with the vertical fiber and processing as forms of external wall system with thin finish coat,applied to exterior wall,underground parking,store room and ceiling,whick can achieve higher tensile strength.Uniformity of materials assures the same insulation property and weather-resistance property in the whole integrate wall,and safe for fireproof.
Products must be stored indoors,when placed outdoor,covering with waterproofing cloth is required.
