On the one hand it can effectively increase the tensile strength of the protective layer, but it often selects some waste transparent plate glass, at the same time it should be troweled. It costs about 60 yuan. The retention rate of alkali resistant tensile breaking strength should be no more than 50%. Therefore the alkali glass fiber gridding cloth plays an important function and role in outer insulation system. The external angle should be at 200 mm or more. The alkali-resistant glass fiber gridding cloth purchased should be confirmed to be qualified before using: the lap width between alkali grid cloth lap width should be no less than 50 mm: 3×3×45 grams, 5×5×145 grams.
