With glass fiber woven fabric as base material, gridding cloth is dipped in and coated with highly resistant polymer emulsion, thus featured by good alkali resistance, flexibility and high tensile resistance in the bidirection of warp and weft. It is widely used for thermal insulation, water proofing and crack resistance of internal and external walls of buildings. The glass fiber gridding cloth mainly adopts alkali glass fiber yarn (with silicate, stability as main components) and made by high-temperature heat setting such as anti alkali liquid and strengthening agent of the special organization structure - lace stitch.
