Fiberglass grids are made by woven through special structure use E-glass fiber yarns (Major components is silicate with good chemical stability), then be treated of high heat setting with anti-alkali liquid, reinforcer etc. Alkali-resistant fiberglass mesh of interior wall insulation has characters of light weight, high strength, heat resistance, alkali resistance, waterproof, corrosion-resistant, anti-cracking, dimensional stability etc, can effectively avoid overall contraction of surface tension of the plaster layer and cracking caused by external forces, thin girds are often used in renovation and interior wall insulation. Grids of exterior wall insulation have characters of stable structure, high strength, good alkali resistanc, anti-corrosion, anti-cracking etc, its reinforcement effect is the best and construction is simple, easy, mainly applied in cement, plaster, walls, buildings and surface enhancement of other structures, is a new kind of construction material of exterior wall insulation project.
