Exterior insulation and alkali is a special mesh cloth or E-glass fiber woven fabrics based coating formed by the alkali. The product high strength, good alkali resistance, thermal insulation structure of the system plays an important role, mainly to prevent cracks. Due to its excellent acid, alkali and other chemicals Furu performance and the warp and weft tensile strength, external wall insulation system to make the stress evenly dispersed, to avoid the collision outside the momentum, the heat caused by compression structure of the deformation, so that the insulation layer has a high erosion force strength, and ease of construction and quality control, thermal insulation system in a "soft steel" role.
