What role does glass fiber mesh play in wall crack prevention?

Jul 22, 2025

When "glass fiber mesh" is used in the external wall insulation high-rise veneer brick system, the four-corner net is laid in the anti-cracking mortar, so that the anti-cracking protective layer of the external wall insulation brick is effectively strengthened, and then the glass fiber mesh is directly fixed to the structure through anchors, the surface load body is transferred, and the surface load is transferred to the base wall. The insulation layer can also be effectively protected. When subjected to external forces, damage occurs in the anti-cracking protective layer and is absorbed by the anti-cracking protective layer. Due to the good grip of glass fiber mesh and cement anti-cracking mortar, the mesh has a reasonable increase in tensile strength in the horizontal and vertical directions, greatly improving the strength of the base layer of the facing brick. Therefore, the use of "glass fiber mesh reinforced structure" can effectively take into account the unity between the anti-cracking performance and the requirements of the facing brick for the base strength, and meet the stability, safety and durability of the insulation system.
