According to the characteristics of the external wall insulation board, the selection of the reinforcement mesh is also in accordance with certain requirements.

The application of glass fiber mesh in the external insulation technology of external walls has been rapidly developed as a key reinforcing material for the soft input of the anti-cracking protective layer. On the one hand, it can increase the tensile strength of the protective layer. The cracks that could have been generated are dispersed into many finer cracks, thus forming an anti-cracking effect. Since the outer protective cracking mortar of the thermal insulation layer is alkaline, the long-term alkali crack resistance of the glass fiber mesh is of decisive significance. In terms of durability, high alkali-resistant fiber mesh is much more durable than alkali-free mesh and medium-alkali mesh, and can meet the requirements of at least 25 years of use. Therefore, in the selection of reinforcement mesh , it is recommended to use a high alkali-resistant mesh cloth.
