The construction of the exterior wall insulation decorative integrated board is particularly important. The exterior wall insulation decorative integrated board of the building is prefabricated in the factory. The flexible board processing method greatly improves the installation of the board and the efficiency of the project construction. The exterior wall insulation decorative integrated board belongs to the insulation system. The insulation material is the core of the system.

The quality of the exterior wall insulation decorative integrated board itself and its installation is directly reflected in whether the quality goal of the insulation system can be achieved. The use temperature of the insulation material is also very important. This can be said to be a basis for selecting insulation materials. When using it, we need to choose different insulation materials according to the temperature of different places.

Due to the large heat capacity of the inner solid wall, after adding the insulation layer outside the wall, the change of indoor temperature will slow down, and the stable room temperature is conducive to energy saving. In summer, the external insulation of the facade reduces the transmission of solar radiation heat and the influence of outdoor high temperature, so that the building is warm in winter and cool in summer. Use special bonding mortar, the back of the insulation decorative board is arranged, and the point bonding method is adopted. The bonding point arrangement requirements: no less than 5 bonding points per board and the bonding area is not less than 40%. The compression setting thickness of the bonding layer is 3-8mm. First, mix the special bonding sand evenly.

The alkali-resistant glass fiber mesh cloth for integrated exterior wall insulation decoration must be qualified before it can be used. In the control of exterior wall insulation cracks, not only the insulation layer material is required to have a certain tensile strength and ultimate tensile strength, but also the anti-cracking protective layer material is required to have sufficient tensile strength.
