The integrated external wall insulation board has good effect, long service life, and many construction schemes. It reflects the common product advantages in prefabricated building applications. It not only completes the waste of external wall decoration and insulation, but also completes the integrated board of external wall insulation decoration.

This material is generally bagged and needs to be configured according to the mixing ratio in the instructions. Use an electric stirrer to stir evenly in one direction, and then apply it on the insulation board for pasting. It can be roughly divided into two categories, one is the point sticking method, and the other is the point frame method.

The construction process requirements of the integrated external wall insulation board are relatively high. It is not that as long as you can do insulation, you can do an integrated board (unless you have done dry hanging stone, then it is easy to do this), so brothers should consider it clearly when taking on such projects. If there is no master to lead, don't take it over blindly.

The principle of stability of the insulation system without cavity or small cavity structure: the transmission direction of deformation stress. Prevent various deformation stress concentrations from occurring. This construction method makes the external wall insulation system have strong wind pressure resistance. It is set on the outside of the exterior wall and consists of an interface layer, a polystyrene powder insulation layer, an anti-cracking protective layer and a finishing layer (bricks or paint). It is a structural system that plays the role of thermal insulation, protection and decoration. When the temperature is high and the evaporation is large, the exterior wall insulation integrated board can be constructed in the shade and windproof place first; if it is done recklessly or hard or water is applied on the already dry polymer mortar, this place will definitely crack.
