Later, exterior wall tiles began to be used, which have various patterns and colors and are very beautiful.

The integrated exterior wall insulation improves the dampness of the wall. In order to prevent condensation, the internal insulation layer needs to set an air layer, while the use of the external insulation layer does not require an air layer, and the external curtain wall surface layer will not be damp under the protection of the insulation material. Spraying a layer of paint on the outside of the insulation board can play a better waterproof effect. Basically, after the exterior wall layer is designed, there are rarely problems with leakage and seepage, especially for border friends, the waterproof effect of the insulation layer is very important.
