1. Protect the main structure of the building to extend the life of the building. Because the external thermal insulation is to place the thermal insulation layer on the outside of the structure, it reduces the stress caused by the structural deformation caused by temperature changes, and reduces the corrosion of the structure by harmful substances in the air and ultraviolet rays.
2. Effectively eliminate "thermal bridges" In the past, internal insulation was used. "Heat bridges" were unavoidable. The external wall insulation effectively prevented thermal bridges from forming and avoid condensation.
3. The moisture temperature of the wall is improved. Generally, internal insulation needs to be equipped with a vapor barrier, and the temperature permeability of the external thermal insulation material is far stronger than that of the main structure, and condensation generally does not occur inside the wall. The temperature of the entire wall is increased to further enhance the insulation performance of the wall.
4. It is conducive to the stability of the room temperature, and the external wall insulation is adopted. Because the structural layer with greater heat storage capacity of the wall is inside the wall, it is conducive to the stability of the room temperature.
5. Increase the use area of houses. It can avoid the damage of the second decoration to the insulation layer.
