The use of foam board
1. Protect the main structure of the building and prolong the life of the building. Since the external thermal insulation is to place the thermal insulation layer on the outside of the structure, the pressure caused by the structural deformation caused by the temperature change is reduced, and the erosion of the structure by harmful substances in the air and ultraviolet rays is reduced.
2. Effectively eliminate "thermal bridges" In the past, internal insulation was used, and "thermal bridges" were unavoidable, while external wall insulation effectively prevented the generation of thermal bridges and avoided condensation.
3. The tidal temperature of the wall is improved. Generally, a vapor barrier is required for internal thermal insulation, while the temperature penetration performance of external thermal insulation materials is much stronger than that of the main structure, and condensation generally does not occur inside the wall. The temperature of the whole wall is increased to further enhance the thermal insulation performance of the wall.
4. It is beneficial to keep the room temperature stable, and the external wall is used for thermal insulation. Since the structural layer with a large heat storage capacity of the wall is on the inner side of the wall, it is beneficial to keep the room temperature stable.
5. Increase the usable area of the house. It can avoid the damage to the insulation layer caused by the second decoration.
