What are the benefits of external wall insulation?

The wall outside the main structure of the external wall with high-efficiency thermal insulation materials is called the external thermal insulation composite external wall. The advantages of this wall include:

⑴The external thermal insulation material has a protective effect on the main structure. Outdoor weather conditions cause large temperature changes inside the wall, which occur in the external thermal insulation layer, avoiding large temperature changes in the internal main structure, and prolonging the life of the main wall.

(2) It is beneficial to eliminate or weaken the thermal bridge effect of excessive local heat transfer. If internal insulation is used, the thermal bridge problem is quite serious. The effect of thermal bridge will produce heat loss, produce condensation and condensation, cause damage to the building, and affect the service life.

⑶The main structure is on the indoor side, and due to the strong heat storage capacity, large fluctuations in room temperature can be avoided.

⑷ When the existing buildings adopt external thermal insulation for reconstruction construction, the interference to the residents can be greatly reduced.

⑸ Some residents have to redecorate their new houses. In the decoration, the inner insulation layer is easy to be damaged, and the outer insulation can avoid this problem.

⑹External insulation can achieve high economic benefits. Although the cost of external thermal insulation is higher than that of internal thermal insulation, as long as appropriate technology is adopted, the cost per unit area can not increase much.

However, due to the increase in the usable area compared with the internal insulation, the cost per unit of usable area is actually reduced. Together with the advantages of energy saving and thermal environment improvement, the overall benefit is very significant.
