1: Help the house to be warm in winter and cool in summer.

After external insulation, more heat can be stored indoors due to the increase of the heat capacity of the internal solid wall, which slows down the indoor temperature change caused by injecting solar radiation or intermittent heating, makes the room temperature more stable and improves the comfort of life. At the same time, in summer, the external insulation layer can reduce the comprehensive influence of solar radiation and outdoor high temperature, so that the internal surface temperature of the external wall and the indoor air temperature can be balanced and reduced. In winter, we can make better use of the free heat generated by comprehensive factors such as daily radiant heat, human body heat dissipation, household appliances and even cooking heat dissipation, which can save building energy.

2. External thermal insulation can prolong the service life of the main wall.

Because of the external wall insulation, the internal masonry wall or concrete is protected, and the outdoor climate is constantly changing, resulting in great changes in the internal temperature of the wall. In winter and winter, the temperature of the internal load-bearing wall increases, the humidity decreases, the temperature changes more smoothly and the thermal stress decreases, so the risk of cracking, deformation and damage of the load-bearing wall is greatly reduced and the service life is greatly prolonged.

3. External thermal insulation increases the decorative effect of the facade, which can make the building beautiful.

As long as the facade design of the building is well done, the appearance of the building will be excellent, especially in the transformation of old residential areas, external insulation can greatly improve the effect of the whole roof, so external insulation is widely used in energy saving of various public and civil buildings.

4. External thermal insulation can avoid thermal bridge.

The outer wall should not only bear the load, but also play the role of heat preservation, so the thickness of the outer wall must be increased. After using high-efficiency thermal insulation materials, the thickness of the external wall can be reduced appropriately. Because external insulation avoids thermal bridge, the heat loss of external insulation can be reduced by about 20% compared with that of internal insulation under the condition of using insulation materials with the same thickness, thus saving heat energy.
