The wuzhou bubble summed up the five advantages of building external wall insulation.

1. It can reduce the disturbance to the residents. In the decoration, when the building adopts the external insulation for renovation and construction, the inner insulation layer is easily damaged, and the external insulation can prevent the decoration from damaging the insulation layer.

2, its heat preservation and heat insulation effect is better than that of insulation, because of the external wall insulation board material posted on the outer edge of the wall, external thermal insulation can reduce the construction cost, increase the using area of the building, to achieve higher economic benefits.

3. The use of external wall insulation board is conducive to the elimination or reduction of the influence of thermal Bridges in the surrounding area of the junction of the inner and outer wall, the wall enclosure, the constructional column, the frame beam and the top parapet and the roof panel.

4. Due to the strong thermal storage capacity, the main structure is on the indoor side. It is beneficial to the thermal stability of the room, which can prevent the large temperature difference at room temperature and improve the wetting condition of the wall.

5. The temperature data of external wall insulation board has a protective effect on the main structure, as the insulation layer is placed outside the building enclosure structure. Outdoor weather conditions caused the wall temperature changes within the larger, outer insulating layer, buffer the structure forms of stress caused by temperature change, prevent large temperature changes in the internal structure of the main body of effectively improve the durability of the main structure, building life extension.
