Insufficiency of metal exterior wall insulation decorative panel technology:

1. Compared with foreign countries, the external thermal insulation construction in China is more difficult. This is because my country has less land and more people, and the urban population has a high density of living. The residential building structure is mainly multi-storey and high-rise buildings, while foreign developed countries are mainly low-rise and a small number of multi-storey buildings. cast-in-place concrete shear wall structure of high-rise residential building. In this way, the objects targeted by domestic external wall thermal insulation are much larger in area and height than foreign building structures, and the construction is also more difficult.

2. The technology of some external thermal insulation products is not up to standard. When the wind blows, the thermal insulation layer is often blown off. It is difficult to deal with cracks in the external thermal insulation layer, which hinders the promotion of external thermal insulation technology. Therefore, it is suggested that relevant departments should refine the technology and construction standards of metal exterior wall thermal insulation decorative panels, strictly approve the system, and raise the entry threshold.
