Along with the improvement of the living standard of people, the proportion of building energy consumption must be further improved. In order to save energy consumption and protect the environment, the requirements on the heat insulation and heat preservation performance of buildings are higher and higher.

Therefore, the research on the form of external wall heat insulation and the novel heat insulation material has important significance for building energy conservation.
