In my country, 1 billion square meters of civil buildings are put into use every year, and the proportion of building energy consumption in total energy consumption has risen from 10 in 1978 to about 30 at present. It has become a consensus to vigorously develop energy-saving buildings. With the continuous improvement of the requirements for energy conservation and environmental protection, the thermal insulation technology of building envelopes is also increasingly strengthened.

External wall thermal insulation technology The external wall thermal insulation commonly used in buildings mainly includes internal thermal insulation, external thermal insulation, and mixed internal and external thermal insulation methods. External thermal insulation is a building energy-saving measure that places the thermal insulation system on the outside of the external wall to endow the building with good thermal insulation performance. In addition to the thermal insulation function, because the thermal insulation system is placed on the outside of the outer wall, the temperature difference of the main structure is greatly reduced, and the temperature deformation is reduced, so the metal external wall thermal insulation decorative board can protect the structural wall. And it can block the cold (hot) bridge, which is beneficial to prolong the life of the structure {TodayHot}.
