Briefly describe the advantages and disadvantages of metal exterior wall insulation decorative board technology

In China, 1 billion square meters of civil buildings are put into use every year. The proportion of building energy consumption to total energy consumption has increased from 10% in 1978 to about 30% today. Vigorous development of energy-efficient buildings has become a consensus. With the continuous improvement of the requirements for energy conservation and environmental protection, the insulation technology of building envelopes is also increasingly strengthened, especially the technology of metal exterior wall insulation panels has been greatly developed, and has become an important building energy-saving technology in China.

External wall insulation technology The external wall insulation used in construction mainly includes internal insulation, external insulation, internal and external mixed insulation. External wall external insulation is a building energy-saving measure that places the thermal insulation system on the outside of the outer wall to give the building good thermal insulation performance. In addition to the thermal insulation function, since the thermal insulation system is placed on the outer side of the outer wall, the temperature difference of the main structure is greatly reduced, and the temperature deformation is reduced, so that the metal outer wall thermal insulation decorative board can be used for the structural wall. To protect and effectively block the cold (heat) bridge, which is beneficial to the extension of structural life.
