Insulation and decoration integration In the building exterior wall maintenance structure, the wall accounts for a large proportion. The heat dissipated by the wall is about 20% of the total heat dissipation of the building, and the heat absorbed by the exterior wall in summer is about 30% of the total heat absorption of the building. Therefore, the insulation design of the exterior wall is very important.

Exterior wall insulation materials can be divided into inorganic and organic. Whether it is summer or winter, the choice of exterior wall insulation materials depends on the thermal conductivity. The lower the thermal conductivity, the better the thermal insulation performance. The building uses rigid foam polyurethane with excellent waterproof performance. The lower the thermal conductivity, the better the insulation effect, and the lighter the weight of the overall integrated board.

The installation process of thermal insulation and decoration integration is more complicated than that of traditional thin plastering system, which saves more time and construction period. All are prefabricated in the factory, and the common size specifications are: 600mm*900mm or 600mm*1200mm. Special parts such as the corners of doors and windows are cut according to the on-site layout.

The integration of thermal insulation and decoration retains the thermal conductivity of ordinary thermal insulation boards, but enhances the thermal insulation effect of the product, and the construction process is more mature. It has a high cost-effectiveness and a broad market prospect. It has the advantages of stable quality batches, increased production capacity, and is not affected by the construction site environment. It has mature production technology and simple construction technology, a variety of colors and patterns, good flatness, and is not easy to deform, twist or crack, and has a wide range of applications.
