The integration of insulation and decoration is usually referred to as insulation and decoration integrated board, which has the main advantage of integrating insulation and decoration, eliminating many processes in construction. It cannot be polished in a parallel direction along the seam, and it also needs to move in a circular motion around the seam. Pay attention to moderate force, otherwise it may cause the unevenness of the extruded board surface to worsen.

The advantage of integrating insulation and decoration is that it can release the internal stress in the board, which can effectively avoid the occurrence of internal quenching in the board during long-term application, thereby reducing the insulation performance of the board and affecting its normal use. The waterproof layer is placed under the insulation layer, which ensures that the waterproof layer will not be damaged by external forces, nor will it age due to strong sunlight exposure. This not only extends the life of the extruded board but also reduces maintenance costs.

When using integrated insulation and decoration, it has been found that this product has a low thermal conductivity. Compared with other products, it has certain advantages of insulation, high thermal resistance, and low linear expansion rate. Generally, it is mainly used for insulation in freezers and inside and outside walls. In addition, the integration of insulation and decoration also has good high strength and compression resistance during use, which is mainly related to its special structure and requires special attention.
