The use of thermal insulation and decoration integration in engineering construction must start with basic materials, such as the geographical environment and geological conditions of the construction site, what materials and equipment to use, and collect information to control the project cost in advance.

"Water repellency" is an important performance indicator that reflects the water penetration resistance of materials. The water repellency of the thermal insulation core material of the thermal insulation and decoration integrated energy-saving composite board of the building is as high as 99.2%-99.6% under standard experimental conditions, and has excellent air permeability.

When designing the exterior wall insulation project, the engineering designers will include window edges and shrinkage cracks in the design, strictly control the detailed materials, and strictly improve the thermal bridge effect and waterproof treatment. The exterior wall insulation board materials must be staggered and assembled, with a staggered seam of no less than 100mm, and pay attention to the joints in the wall.

Shear stress is generated between the layers of the thermal insulation and decoration integrated structure. If it exceeds the shear strength generated by the bonding between the two layers of the structure, some of the bonding surfaces will form hollows until cracking occurs. There is a common problem of insufficient mortar mixing time at the engineering site, which causes uneven dispersion of the various component materials in the slurry. The construction site only needs simple assembly, and the process is very simple, which greatly shortens the construction period and reduces the comprehensive cost of each link. It can achieve classical style, modern style, European style, American style and other styles, bringing more diverse exterior wall styles to everyone.
