The specifications, varieties and performances of various materials for integrated exterior wall insulation and decoration meet the design specifications and relevant regulations. After the materials are delivered, they must be sampled and re-inspected according to the construction specifications, and it is strictly prohibited to use materials that do not meet the regulations in the project.

The bonding area of the insulation board directly affects the bonding firmness of the insulation system. During the construction process, due to insufficient coating or incorrect coating method, the effective bonding area between the insulation board and the foundation wall cannot meet the requirements of more than 40%.

The anti-compression measures are unreasonable. The surface load of the insulation board is too large, or the negative wind pressure resistance measures are unreasonable. The bonding and anchor bolt anchoring construction is unreasonable. In the process of bonding the integrated exterior wall insulation and decoration, the flatness of the wall base does not meet the requirements. For example, certain reinforcement measures should be taken for rock wool. In addition, materials such as insulation mortar and foamed cement board will have a significant decrease in their own strength after absorbing water, and they should also be used in the integrated exterior wall insulation and decoration system.

When the adhesive for integrated exterior wall insulation decoration is fully applied, leave 30-50mm on the upper and lower margins of the insulation board, the spacing of the scraped strip mortar is 40-60mm, the width of the adhesive strip is 80-100mm, and the adhesive area is not less than 70% of the board surface area. The wall material itself has the function of energy saving and heat insulation. The purpose of energy saving and heat insulation can be achieved by selecting appropriate insulation materials and adjusting the wall thickness. Common self-insulation materials include: steam pressurized concrete and shale sintered hollow blocks.
