Technical regulations and acceptance regulations for the application of external wall insulation materials, supporting materials, special construction machinery and system integration technology, connection technology, as well as wall material product catalog design and wall material component certification system to promote the development of general systems. Due to the hydrophobicity of polystyrene boards and conventional hydrophilic materials, the subsequent construction quality outside the surface layer is difficult to guarantee, and it is easy to have quality problems such as cracking, falling off, and hollowing of the surface mortar, which restricts the use of exterior decoration of buildings such as tiles and coatings.

The maximum anchoring thickness of most external wall insulation and decorative integrated panels is only related to the anchor bolts. The thickness of the insulation material, the thickness of other load-bearing structural materials and the thickness of the bottom adhesive are comprehensively compared to determine the effective thickness of the anchoring. The impact point should be selected according to the different performance of the plastering layer and the finishing layer. Use swing impact. Take the height difference between the position where the steel ball starts to fall from rest and the impact point equal to the specified drop.

The measurement of wiring is also very important in the construction of the integrated insulation and decoration panels for external walls. The measurement of wiring must be combined with the layout. It is necessary to not only meet the economic benefits, but also pay attention to the aesthetic effect. In order to ensure the quality of construction, skilled personnel are required to complete the work.

In addition to the insulation test, the acceptance procedures for the integrated insulation and decoration panels for external walls also require the testing of the waterproof performance of the enhanced external walls, because the wall surface needs to be waterproofed before the external wall insulation is installed, and a layer of paint must be sprayed on the outside of the insulation board to play a better waterproof role. Safety (insulation system) requirements are more professional, and the performance of the insulation system components (weather resistance, hydrophobicity, air permeability, impact resistance and fire resistance level) are required to be higher. The anti-cracking function of the cover layer material is required to be higher, and it should have higher water resistance and waterproofness.
