The concrete roof is used, and the outer wall waterproof layer extends to the drip line on the inner side of the roof. The outer wall waterproof layer extends to the door and window frames, with reserved grooves. Adjust the flatness of the board surface and the vertical and horizontal width of the grid. The first panel of the bottom layer should be carefully installed according to the wall reference line, and fixed anchor fasteners should be installed above and below the dividing joints. The anchor fasteners must be anchored in the grooves of the insulation decorative panel surface.

The standardized production of factories has greatly improved the current situation of on-site construction of traditional exterior wall insulation systems, enhanced safety performance, and implemented integrated factory production, ensuring quality and not being affected by on-site construction. The processing insulation panel adopts galvanized steel plate with a thickness of ≥ 0.25mm, which improves the seismic and compressive performance of the steel plate and solves other problems such as wall cracking, cavitation, and detachment caused by previous construction.

After interface treatment on the base wall, polystyrene particle insulation slurry is directly applied, and then a crack resistant mortar surface layer is made, reinforced with fiberglass mesh cloth. Other commonly used insulation materials include composite silicate insulation mortar, sepiolite insulation mortar, perlite insulation mortar, and rare earth composite insulation mortar.

In recent years, due to the demand for building technological upgrades, there has also been a method of using insulation materials such as post poured air cement to achieve insulation effects in the cavities of curtain walls. The traditional method of waterproofing the exterior wall is often used in western-style houses or cultural tourism projects. Apply interface agent between the polyurethane insulation layer and its outer vitrified microsphere leveling layer. The outer side of the glass bead leveling layer is painted with floral paint for the exterior wall. The reason for this situation on site is that the interface agent between polyurethane and vitrified microbeads is not evenly applied, causing the exterior wall to fall off together.
