The exterior wall insulation decoration integrated board can play a good waterproof effect, and can prevent the insulation layer from falling off, and efficiently and permanently protect the exterior wall of the building. The formed coating is hard and wear-resistant, with high hardness, and has the characteristics of waterproof, anti-corrosion, acid and crack resistance, so that the outer wall forms a wall insulation material-wall system, so as to achieve the effect of insulation and energy saving. It is a large-area roll waterproof layer and a large-area polyurethane waterproof coating waterproof layer roof for industrial and civil buildings.

The size of the polystyrene board for the exterior wall insulation decoration integrated board is 1200×600mm. Non-standard sizes or local irregularities can be cut on site, but it must be noted that the cut is perpendicular to the board surface. The insulation board should be arranged in staggered seams (see Figure 4) at the corners of the entire wall. According to current regulations, the warranty period of the exterior wall is two years, and after two years, maintenance will also be difficult. For this reason, it is necessary to re-design the scheme or preliminary design through construction drawing review or due to design changes.

The waterproof effect of the exterior wall insulation decorative integrated board is good, and the thermal insulation fiber tube, finishing layer, processing technology and other aspects analyze how to choose a suitable exterior wall insulation integrated board. The greater the relative density, the better the actual sound absorption effect. There are corresponding energy-saving and insulation requirements for large buildings in various places (the material thickness is calculated by the thermal conductivity of the insulation material to meet the insulation and energy-saving requirements). Energy-saving building insulation, of which the exterior wall accounts for the largest proportion.

The construction speed of the exterior wall insulation decorative integrated board is fast, but there are also problems. The insulation layer is made inside the wall, which reduces the use area of the commercial housing; it affects the secondary decoration of residents, and heavy objects such as decorative paintings cannot be hung on the indoor walls, and it is easy to hang and fix objects on the interior walls.
