If the exterior wall insulation decorative panel is not flush with the plane line, adjust the fine-tuning pendant, adjust it to be flush, and then tighten the bolts. Steel expansion connection aluminum alloy hangers are used to strengthen the anchorage at the position of each floor frame beam, and separate fire isolation belts are set at the position of each floor beam.

Decorative materials and insulation materials are independent products, purchased by users from different manufacturers and constructed by different work units. The external wall insulation and decoration integrated board has both insulation and decoration functions, achieving full insulation and decoration of the exterior facade. It does not produce gas and smoke, and can effectively prevent the spread of fire, fully complying with flame retardant standards. At the same time, it has the ability to resist external impact, insulation, waterproofing, lightweight and not easily broken or damaged, making it an environmentally friendly material.

The construction of external wall internal insulation is simple, the cost is relatively low, and the construction technology and inspection standards are relatively complete. However, there are the following problems: it is difficult to avoid hot (cold) bridges, which reduces the insulation performance, and the external wall internal surface at the hot bridge part is prone to condensation, moisture, and even mold.

The interlayer adopts methods such as backing board insulation and double-layer glass curtain wall system to achieve the purpose of insulation and energy saving. Traditional insulation methods are mainly used for insulation in dry hanging stone or aluminum curtain walls, such as using EPS, rock wool, foamed polyurethane, etc. as insulation materials. The scope of treatment is from covering the mountain wall with soil to the hidden corners of the roof and other local hollowing and cracking areas on the facade. The alkali resistant mesh cloth at the intersection of the treated and untreated exterior walls should be overlapped by 100mm, and 100mm should be reserved for the large corner of the mountain wall.
