Preparation of external wall insulation construction materials: Purchase the required insulation materials, ceramic sheets, adhesives and other related construction materials, and check whether the materials meet the requirements. When installing self-insulating external wall panels, you should choose appropriate installation tools, and measure and calculate before installation to make the size of the self-insulating external wall panels accurate. During the installation process, the surface flatness and verticality of the self-insulating external wall panels should be checked to ensure that they meet the standard requirements.

External wall insulation mortar needs to be used in layers and used slowly in combination with the design. The thickness of the general residential external wall composite insulation board is 2.5 cm. The construction surface angle should not be too large, and the speed should be slow. This place needs to be pressed well. Before construction, construction personnel need to receive relevant technical training and information disclosure education. After each process is completed, it needs to pass the inspection of the quality inspection department before the next construction process can be carried out. Anchor bolts are required for anchoring during installation.

Building external wall insulation materials are suitable for a wide range of temperatures. It can be used at -200℃~200℃ for a short time and at 140℃~160℃ for a long time, which is better than polystyrene foam (80℃) and polyurethane foam. When applying decorative surface to buildings, apply base mortar on the insulation layer, press alkali-resistant glass fiber mesh cloth (alkali resistance strength retention rate is not less than 90), and then use polymer cement mortar for leveling. If necessary, use flexible putty, and use multi-layer paint or real stone paint.

Fireproof construction of exterior wall insulation materials has certain requirements for ambient temperature. Generally, the operating ambient temperature should not be lower than 5℃. If construction is required in winter, corresponding antifreeze measures need to be taken. Secondly, try not to construct in windy and rainy weather, and take corresponding measures.
