According to the design requirements, the exterior wall insulation materials can be pasted by the point frame method or the strip pasting method. After each piece of exterior wall insulation material is pasted, the ratio of the area of the special bonding mortar to the board area should meet the design requirements. The self-supporting and self-insulating prefabricated building exterior wall system uses the ridges and grooves of the exterior wall panels to plug and assemble the exterior wall panels along the outside of the original building beams and columns into an exterior wall body, and connects them through "L"-shaped connectors, one-way connectors, nested modules and I-shaped two-way connections.

When constructing the exterior wall insulation decoration integrated board, temporary protection measures should be taken for the entrances, passages, corners and other parts that may collide during construction and parts that may cause pollution. The construction of professional processes such as the installation of water and electricity equipment should be arranged reasonably and coordinated with each other in time. Then pay attention to the glue problem. If the quality of the glue is not good enough, degumming will occur, which will affect the final installation effect. High-quality glue should be used for installation, and the correctness of the glue should be ensured. If the lines where the insulation board needs to be pasted are, the distance between the crossbar of the scaffolding and the wall should be widened accordingly. Then, pay attention to the wall base plaster layer should not have sanding, hollowing, cracking and other poor quality phenomena, the plaster layer must have a sufficient maintenance period.

When installing the insulation board, it is strictly forbidden to work with electricity. When special circumstances require live work, strict protection measures must be taken during the construction of external wall insulation materials. All wires must be double-layer rubber sheathed wires. The wires must be overhead and firmly erected. They must not be tied to metal pipes or structures. External wall insulation materials have good thermal insulation properties. They can be used in buildings to improve the thermal insulation of buildings. Moreover, its application method is very simple, which can greatly improve construction efficiency.
