The simple method for external wall insulation material is to first snap out the line, and it should be done uniformly. A relatively simple approach is to measure the overall dimensions, first piece together the boards to be constructed, and then uniformly draw lines on them according to the standard dimensions to keep all the pieces pieced together.

External wall insulation material is a structure in which insulation material is placed on the inner surface of the external wall through methods such as pasting, anchoring, batch coating, or masonry. External wall insulation commonly uses insulation materials such as insulation boards, insulation mortar, and composite insulation boards. In order to provide customers with greater choice, the new type of board offers more combinations of relief patterns and colors, giving architectural design greater room for expression.

The reason for the extruded plastic board of the external wall insulation material is likely due to production process errors or prolonged storage time by the merchant. Also pay attention to the raw materials of the product. Polyurethane insulation board is made by foaming black and white materials.

The simple method of using external wall insulation materials can also be applied to steel structure roofs. When used in steel structure roofs or walls, it can not only enhance the durability of insulation and avoid condensation, but also strengthen the firmness of the structure. Before applying polymer mortar on the bottom layer of the extruded board, it is necessary to clean the bottom surface of the board, apply interface agent on the surface, wait for it to dry until it is not sticky to the hands, and then evenly apply the polymer mortar on the surface of the extruded board, with a thickness of about 2mm as much as possible.
