The base surface of the external wall insulation material at the internal and external corners of the wall should be sized and cut into boards, so that they can be vertically staggered and overlapped when pasted, ensuring that the corners are straight and vertical. The bonding of insulation boards should be installed in a horizontal order.

The structural layer that plays a role in thermal insulation in the external insulation system should be stored for as long as possible before use on construction sites. The specific storage time may vary depending on the production process, and it is generally believed that about 10 days from the factory to use is sufficient. By then, almost all physical and chemical reactions will have come to an end.

By meeting the same insulation requirements, the thickness of the building structure can be reduced, thereby increasing the indoor usable area. Strong deformation resistance, not easy to crack, stable and safe finish. Choose good insulation materials, take fire prevention measures for the initial stage of insulation material use, and carry out construction for the intermediate stage of exterior wall insulation material use.

The external wall insulation material has strict requirements for the smoothness of the base surface. If the surface of the base layer is uneven, use polyurethane foam to level it completely. Therefore, it is necessary to strictly require the flatness of the base layer, and setting out and marking points are the key to surface smoothness. When installing the insulation board on the wall, it is necessary to use a 2-meter ruler to repeatedly flatten it at any time and make it flush with the adjacent board surface to ensure the height difference between the boards. The circuit board should not exceed 1.5 millimeters to ensure the flatness of the insulation board.
