Exterior wall insulation materials have multiple functions such as thermal insulation, waterproofing, and decoration, and meet the needs of energy saving in houses, so they are widely used. Holes and holes in the wall must be repaired, and the wall must be leveled. The flatness deviation must not exceed 4mm.

Walls form a large part of the external retaining structure. Therefore, the transformation of building walls and the development of energy-saving technology are one of the most important aspects of building energy-saving technology. The development of technology and energy-saving materials is the main way to achieve energy saving in buildings. When the exterior wall thermal insulation and decorative integrated panels are assembled as a whole, there must be a gap between them and the wall and roof. Exterior wall insulation and decorative integrated panels should be installed and leveled. The uneven areas should be padded with materials, and the hooks between the boards should be tightened.

If you build a house by yourself, install exterior wall insulation. Exterior wall insulation can directly isolate the impact of outdoor temperature and sunlight on the wall. Interior wall insulation is to isolate the impact of thermal radiation from the wall on the interior. Commonly used materials for interior wall insulation are extruded boards, rock wool boards, and polystyrene boards.

The key points of the construction of exterior wall insulation materials are still very important. Everyone needs to pay attention to these points during construction. Building paint/toned cement mortar should be used for the exterior panel layer, and the performance of the system should meet the requirements. In external insulation projects (especially for thin plaster exterior insulation systems), the size deviation of the plaster layer and facing layer depends largely on the base layer. Therefore, the dimensional deviation of the base layer must be qualified. The wall should be clean and free of oil stains, floating dust, etc. The old wall should be free of loose and weathered parts.

Before the construction of exterior wall insulation materials, a thorough inspection of the exterior wall of the project must be carried out. For tools, use a 2M ruler. The deviation should not be less than 4mm. The excess part should be leveled or removed. If there are grooves, you can use some cement mortar to repair them.
