The original intention of exterior wall insulation materials is to make buildings more energy-efficient, better maintain the main body of the building to extend its service life, and improve the utilization rate of indoor space. Once cracks appear on the surface layer of the exterior wall insulation material, the overall insulation performance of the wall will be greatly reduced, and the energy-saving effect will be difficult to meet the designer's initial design requirements, and cannot meet the mandatory requirements of the specification for energy-saving effects.

Ensure the quality and safety of exterior wall insulation material buildings. Before pasting the rock wool board, L-shaped stainless steel brackets are set at each floor slab and suspended parts such as door and window openings. The horizontal spacing of the brackets is not more than 600mm. During construction, a horizontal line needs to be drawn to arrange the brackets in a horizontal direction. When the mesh is laid horizontally, the glue should be pressed densely, and there should be no hollowing, warping, etc. The horizontal overlap width is greater than 100, and when the longitudinal width is greater than 80, the thickness of the polymer mortar shall not exceed 4, and one layer shall be less than 5.

Improve the management process of exterior wall insulation material buildings, and take timely measures to avoid unnecessary delays and losses caused by problems in a certain link during construction. The panels are arranged in a horizontal order, and the upper and lower seams are pasted, and the yin and yang corners are staggered. When gluing the boards, the mortar overflowing from the board edges should be evenly removed so that there is no glue "joining" between the boards. The weld should be strict, the weld width should be greater than 2mm, and filled with polystyrene boards of corresponding thickness.

If the ash layer of the exterior wall insulation material is too thick, it is easy to cause a large gap between the polystyrene board and the wall after it is laid and fixed, affecting the later use effect, so it can make the building more energy-efficient.
