When renovating old residential areas, exterior wall insulation materials can greatly improve the effect of the entire roof. A building exterior wall protective decorative structure and a building exterior wall insulation wall structure belong to the category of building exterior wall construction technology, including a protective layer, a decorative layer and a topcoat that are arranged in sequence.

From the perspective of the building structure, the direction of the main section of the exterior wall is generally different from the direction of gravity, so the moisture on the surface of the exterior wall can be quickly drained under the action of gravity, which can protect the main structure and extend the life of the building. The cracks in the exterior wall insulation materials mainly occur in the board seams, around the windows, window corners, parapet parts, and the joints between the insulation board and the non-insulating wall. From the shape of the cracks, it can be divided into surface mesh cracks, longer longitudinal, transverse or oblique cracks, local bulging cracks, etc.

Exterior wall insulation can also play a decorative effect to a certain extent. Many friends think that the colors and textures of the exterior walls of buildings are directly made, but what everyone does not know is that most of these colors and textures can only be made using insulation boards.

A large amount of insulation materials can be used in the decoration process, so some construction sites will place a large amount of construction materials, or even all insulation materials on site. If the construction site area is limited, it will feel crowded. When mechanical fixation is used, the buried depth and number of anchors do not meet the design specifications, the bonding mortar ratio is inaccurate, and the selected cement does not meet the technical requirements. The bonding area is too small and does not meet the corresponding product design regulations.
