The main function of external wall insulation integration is to reduce the surface area of the building's external structure, and to use materials with low thermal conductivity, that is, materials with high heat transfer resistance, as the external components of the building, which is an important way to reduce the heat transfer through the external structure. This is because it takes the building facade of the entire wall as a block for overall construction during construction. In this way, it is impossible to prevent some weak points from being unprotected in time, and the entire wall is exposed to air, heat and sunlight.

External wall insulation integration is mainly composed of adhesive layer, thermal insulation decoration integrated board, sealing material, anchor, etc. There are many construction schemes, which can be used for wall insulation of various commercial buildings and residential buildings, and are also suitable for the north. After a long time, it is easy to crack, and in severe cases, it may break and leak. This is because after the waterproof layer is completed during the construction process, only a layer of mung bean paste is sprinkled on it.

The bonding surface of the exterior wall rock wool board should be pre-treated during construction. First, apply a layer of inorganic adhesive of appropriate thickness to allow it to penetrate into the fiber of the rock wool board. The surface area covered by the mortar surface should be no less than 50%. Therefore, it only needs to be directly pasted to the wall with special mortar to achieve the required bonding strength requirements. Material quality, only high-quality materials can achieve the expected use effect, and materials with quality problems will not only fail to achieve the expected use effect, but may even cause engineering quality problems.
