Its basic structure is that the insulation layer is bonded to the outer surface of the wall through adhesive, suitable for external insulation structures of new and renovated walls. After pasting the insulation board, we need to decorate the surface layer. The surface of ordinary insulation board is decorated with granular elastic paint and stone spray paint. Regardless of the method. When spraying real stone paint, attention must be paid to whether there are cracks, otherwise there is a risk of water leakage.

The performance of the external wall insulation adhesive does not meet the required standards, and the adhesion is insufficient. The water resistance and freeze-thaw resistance of external wall insulation board directly affect the bearing capacity of external wall insulation, leading to cracking and swelling caused by natural factors. Even when installing curtain boxes and radiators, it is difficult to hang them on walls with internal insulation. In the renovation of old buildings, there are issues with internal insulation such as movement, disturbance to residents, and even temporary relocation, which will reduce the usable area.

The outer side of the main structure of the building is made of insulation material. The main structure consumes a large amount of heat during daily, seasonal, and annual cooling and heating cycles, which proves that external insulation is a form of insulation that wastes energy. The usage area of internal insulation is related to the lack of internal insulation measures, and the inner side of the wall still needs to be painted with cement mortar surface.

The use of internal insulation materials is very limited. For the issue of internal insulation affecting residents' secondary decoration, firstly, internal insulation can only be carried out on the inner side of the exterior wall, not on the internal partition wall. Secondly, it should be addressed by establishing citizens' awareness of energy conservation and establishing a market mechanism for isolation walls. This utility model overcomes various disadvantages of internal insulation and has good insulation effect. It is a new technology used for the exterior wall enclosure structure of high-rise buildings. It should be noted that when purchasing, attention should be paid to whether the content of the product label meets the standard requirements. When signing the contract, the execution standards, classification, specifications, and dimensions should be specified.

The main advantages of external wall internal insulation are: fast construction speed, simple and sensitive operation, which can ensure construction, long application time of internal insulation, exquisite technology, and relatively complete construction technology and inspection standards. The increase in fire accidents caused by building exterior wall insulation materials has also caused a huge response in the industry, with some construction contractors suffering heavy losses. How to seek the transformation of insulation material production enterprises is an inevitable problem in the production of new insulation materials.
