Around the windows of old houses, the aluminum alloy frame is only 2-4cm wide, and the thickness of the wall insulation material is 5cm, which will cover the window frame and even the glass. In addition, the window sill is not insulated. Therefore, most construction teams do not insulate the side walls around the windows.

Construction of external wall insulation materials around the windows of old houses

According to the height of the building, the corresponding fire isolation belt is set up, and fire protection measures should be taken during the construction process. However, among the commonly used insulation materials on the market, although the external wall insulation materials can reach Class A, the insulation effect is not good.

External wall insulation materials can collect excess heat. In buildings, insulation materials can be used to isolate indoor heat from flowing out, thereby playing a role in insulation. This effect of insulation materials makes it extremely popular in house decoration, especially in places with cold weather, and has good practical effects. This construction technology is simple, can reduce labor intensity and improve work efficiency; it is not affected by differences in structural quality. When constructing defective walls, the wall surface does not need to be repaired and leveled. It can be directly repaired with insulation slurry, which avoids the leveling and plastering of other insulation construction technologies.

The ratio of the sound energy absorbed by the material to the incident sound energy. This indicator has an impact on the noise of equipment and buildings. For example, the air-conditioning system of a building uses composite insulation of equipment and pipes, and selects materials with high sound absorption coefficients. Because sound elimination will greatly reduce the impact of noise. The wrong construction method of the exterior wall insulation material is one of the biggest reasons for cracking. Many construction workers did not stop construction according to the installation requirements. It left many construction hidden dangers, affected the construction quality, and caused cracking.
