When insulation boards or insulation granular materials are used as insulation layers, a complete insulation surface cannot be formed, and the expected insulation effect cannot be achieved. will have varying degrees of impact.

2. Spraying the waterproof layer has high requirements on the dryness of the substrate, which requires equipment to enter the construction site, and the cost is expensive.

3. The surface of the sprayed waterproof layer needs to be provided with another plastic isolation film to ensure that the expansion gap is reserved between the roof sprayed waterproof layer and the insulation layer, and the multi-channel construction is more cumbersome.

4. Due to the complicated construction process, the waterproof and thermal insulation requirements of the roof require a long construction period and high cost, especially the slope-finding layer that is directly compounded with the structural layer needs to wait for the final setting before proceeding to the next step of construction, which takes a long time. At the same time, the upper part of the slope-finding layer The multi-layer composite structure is constructed, and the layer load is heavy and easy to crack.

5. The waterproof layer is set in the middle of the roof structure layer. The leakage points on the surface of the structure are often not real leakage points, and cannot be accurately located. The structure layer needs to be substantially repaired. The construction is cumbersome and the workload is heavy.

6. The structure of the roof structure is complex, the construction level of the workers is uneven, and the construction technology is complicated. The slope layer, waterproof layer, insulation layer, and protective layer are all constructed separately. The cross-operation between different processes is easy to affect and damage each other. Different materials Due to the possible incompatibility between them, it is difficult to guarantee the construction quality and reliability, resulting in frequent quality problems or hidden dangers in buildings.
