The present invention uses metal materials with high surface density, PVC materials with light weight and good thermal insulation performance, and sound insulation materials such as damping sheets to form a wedge shape. Composite components are fixed on the structural layer of the exterior wall through slots and nails. It is easy to operate, stable and safe, and is suitable for installation of various window shapes; 3. The present invention is directly installed on the window without changing the traditional window installation method, which is easy to operate and does not increase the cost of the window itself. And it can greatly improve the service life of the window and improve the overall thermoacoustic performance of the window; 4. The present invention improves the surface density of the system through the sandwich structure composed of the first damping sheet, the steel plate and the second damping sheet, and at the same time the damping sheet Using it is like adding a small spring to the system, which can absorb the vibration caused by low-frequency noise to a certain extent; 5. After the installation is completed, compared with the traditional installation method, the visual effect only adds a slope, and the appearance is generous and beautiful.
