[0002] Common soundproof windows currently on the market generally utilize a single frame structure, securely fastened to the window opening via various hardware. To achieve excellent sound insulation, designers meticulously install multiple layers of glass within the frame, hoping this multi-layered structure effectively blocks incoming noise. However, in practice, to ensure overall structural stability and safety, this multi-layered glass design necessitates a corresponding increase in the frame's size and thickness, improving its overall load-bearing capacity and strength.
