Poor sound insulation performance

The noise problem is not as good as relying on yourself. The noise problem must be solved first. Energy-saving doors and windows can effectively reduce noise. To enter the room, noise must first pass through four barriers of energy-saving doors and windows, and each barrier will reduce the first-class noise. The first barrier: the outer layer of automobile grade float glass; The second barrier: hollow high-purity inert gas argon; The third barrier: the hollow distance of 12mm and 16mm; The fourth barrier: the original plate of automobile grade float glass, the inner layer of which is coated with temperature screen film.
