How to select soundproof door and window materials？
Double-layer vacuum glass has good sound insulation, which is warm in winter and cool in summer. Its characteristics are that the glass is made of a hollow flat box with six sides of glass, and the hollow is in a vacuum. The hollow flat box has a glass support column in it. This kind of glass can insulate the noise, reduce the interference of various noises in the city, keep warm in winter, and insulate in summer, creating a quiet and comfortable life for people, The usual way to work in the environment is to remove the air in the middle of the glass### 1. The insulating glass has good sound insulation effect. Insulated glass is widely recognized for its superior performance in heat insulation, sound insulation, sealing, frost prevention, dust prevention, etc Insulated glass is used to seal two or more glass edges together, form static dry gas between the glass, and have certain vacuum performance. Its main materials are aluminum spacer strip, corner bolt, butyl rubber, polysulfide rubber, and desiccant Features of insulating glass: A. Thermal insulation performance: the coefficient of heat transfer k is less than 3.0kw/mm.k. B. Sound insulation performance: but the external noise transmission is reduced by 27-53 dB C. Frost resistance: the glass can reach - 40 ℃ D. Sealing performance: not easy to enter dust
