Material selection of window frame. At present, aluminum alloy is widely used. Aluminum alloys are all single-cavity, with thin walls and easy sound penetration. In contrast, the multi-cavity and wall of plastic steel profile are thicker than that of aluminum alloy. Sound is unlikely to penetrate the outline.

Selection of sound insulation strip. Generally, most aluminum alloy window frames are equipped with rubber soundproof strips or wool soundproof strips, but the wool soundproof strips are easy to fall off after being used for a long time, and the rubber has become hard and aging after being used for a long time. Therefore, the sound insulation strip should not only prevent aging, but also maintain toughness. There is an imported soundproof strip on the market at present. The outside is wrapped in leather material. It is made of sound-absorbing cotton. In this way, the toughness is maintained and it is not easy to age. The sealing of the sound leakage point of the window frame is well guaranteed.

The most important thing is sound insulation glass's choice. Now there are mainly insulating glass, laminated glass and vacuum glass on the market. The first two prices range from 100 to 78 100. One or two hundred glasses, I won't say much. The sound insulation effect of street stalls can not be guaranteed. A company specializing in soundproof doors and windows. Mostly laminated glass and vacuum glass. Vacuum glass uses the principle that vacuum can't conduct sound, aiming at noise of various frequencies. After installation, the noise can be reduced by 30-40 decibels. Sound insulation glass's Choice Chuangxin suggested that everyone should look at the actual situation of their home and the environment of the community. For example, if the floor is higher than 20 floors and there are no trains or large trailers nearby, you can consider choosing insulating glass or laminated glass, and the sound insulation effect is similar. If the floor is low, close to the road or viaduct, and there are low-frequency noise sources nearby, then you should consider using vacuum glass or composite three-layer sound insulation glass, so as to completely solve the noise problem.

Seal the surrounding frame after installation. When making soundproof windows, be sure not to make them as big as the windows. So I can't put it in. So there will be some small gaps around the window frame. So after installation, be sure to stick the windows around with glass glue. The sealing around seems simple, but it still needs professionals to complete it perfectly.
