Three kinds of sound-proof glass to help isolating outdoor noise
1. Insulating glass
At present, most doors and windows choose to use insulating glass for sound insulation. Two or more pieces of glass are bonded to form a dry gas space in the middle, which plays the role of sound insulation and heat insulation. At the same time, it can also improve performance in many aspects through operations such as tempering and coating. More popular on the Internet.
However, the hollow glass is more obvious to medium and high frequency noise, such as human voice, horn sound, etc., and it has a general effect on low frequency traffic noise (train, airplane, engine).
2. Vacuum glass
Vacuum glass is similar to insulating glass, but the vacuum glass between the two layers of glass is close to the vacuum environment. Under the vacuum environment, heat and sound can not be transmitted, so the sound insulation and thermal insulation performance are very good. It is a superstar in the glass industry. Isolate all noise, but the effect is very good.
However, vacuum glass has not been popularized, and once a gas enters the vacuum layer of the glass, its performance and life will be affected. Therefore, it needs to be carefully maintained during use.
3. Laminated glass
Laminated glass is generally composed of two layers of glass and film, which can block traffic noise at low and medium frequencies. It is often used for sound insulation glass on busy roads, but it is not very suitable for doors and windows because laminated glass is relatively heavy. In terms of building door and window standards, door and window hardware that uses laminated glass is more likely to break.
When choosing which kind of soundproof glass to use, you can make a decision based on the size of the soundproof area and the height of the floor. Generally, the smaller the window area and the higher the floor, the easier the sound insulation and noise reduction will be.
