How to choose doors and windows for better noise prevention?

The noisy city brings us all kinds of happiness, so we miss it, but we can't sleep peacefully all night, which will definitely make many friends feel annoyed, especially living in a neighborhood or apartment near the road, which is very annoying. The sound of cars coming and going makes people unable to sleep peacefully, so how can we ensure the sound insulation of windows? Old carpenter Luban doors and windows come to study with you!

Selected window frame

Nowadays, window frames are generally made of aluminum-magnesium alloy, but aluminum alloy profiles are all single-cavity, relatively thin, and sound is very easy to penetrate. However, plastic-steel profiles are multi-cavity and thicker than aluminum profiles, and the actual sound insulation effect is also very good.

Sound insulation laminated glass

Sound insulation laminated glass includes hollow glass window, vacuum glass and laminated glass, among which laminated glass and vacuum glass are widely used. If the building at home is higher than 20 stories and there are no large and medium-sized cars around, you can choose to apply laminated glass and hollow glass windows, and the actual sound insulation effect is not bad. Vacuum glass is the basic principle that vacuum pump can't transmit sound, and it can cope with all kinds of noise. After installation, the noise can be reduced by 30 to 40 decibels. If there is a low-frequency noise source in the building near the overpass or nearby, you can consider applying composite three-layer sound insulation laminated glass or vacuum glass, which can completely deal with the noise problem.

Use soundproof strips

Aluminum alloy profile window frames generally use plastic soundproof strips or material soundproof strips. However, the plastic is very easy to harden and age after being used for a long time, and the material sound insulation strip is very easy to lose hair after being used for a long time. Therefore, the window soundproof strip must maintain ductility and aging resistance. At present, there is an imported soundproof strip on the market, which is made of silencing cotton inside and encapsulated by leather material outside, which not only controls the ductility but also is not easy to age, and well ensures the sealing performance of the sound leakage point of the window frame.

Install soundproof windows

Another thing is that we can install soundproof windows right away. At present, two layers of hollow windows are generally used for sound insulation, which can block traffic noise. If we think it is not good to add a layer of soundproof window in our home for natural ventilation, we can tear down the original window and replace it with a low-frequency soundproof window.

Do a good job of sealing

When installing the window, there will be some small gaps around the window, so be sure to glue it with the structure. If you want to do it well, you must ask professional technicians to complete the actual operation.
