How to choose a good soundproof window?


The noise of the city has a great impact on our daily life. It not only affects our sleep during work and rest time, but also affects our physical health for a long time.

If you want to deal with outdoor noise pollution, the role of doors and windows is very important! So how to choose soundproof doors and windows? Mainly depends on three factors.

1. Glass

The core of soundproof doors and windows is glass, such as insulating glass and laminated glass, which are good soundproof glass.

But before choosing glass, you must first determine what the source of external noise is in your home and make targeted choices.

Laminated glass has a good noise reduction effect on medium and low frequency noise, such as people's walking, talking and so on.

The sound of cars and motorcycles is high-frequency noise. If it is close to the roadside community, then choosing insulating glass can have a better sound insulation effect.

2. Profiles

Different profiles have different sound insulation effects. Relatively speaking, ordinary aluminum alloy is a relatively thin single cavity, and the sound is easy to penetrate.

The broken bridge aluminum doors and windows + insulating glass can achieve effective sound insulation, because the cavity structure of the broken bridge aluminum alloy can effectively reduce the resonance effect of sound waves and prevent sound transmission.

Taking broken bridge aluminum as an example, the thermal insulation structure design of the five-chamber double-broken bridge, coupled with the use of hollow tempered glass, greatly improves the sound insulation effect, which is very suitable for residents with low floors, close to roads or viaducts.

3. Sealing performance

The main factors affecting the sealing performance are the rubber strip and the opening method.

The sealing strip not only improves the sound insulation performance of doors and windows, but also plays an important role in the overall thermal insulation of doors and windows and reducing energy consumption.

Therefore, it is necessary to choose automotive-grade sealants with good resilience, soft and hard co-extrusion, and good aging resistance.

Regarding the opening method, casement windows are better than sliding windows.

When the sliding window is closed, the two sashes are not on the same plane, resulting in no sealing pressure and convection, so the sealing performance is poor.

The casement type window has a much better bite force, strong airtightness, and better sound insulation.
