Usually, people want to have a quiet room, especially near the street and road. The sound insulation effect of the window can be greatly improved by using the completely closed rolling shutter window installed outside the glass window. It is found that the larger the distance between the rolling shutter and the glass window, the better the noise reduction effect. The closed rolling shutter window can reduce the noise by 18db. If it is combined with insulating glass window (4 / 12 / 4mm), it can obtain a comprehensive sound insulation effect of 37db.
In order to obtain ideal sound insulation effect of rolling shutter doors and windows, the following points should be paid attention to:
1. The closure tightness of rolling shutter plate;
2. Airtightness at the guide rail;
3. The airtightness between the shutter seat and the sill;
4. The roller shutter cover has enough insulation to avoid single bridge.
