Usually, people want to have a quiet room, especially the room close to the street and highway. The sound insulation effect of the window can be greatly improved by using the fully closed rolling shutter window installed outside the glass window. Through research, it is found that the larger the distance between rolling shutter window and glass window, the better the noise reduction effect. The closed rolling shutter window itself can reduce the noise of 18db. If it is combined with the thermal insulation glass window, it can obtain a comprehensive sound insulation effect of 37db. In order to achieve the ideal sound insulation effect of rolling shutter doors and windows, the following points should be paid attention to:

1、卷簾門閉合的密閉性；

1. Airtightness of rolling shutter door closing;

2、導軌處的密閉性；

2. Tightness of guide rail;

3、卷簾窗座條與窗臺的密閉性；

3. Airtightness between roller shutter window seat strip and window sill;

4、卷簾罩殼有足夠的絕緣性能，以避免產生單橋。

4. The roller shutter housing has sufficient insulation performance to avoid single bridge.
