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(dǎo)軌處的密閉性；

2. Tightness of guide rail;

3、卷簾窗座條與窗臺(tái)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(chǎn)生單橋。

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

卷簾門遇障礙自動(dòng)彈回來(lái)的人性化設(shè)計(jì)，防止門體下落運(yùn)行時(shí)對(duì)車物的碰撞，使人或車輛順利通過(guò)。門體堅(jiān)固，且可配有和防上推裝置，防止以強(qiáng)制手段撬動(dòng)門體，持續(xù)報(bào)警，安 全防盜。

The humanized design that the rolling shutter automatically bounces back in case of obstacles prevents the collision of the door body with the vehicle during falling operation, so that people or vehicles can pass smoothly. The door body is firm, and can be equipped with and anti push-up device to prevent prying the door body by forced means, continuous alarm and security.
