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 fully closed rolling shutter window installed outside the glass window. Through the research, it is found that the larger the distance between the rolling door manufacturer and the glass window, the better the noise reduction effect. The closed rolling window itself can reduce the noise of 18db. If it is combined with the insulating glass window (4 / 12 / 4mm), the comprehensive sound insulation effect of 37db can be obtained.

卷帘门两旁的中空玻璃由两层或多层平板玻璃构成，四周用高强度气密性好的复合黏剂将两片或多片玻璃与铝合金框或橡皮条黏合，密封玻璃之间留出空间，充入惰性气体以获取优良的隔热隔音性能。由于玻璃间内封存的空气或气体传热性能差，因而产生优越的隔音效果。

The insulating glass on both sides of the rolling shutter door is composed of two or more layers of flat glass. Around the door, two or more pieces of glass are bonded with aluminum alloy frame or rubber strip with high strength and good air tightness composite adhesive. The space between the sealing glass is reserved and filled with inert gas to obtain excellent heat and sound insulation performance. Due to the poor heat transfer performance of the air or gas sealed in the glass room, the superior sound insulation effect is produced.

夹层玻璃是指在两片或多片玻璃之间夹上PVB中间膜。PVB中间膜能减少穿透玻璃的噪音数量，降低噪音分贝，达到隔音效果。

Laminated glass refers to the PVB intermediate film sandwiched between two or more pieces of glass. PVB intermediate film can reduce the amount of noise penetrating the glass, reduce the noise dB, and achieve the sound insulation effect.

卷帘门中的吸音装饰板是新型建材，具有优异的吸音性能并有阻燃防火作用。一般都备有多种颜色及图案装饰布可供选择，有些产品还可根据设计要求加工成各种形状吸音体

The sound-absorbing decorative board in rolling shutter door is a new type of building material, which has excellent sound-absorbing performance and fire-retardant function. Generally, there are a variety of colors and patterns to choose from. Some products can also be processed into various shapes of sound absorbers according to the design requirements

为了使卷帘门窗获得理想的隔音效果，需注意以下几点：

In order to achieve the ideal sound insulation effect of rolling shutter doors and windows, the following points should be paid attention to:

1、卷帘板闭合的密闭性;

1. The airtightness of the shutter closing;

2、导轨处的密闭性;

2. Airtightness of guide rail;

3、卷帘窗座条与窗台的密闭性;

3. The airtightness of the roll up window base strip and the window sill;

4、卷帘罩壳有足够的缘性能，以避免产生单桥

4. The rolling shutter shell has enough edge performance to avoid single bridge
