Rolling shutter door is a kind of door and window that we use every day. It has a wide range of uses, especially in the garage and warehouse. We have already talked about the material selection of rolling shutter door. Now, let's talk about the sound insulation effect of rolling shutter door?

卷帘门隔音材料可起到降低噪音、隔音扽效果。

Rolling shutter door sound insulation material can reduce noise and sound insulation effect.

种：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 first kind: the insulating glass on both sides of the rolling shutter door is composed of two or more layers of flat glass, and the two or more pieces of glass are bonded with aluminum alloy frame or rubber strip with high strength and good air tightness around. Space is reserved between the sealing glass and inert gas is filled to obtain excellent heat insulation 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.

第二种：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。

The second kind: laminated glass refers to the PVB intermediate film sandwiched between two or more pieces of glass. PVB membrane can reduce the amount of noise penetrating the glass, reduce the noise decibels, and achieve sound insulation effect.

第三种：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 third kind: the sound-absorbing decorative panel in the rolling shutter door is a new type of building material, which has excellent sound absorption performance and fire-retardant effect. Generally, there are many kinds of color and pattern decorative cloth to choose from, and some products can be processed into various shapes according to the design requirements.
