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?

卷簾門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.

種：卷簾門兩旁的中空玻璃由兩層或多層平板玻璃構(gòu)成，四周用高強(qiáng)度氣密性好的復(fù)合黏劑將兩片或多片玻璃與鋁合金框或橡皮條黏合，密封玻璃之間留出空間，充入惰性氣體以獲取優(yōu)良的隔熱隔音性能。由于玻璃間內(nèi)封存的空氣或氣體傳熱性能差，因而產(chǎn)生優(yōu)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.

第二種：夾層玻璃是指在兩片或多片玻璃之間夾上PVB中間膜。PVB中間膜能減少穿透玻璃的噪音數(shù)量，降低噪音分貝，達(dá)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.

第三種：卷簾門中的吸音裝飾板是新型建材，具有優(yōu)異的吸音性能并有阻燃防火作用。一般都備有多種顏色及圖案裝飾布可供選擇，有些產(chǎn)品還可根據(jù)設(shè)計要求加工成各種形狀吸音體。

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.
