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.

卷簾門兩旁的中空玻璃由兩層或多層平板玻璃構成，四周用高強度氣密性好的復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 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.

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)設計要求加工成各種形狀吸音體

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

為了使卷簾門窗獲得理想的隔音效果，需注意以下幾點：

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

1、卷簾板閉合的密閉性;

1. The airtightness of the shutter closing;

2、導軌處的密閉性;

2. Airtightness of guide rail;

3、卷簾窗座條與窗臺的密閉性;

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

4、卷簾罩殼有足夠的緣性能，以避免產(chǎn)生單橋

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