How to choose the passive doors and Windows that meet the requirements (IV)
Pay attention to sound insulation performance.
Sound insulation effect of glass:
For environments with sound insulation requirements, the choice of glass is particularly important. Multi-layer insulating glass can effectively block the transmission of sound. For example, three-layer insulating glass combined with glass panes of different thicknesses (such as 5mm + 9mm + 5mm) can play a good role in blocking sounds of different frequencies.
The spacing distance between glasses will also affect the sound insulation effect. Generally speaking, the greater the spacing distance, the better the sound insulation performance. At the same time, the filled gas (such as argon) also helps to improve the sound insulation effect because the gas can absorb and reflect part of the sound.
Sound insulation ability of the overall structure of doors and windows:
The structure of the frame and sash of doors and windows will also affect sound insulation. Thick frame materials (such as broken bridge aluminum alloy) can reduce the conduction of sound. Moreover, the better the sealing structure of doors and windows, the higher the sound insulation performance. For example, doors and windows with an integrated sealing design can effectively reduce the transmission of sound from gaps into the room.
