The sound insulation performance of aluminum single-panel curtain walls mainly depends on the following three aspects:
1.Good airtightness of the aluminum single panel itself
The airtightness of the aluminum single panel is directly related to its sound insulation performance. The quality of airtightness depends on the overall design of the product. If the sealing strips and joints of the aluminum single panel are not completely sealed, sound will be transmitted through the unsealed gaps, thus affecting the sound insulation performance. In addition, if the hardware accessories are not properly assembled, vibrations can easily occur in low-frequency environments, leading to product shaking or collision noises. For this reason, if you have such requirements, when purchasing products from aluminum single-panel manufacturers, you can request or inquire whether the manufacturer has a "sound insulation test certificate" issued by a professional certification body to ensure that the sound insulation effect of the purchased product meets the needs of your project.
2.Suitability of the thickness and specifications of the fluorocarbon aluminum single panel
Most aluminum single-panel curtain wall projects are large in scale, so the thickness and specifications of the aluminum panels will directly affect the sound insulation performance of the aluminum single-panel curtain wall. Generally, laminated fluorocarbon aluminum single panels have the best noise reduction properties, followed by hollow multi-layer fluorocarbon aluminum single panels, while single-layer fluorocarbon aluminum single panels have the worst sound insulation effect. Therefore, if you have high requirements for the sound insulation of aluminum panel curtain walls, we recommend using laminated fluorocarbon aluminum single panels when installing the curtain wall.
3.Construction quality during the installation of the aluminum single panel
Although some customers already understand the need for aluminum single-panel products to have a "sound insulation test certificate," if the inspection and adjustment of accessories (such as sealing strips and rollers) are not properly done during construction, it will also affect the sound insulation performance. Furthermore, if the "dry construction method" is used for aluminum single-panel installation, and the gap between the frame material and the old frame material is not properly filled with foaming agent, water droplets may hit the window frame, causing hollow echoes and even water leakage.
