One, Why the sound insulation effect of windows decreases after long-term use
Over time, the soundproofing performance of soundproof windows can deteriorate. This may be due to the initial poor quality of the windows themselves. When newly installed, soundproof windows have fresh sealing materials that provide excellent soundproofing. However, as we use them, these sealing materials gradually degrade and lose their sealing function, resulting in the soundproof windows no longer providing effective soundproofing.
Additionally, if the installation method for the soundproof windows is incorrect, it can also lead to problems with the window frame, causing the windows to gradually lose their soundproofing effectiveness.
Two. If the soundproof windows are no longer soundproof, how to handle it.
1、Apply window soundproofing film
Acoustic membranes are currently very popular. When using acoustic membranes, the inner layer has visible light transmission properties, ensuring that the building's visibility is not obstructed and maintains clear sightlines.
2、Install sound-absorbing curtains
A soundproof curtain is a type of window covering that consists of an inner frame with a curtain box installed at the top of the window frame. Soundproof curtains are often used in enclosed spaces, such as movie theaters, and they provide effective sound insulation.
3、Install sound insulation and sealing strips
Applying soundproofing seals to the gaps between window frames in soundproof windows can also effectively mitigate the gradual loss of soundproofing performance.
4、Replace existing windows with new soundproof windows.
The methods mentioned above are only addressing the symptoms and not the root cause. They cannot effectively solve the problem of sound transmission through windows. To achieve a permanent solution, it is necessary to replace the poorly manufactured or improperly installed windows with high-quality windows, and to supervise the installation process to ensure that the new windows are properly installed.
