One, what are the reasons why soundproof windows do not effectively block sound?
The primary factor determining the sound insulation performance of windows is the sound insulation performance of the glass and the sealing performance of the window frame. Both must be effective for the window to achieve optimal sound insulation.
1. First, glass
Currently available soundproof windows utilize either double-pane or hollow glass. The difference in glass type significantly impacts the soundproofing performance. Double-pane windows replace a single pane of glass with two, without any special sealing between the panes. This method only increases soundproofing through the addition of a single pane, resulting in subpar performance. True soundproofing is achieved with hollow glass. Hollow glass consists of two or more high-strength glass panes sealed with a sealant.
2. This also includes the airtightness of the window frames.
The sealing performance of window frames primarily depends on the profiles and sealing strips used in the window frames. Profiles with high calcium powder and raw material content are prone to cracking and deformation, which degrades sealing performance. High-quality aluminum alloy profiles for electric roller blinds are a durable and excellent choice. Single-chamber profiles are difficult to block noise transmission, while multi-chamber profiles increase the number of chambers, which further increases the barrier to noise transmission, thereby effectively blocking noise. Additionally, the sealing performance of windows significantly impacts sound insulation. Strong elasticity and weather-resistant sealing strips are essential for optimal sealing performance.
Two. What to do if soundproof windows are not effectively soundproof?
1、Apply window soundproofing film.
Acoustic membranes are a popular choice. When using acoustic membranes, the inner layer has visible light transmission properties, allowing light to pass through the building without obstructing visibility.
2、Install soundproof curtains.
A soundproof curtain is an inner frame beam installed on the top of the window frame, with a curtain box. Soundproof curtains are commonly used in enclosed spaces such as movie theaters, and they offer good soundproofing performance.
3、Install sound insulation and sealing strips
Acoustic sealing strips are specifically designed for windows with gaps. They are affordable, but it's important to determine if the lack of soundproofing is due to large window gaps. Otherwise, applying them will be ineffective.
