One, the principle of silent doors and windows
1、The sound insulation performance of single-pane glass is primarily determined by the glass's density (the product of thickness and density). The glass densities available in the market are generally the same. Increasing sound insulation requires increasing the thickness of the glass.

2. The primary acoustic performance of double-layer hollow glass is determined by the actual thickness of the two glass layers and the distance between the two glass panes. All hollow glass structures exhibit standing wave resonance, which leads to a matching effect between specific frequency ranges and the hollow glass.
3. The sound insulation performance of laminated glass is primarily determined by the actual thickness of the glass, the thickness of the interlayer film, and the damping properties of the interlayer film. Better damping performance of the interlayer film results in improved overall sound insulation performance of the laminated glass (increasing by 1-3 dB). This is particularly important for sound insulation at medium and low frequencies.
Two. How long does it take to install a soundproof door and window system?
- Can be installed in 30 minutes to 1 hour, making it a quick process. Below, we will discuss the installation method for soundproof windows and important considerations:
1. If the existing window has been renovated, install a new window that looks identical to the original, effectively creating a double-window installation.
2、The window opening for sound insulation is located in the same place as the original window opening, ensuring future ventilation and air circulation.
3. If the original window is a swing window that opens outward, the installed soundproof window should also be a swing window that opens inward. If the original window is a sliding window, the width and size of the sliding window should be considered, and the opening width and size of the soundproof window should be determined based on the specific site conditions.
