How to change the fixed glass of the curtain wall to open the window to reduce the sound?

Are you looking for windows that can reduce noise transmission? Start with the noise level. High-noise windows can better reduce noise. Why the higher the noise level, the louder the window sound? There are many factors that affect the sound insulation of windows, including material, glass thickness, glass type and spacing. The highest rated noise window combines all these factors to 'sound' the office, which usually means a 90% to 95% reduction in external noise.

The following are some factors and materials for changing the fixed glass of the curtain wall to the window, which can maximize the sound insulation effect of the fixed glass of the curtain wall to the window: Glass thickness-The thickness of the glass is the most critical factor affecting the noise level of the window. Thicker glass eliminates more sound. Therefore, windows with higher noise tend to use thicker glass. Laminated glass-Laminated glass has become the standard in high-risk areas due to its high impact resistance. But it also helps to increase noise levels. Laminated glass windows have a layer of plastic sandwiched between two layers of glass. The plastic layer helps reduce noise, and because of its design, the glass is usually thicker. Spacing-Most commercial replacement windows are double glazing, which means there are two layers of glazing. The spacing between each piece of glass has a certain effect on reducing noise. Wide spacing helps attenuate sound waves. In addition, the inflation between the panes helps to slow down the spread of sound. Adding another layer of glass will increase the sound control capabilities of the windows, which seems correct. Three-pane windows generally have better performance than two-pane windows. A three-pane window often has a small space between each pane. Air separation is a necessary condition for sound absorption. Generally speaking, the larger the gap between the glass, the better the window can eliminate noise. On the other hand, dual-pane windows maximize the noise reduction space between the panes, so they generally perform well in noise reduction. Installing windows with higher noise levels is the first step in reducing noise transmission. Replacing an existing window can be more expensive, and you can perform some steps before replacing the window (in some cases, after the replacement). They include: Repairing car window seals: Existing window frames may not be completely sealed, which is the main cause of noise transmission. Repairing gaps and leaks helps reduce noise and airflow, which is a more cost-effective solution than complete replacement. This is the first step you should take, but it is usually difficult for property managers to make one on every window of their building.
