Noise is an ever-growing concern in today’s world. High traffic streets and noisy factories are issues that people must face ever more often. Using insulated glazing for sound damping can be an effective solution. Depending on their purpose, insulated glass units have different product properties for achieving the desired sound insulation performance. The acoustic attenuation capacity of an IGU depends on different factors.
Laminated glass can be selected with a thin acoustic film, which also offers protection against the fading effects of UV rays. SILENCE film offers new ways to dampen noise, and works effectively in different noise environments. The first thing to remember about noise attenuation is that a structure is only as attenuating as the weakest part of it. In other words, there is no point in having a good sound-absorbing glass package if the frame does not prevent noise transmission. The noise insulation properties of a glass package can be improved by increasing the thickness of the glass, increasing the air gap between panes and using laminated glass.
The table presents IGUs of different structure. The higher the sound reduction index, the more efficiently an IGU can damp sound. As seen, IGUs with panes of different thicknesses are better sound insulators than IGUs with panes of the same thickness.
