Double pane windows with dissimilar glass (where the two panes of glass are different thicknesses) can have even higher ratings; around 34. Sound Insulation To understand if your triple glazing windows are sound reducing you need to look at the Sound Transmission Class (STC) rating which is measured in decibels (db). If With increases of air space, figures greater than 50 are easily achieved. some basic principles to remember that can help improve the STC ratings A windows STC rating indicates how much sound waves are reduced. Soundproof, double pane Windows have a higher STC rating the thicker they get. Consider that an average exterior wall of a stick-built home has an STC rating between 34 and 38. Anything higher is impractical because, while sound might not enter via the windows, it will just as easily enter through the lower-performing exterior walls. The most common locations of air penetration are around the Soundproof Windows range from 48 to 54 (with more possible), which varies depending on the existing window and the air space. the perimeter. The first measure of acoustic performance is referred to as the Figure 1. For builders, contractors and architects alike, sound control is an The higher the rating, the better the sound control. STC ratings are the ONLY way to accurately compare various noise reduction products. Triple-glazed windows, such as our Stormsure Energy+ window, can achieve incredible STC ratings of 40 or higher.
