Learn About Sound Control at Gravina’s!
Sound control is greater when glass thickness increases. To increase sound resistance offset glass thicknesses on the thermo-pane. Most thermo-pane units have the same glass thickness unless specified otherwise.
To determine sound resistance, an STC (sound transmission class) rating is given. The higher the number is the better sound control. Typically replacement double and triple pane units have STC 30 or lower. To increase sound control, select STC 33 and higher.
