If you live near an airport, highway, or playground, you may experience noise pollution in your home. Old, loose-fitting, single-pane windows that rattle when a plane goes overhead or a truck or train passes are probably the greatest source of noise transmission in a home since the windows are in every room.
Replacing your windows with ones that have a high Sound Transmission Class rating can help you reduce noise that enters from the outside of your home.
Sound Transmission Class (STC) is the main rating system used to indicate how well products block sound from entering the home. A typical dual pane window provides an STC rating of 26-32. A higher number means less sound is transmitted through the window. The combination of the glass layers, glass thickness and the air spaces between the glass give the windows the acoustical rating.
The key to blocking sound coming through a window is breaking up the sound wave vibrations. Sound can enter the home by vibrating the window or through cracks around the window or sashes. Specially designed windows with either offset glass (insulated glass units with glass of different thickness) or laminated glass can help reduce noise. Proper installation is also important to ensure noise is cut off around the window.
Sunrise has offered noise reduction windows for some time using laminated glass, which provides the added benefit of security glazing that keeps debris outside the home. The new NRG (Noise Reduction Glass) collection from Sunrise offers comparable noise reduction, at a fraction of the cost. The Sunrise NRG collection uses offset glass technology to break up sound waves and reduce noise entering your home.
