Soundproofing Windows 101

People living in both city and suburban environments are subjected to a variety of noises from the outside. Windows are the most common way for annoying noise to penetrate into the living and working areas.

Primary (exterior windows) with thicker double-paned glass can reduce noise somewhat, but the best solution is to complement your existing window with a soundproof interior window to create a sound buffer zone which can reduce noise by up to 95%.

As you’ll see from the illustration below, the Cityproof window is an internal window that is placed in front of the existing exterior window. The air space is beneficial to noise reduction because the air trapped inside acts as a damper to sound passing through your windows. Additionally, Cityproof state-of-the-art windows include laminated glass with a special PVB Polyvinyl butyral (or PVB) is a resin that reduces noise passthru, increases glass safety, and provides 99% UV protection. interlayer sandwiched between the glass layers that helps reduce low and high frequency noises from passing through the windows.

For further reading, our glass partner, Saflex, has created a comprehensive overview of acoustical glass performance. Pages 19-23 in the Saflex Acoustical Guide illustrate solutions like the Cityproof system that include interior laminated windows featuring a PVB layer, an air space, and an existing exterior window.

Here's How Our Advanced Soundproofing Interior Window System Works:

Internal Installation

The Citiwindow® is an internal window installed on the inside of an existing window. The exterior window remains as is.

Sound Buffer Zone

The airspace created between the exterior window and the Citiwindow acts as a sound buffer zone, which also eliminates draft & dirt infiltration and provides maximum thermal control.

A Perfect Seal

Our unique tracking systems provides a perfect window seal. And a perfect window seal means up to 95% less noise for you!
