Sydney’s Strongest Sound Barrier Windows

Do you live in an area that requires sound barrier windows? Our aluminium sound barrier windows are a secondary glazing behind the primary window to provide impressive soundproofing. They are ideal for those living under flight paths, near busy roads, or in noisy industrial areas.

 Sound barrier windows make a remarkable difference to noise levels in your home or workplace and provide you with the peace & quiet you desire. No more noisy gardeners or loud neighbours to disturb your space. The Sound Transmission Class (STC) is the amount of noise reduced by a sound barrier window. If the levels outside are 60dB and inside it is 30dB, then the window is said to have a rating of 30 dB of STC. Remember that only a change in 10dB is heard, having only half of the original sound.

In addition, sound barrier windows help with insulating your space. Heat is better insulated by the secondary glazing layer. This is a great ancillary feature that many homeowners overlook. We have many options for these windows. Talk to us about colour and glass options today.
