Reduce Noise

Double glazing on all our product not only helps keep the Heat in and the Cold out but it can also reduce sound transmission by up to 80%.

Not only are there dramatic thermal benefits when using double glazing, the acoustic attenuation properties are improved. Generally, the windows are the weakest link in your building (aside from open building cracks, vents, etc) for allowing sound in. Sound travels in the form of a wave. As the sound waves pass through the glass, the frequency range changes, therefore attenuating the audible volume. The larger the space between the panes of glass, the higher the improvement of the noise insulation quality. Asymmetric double glazing, using different thicknesses of glass rather than the conventional symmetrical systems (equal glass thicknesses used for both panes) will improve the acoustic attenuation properties of the IGU. An Argon Gas fill will also improve acoustical attenuation performance. The most widely used glazing configurations for sound attenuation include laminated glass with a varied thickness of the interlayer laminate and thickness of the glass, argon gas fill and a single pane on the other side, differing in thickness from the glass used to make the laminated glass pane.
