NOISE REDUCTION

Double Glazing can significantly reduce noise entering through windows

The use of a Double Window System can reduce noise by over 75% when compared to ordinary 3mm single glass.

The use of sealed double glazed units (IGUs) can reduce noise by over 55% when compared to ordinary 3mm single glass.

DOUBLE WINDOW SYSTEM (for existing aluminium windows)

As can be seen in the above table the Double Window System is by far the most effective way to reduce noise entering through windows. This is due to the fact that the bigger the gap between the glass panels then the greater is the sound reduction. A difference in glass thickness between the inner and outer panels also benefits sound reduction.

Our Double Window System uses 6.38mm thick laminated glass in conjunction with relatively thin glass in the existing aluminium window.

The Double Window System is ideally suited to reducing traffic noise. It can be adapted to most existing aluminium windows.

The Double Window System is installed internally and is barely perceptible from the outside. Therefore it is the ideal solution for noise control in flats, units and other higher density dwellings where body corporates may have controls on the external appearance of buildings.

Apart from the noise reduction benefits there are also the thermal insulation benefits associated with double glazing.

SEALED DOUBLE GLAZED UNITS (for existing timber windows)

Although not offering the very high sound reduction of double windows, sealed double glazed units (or insulated glass units- IGUs) still provide very good sound proofing together with excellent thermal insulation. They can be configured with different glass types to provide optimum sound reduction.

They are suitable for fitting into most new and existing timber windows.
