Acousta™ Laminated glass uses a specially formulated interlayer which is very effective in reducing noise.
Solutions for noise reduction
Glass is just one of many components in a building and the noise reduction values presented are for glass only. Window and door manufacturers test their products as a whole component – window frame and glass combined. It is best to consult the window supplier for this information. Other points that should also be considered are the frequency and intensity of the sound, building construction and materials, noise corridor regulations and any specialised acoustic requirements.
As a general rule, increasing mass will improve sound insulation. Materials such as brick and concrete have stronger sound insulating values when compared to glass, but then, unlike glass, you can’t see through them. To provide natural daylight and to enhance a buildings look and appeal, the need for greater sound control when using glass becomes important. Acousta™ Laminated glass uses a specially formulated interlayer which is very effective in reducing noise.
The table below shows a single number Rw rating of sound reduction measured in decibels (dB). The bigger the number the greater the sound reduction. Typically most standard residential buildings are glazed in a 4mm single glass thickness or 4/12/4 double glazed thickness. Acousta™products below show a 10dB improvement in sound reduction and to put this into perspective, the human ear will perceive this as a 50% reduction of the noise intensity.
