Combining two different thicknesses of glass in a double-glazed unit can have a beneficial effect on reducing sound. Although we cannot assess the level of noise within your property, we have tested different combinations of this guide to assess the reduction of sound that our products will achieve.   

Triple glazing offers little advantage in terms of acoustic performance as the nature of most triple glazing constructions limits the options of glass choice. In most cases adequate performance can be achieved with double glazing.  

For optimum noise reduction, Pilkington Optiphon™ is a laminated product, which has a special acoustic PVB interlayer. Available in a number of different thickness from 6.8 mm to 16.8 mm, this product can be combined with other products in double glazed units to achieve excellent sound reduction. Please contact a local installer for availability and advice.
