Sound Proofing - Double / Triple Glazing or Secondary Glazing?

Noise intrusion into the home is a common problem if you live close to busy roads, railway lines, under flight paths or near industrial units in Andover and Hampshire areas, as windows tend to be the weakest point of sound insulation in the home.

Unlike walls and ceilings, which block and absorb sound waves, windows (glass) allow more sound vibrations to pass through and enter the home. The most common and invasive noises are high-frequency sounds, so how do we reduce this and increase the sound proofing of your glazing? They are the perfect solution for homes looking for much needed peace.

Soundproofing with Double Glazing

Double glazing does provide sound proofing, especially if it’s replacing existing ill-fitting single glazed windows. Generally the larger the gap between the panes, the better the sound insulation. This can be enhanced where one pane of glass is thicker than the other, such as 6mm glass one side and 4mm the other. This acts as a better sound barrier than normal sealed units, because the different thickness of glass changes the sound wave as it travels through the unit.

Another option is to use 6.4mm laminate glass to the outside of your glazing to offer additional sound proofing. This is also much more secure as laminated glass can not be penetrated as it houses 0.4mm perspex between the two 3.0mm panes of glass. This type of glass is similar to what is used in car windscreens today. There is also available a range of acoustic glass options, one of the most popular is Stadip acoustic glass the standard panel for most glazing is 6.8mm thick.

It is worth remembering that the use of trickle ventilators within a window can destroy the acoustic performance of new windows. When noise is a major problem, special acoustic ventilators are necessary, however, the downside of these items are they are large and unsightly

Soundproof Windows - What's the science?

The best type of sound proofing is secondary glazing as the gap between both panels is far greater than conventional double glazing. Many households around airports are fitted with secondary glazing to help with noise reduction.

If you live on a main road with traffic noise, secondary glazing is a great way to reduce further noise as you can also benefit from the different thickness of glass from that of the primary window. The optimum gap to reduce heat loss and keeping external noise to a minimum is between 100mm-150mm between the secondary glazed unit and your existing window (glass to glass). However, this would normally mean that little or none of the internal cill would be left.

Changing the thickness of the glass between your existing window and your new secondary glazing will change the frequencies of the sound wave length and reduce noise further. i.e. Existing window glass 4mm – install secondary glass 6mm.  Ordinary glass at 4mm thick will significantly reduce noise, however if noise reduction is paramount then we would recommend our 6.4mm laminated or 6.8mm Acoustic ‘Stadip’ glass. These glasses can reduce external noise by as much as 75 – 80%.

Adding an extra pane of glass with our triple glazing will only provide a small increase in sound insulation, if all three panes are of the same thickness. Specifying one different pane thickness will increase sound insulation.
