Double or triple glazing for noise reduction?

Dealing with excessive noise in your home and wondering whether to opt for double or triple glazing for noise reduction?

If you live on a flight path, next to a busy road or in a city centre, noise pollution is likely to be a major issue. Or perhaps you have to live with noisy neighbours and put up with their choice of music in the early hours of the morning. Dealing with excessive noise can have a big impact on our wellbeing and quality of life, leading to broken sleep and rising stress levels.

Once you get home after a long day at work, most of us want to shut the front door and enjoy a peaceful haven from the hustle and bustle of daily life. If excessive noise is stopping this from happening, then soundproofing your home is an investment worth making. Read on for our helpful tips about how to choose the best sound-proofing solution for your home.

Should I choose triple glazing for noise reduction?

Triple glazing is a popular option in colder countries and works by adding an additional pane of glass to the unit. People often assume that triple glazing would be the better option for noise reduction as the extra glass of pane will reduce the sound levels – but in reality, that isn’t the case, particularly if the triple glazing panes are all the same thickness.

When it comes to sound insulation, the additional cost of triple glazing often outweighs the benefits based on noise reduction alone.

Whilst triple glazing isn't necessarily the best choice for noise reduction, there are other major benefits which are vital to consider when choosing your windows:

  • They deliver a fantastic thermal performance for your home. uPVC windows are a great example of bespoke windows that reduce energy bills and keep your home warm and cosy. These windows are available in either double or triple glazing and provide a flexible choice.
  • Triple glazed units also provide increased home security than double glazed windows, which is always an added reassurance.

How does double glazing reduce noise levels?

If your home has badly fitted single glazed windows, there’s likely to be very little sound-proofing. Replacing with double glazed windows can make a big difference. When choosing your replacement windows, the important points to look out for are the thickness of the glass and the gap between the panes. It’s well worth looking for double glazed windows where one pane is 33% thicker than the other.

The different thicknesses will alter the sound wave as it comes through the double glazing unit, reducing the noise levels in your home. Choosing one soundproof laminate pane in the unit also reduces noise even more, as the laminate glass actually contains two pieces of glass as well as an interlayer.

So which is the most effective solution?

It’s clear that double and triple glazing both have their strong points. But looking at noise reduction alone, here’s our verdict:

Opting for double glazed windows that have a gap between the panes, different thickness of glass and a laminate glass pane could achieve better results than triple glazing and will save you money, too.

When making your decision, weigh up how important noise reduction is compared to thermal insulation or home security. It’s no good sound-proofing your home and then having to deal with energy bills that go through the roof or a home that’s always chilly. It may be worth considering triple glazing for noise reduction if you also need to improve the energy efficiency or security of your home. But if your number one priority is to escape from noisy neighbours, then go for double glazing and enjoy the added peace!
