Cancel out the Noise with Double Glazing


Taxi in motion in LondonNoise pollution is a real problem for many homeowners with noisy neighbours, nightlife and the biggest bugbear, busy roads. Particularly if you are raising a young family or working during unsocial hours, getting proper rest without the worry of noise is paramount.

Thanks to advances with technology, getting access to noise-cancelling windows is very affordable and makes all the difference. Take a look here to find out how double glazing can be a solution for your noisy home and other ways to keep the noise out.

Soundproof Windows – What’s the Science?

Unlike walls and ceilings, which block and absorb sound waves, windows allow more vibrations to travel through and enter the house. From there it is all down to acoustics – some noises will travel through better than others.

There are a couple of ways to get rid of this unwanted sound:

  • Create a larger gap between the window panes. The more air that is between them then the more sound can be absorbed, therefore stopping the vibrations from getting into the house. See the paragraph ‘What is double glazing’ to see this explained more.
  • Add mass to the glass and make it thicker -this one’s simple. By making the actual panes of glass thicker, the sound waves will not be able to travel past the window in the first place, keeping it on the outside.

What is Double Glazing?

Double glazing (or is also sometimes known as insulating glass) consists of two panes of window panes separated by a vacuum or a gas filled space. The thickness of the glass and the distance between the two panes can be altered as needed.

This kind of window comes with a whole host of benefits for your home including sound insulation, safety, thermal performance, better durability and many more. Another perk is that it doesn’t require any planning permission so almost every house can have it installed.

Sound Proofing with Double Glazing

If you’re planning on moving from single glazed windows to double glazed, you may be surprised by the sound difference. Generally the larger the gap between the two window panes, the better sound insulation you will receive. This is something you can talk to us about and we will be able to recommend you with the best window for your area and budget.

One thing to think about if you live in a particular noisy area, for example by an airport, is purchasing double glazed windows where one pain is thicker than the other which will alter the sound wave as it tries to come through.

What about Triple Glazing?

Triple glazing is very similar to double glazing however there are three panes of glass with gas in between them. Logic would tell us that triple glazing would offer the benefits of double glazing and more but this isn’t always the case due to the way sound travels. Noise insulating is down to the thickness of the glass and the size of the gap, not just the number of windows.

Triple glazing does come with many advantages such as being energy efficient, safer and more durable. However, when it comes to noise reduction, they are both just as good as each other.

Arguably, it does cancel out noise in a similar way to double glazing; if the glass is thick and the gaps are big then it will break down the sound waves and stop it from entering the home. It’s all really down to size.

Sound Proofing with Secondary Glazing

Secondary glazing is much less heard of, however it is an amazing option for those who want a non-permanent fix and don’t have the budget to renew all the windows in the house.

It involves installing supplementary glazing on the inside of an existing single-glazed window. It can be put in as a permanent piece or a temporary fix.

When it comes to noise reduction, secondary glazing is the gold medal winner. Unlike double glazing, secondary glazing means the two panes of glass sit as independent barriers. This will make the gap between the windows larger and the sound waves will be damped a lot more.
