Triple Glazing Noise Reduction

Many people assume triple glazing’s rising popularity in the UK is due to the fact that it possesses tremendous heat loss reduction, helps the environment and can save hundreds of pounds each year in energy bills. These factors, of course, play a big part in rising sales; another big reason for the rise in interest is the triple glazing noise reduction benefits and to some people this is as much if not more of a reason to purchase this form of window.

Noise reduction

The rise in housing estates in the UK means that public transport must be widely available for easy access. Many people now live on bus routes, busy roads and near to railway stations or train tracks. Many estates now contain two or three schools, shops and community centres; all can be busy and noisy areas. Living close to a flight path and contending with the noise of numerous planes flying overhead is something that thousands of people will also be familiar with.

Contending with noise on a daily basis can affect well-being and health and can lead to an uncomfortable and sometimes miserable home life. Triple glazing noise reduction benefits can have a huge positive impact on people lives blocking out any unwanted noise from the outside world, the construction of triple glazing is what gives it the sound proofing properties.


There are three main elements to producing triple glazing noise reduction; the first is the glass that is used and more specifically the thickness of the glass. Each thickness of glass with help in blocking out a different noise frequency, a combination of three sheets of glass, each with a varying degree of thickness will play a very effective part in noise reduction. The name for triple glazing made in this way is asymmetrical glazing and along with the differing thicknesses, weight of the glass also plays a part, the compact mass of the glass can aid in blocking sound.

The second element the construction is the size of the gap between the sheets of glass. The larger the gap the better noise reducing capabilities, the extra sheet of glass that triple glazing has over double glazing means that it has an extra gap, two gaps equal more sound insulation.

The third element in triple glazing noise reduction is important, especially for people wanting triple glazing predominantly for sound insulating purposes. The use of an acoustical resistant gas to replace the inert gas that is usually inserted between gaps will effectively reflect noise away from the window; sulphur and hexafluoride are usually the gases that are used.

There are a few criteria that should be met in an effective sound proof window:

  • The window should contain no air ventilation as the window will be easily exposed to noise

  • Proper fitting and sealing of the window against surrounding wall will decrease the possibility of noise leaking through gaps between frame and wall

  • The window should be fully air tight
