What is Double Glazing?

If you’ve been browsing the cost of new double-glazed windows, you may be wondering whether they are worth the initial investment.

The best way of understanding how double-glazed windows can benefit your home is to understand exactly how they work.

It also helps if you know the exact benefits they bring and why these will save you money in the long-run.

How it works

Double-glazing, simply put, involves two panes of glass with a layer of gas in between. You may have been fooled into thinking that it’s just air in between the two layers; however it is actually argon gas (or potentially xenon or krypton).

The reason for this is that air, a combination of a number of gases, is actually quite a good conductive of heat. This means that it will pull the heat from your home outdoors through the layers.

Argon (or the other two elements), on the other hand, is not very good at conducting heat. This means it forms more of a useful barrier that will restrict the warm air escaping your house.

Noise reduction

If you currently have single-glazed windows installed, you may be all too aware of how noisy the outside world can be.

The combination of argon gas in between the two panes and the extra layer helps to keep the outside world truly outdoors. It seems like such a minimal addition to your windows, and yet it has such a profound effect on the peacefulness of your home.

You could be in the middle of the city and not notice a single thing going on outside, thanks to the double glazing.

Single-glazed windows are unfortunately some of the worst windows for letting out heat. There’s truly not much between you and the frosty outdoors when you have just one thin layer of glass in between.

This is what makes double-glazing one of the most energy-efficient ways of trapping heat inside of your home (on top of good quality insulation).


When it comes to break-ins, single-glazed is far easier to damage. You also have to take into consideration that it would be much louder to smash through double-paned windows.

The loud bang it could create would draw a lot of attention to the property. This stability and challenge to break through make them an ideal security solution for your home.

UV and condensation protection

If you have accidentally left a rack of CDs next to the windows over a long summer, you will know the effect that UV rays can have on coloured materials.

Double-glazing helps reduce the impact of these, protecting your furniture and belongings. On top of this, the two layers of glass help reduce condensation in the home.

Older double-glazed models and single-glazed panes can let in condensation into the home, causing mould and other issues that could not only have an effect on your paintwork and decoration but also your health.

Double-glazing isn’t a one-trick pony when it comes to its benefits. It’s an ideal solution for not only the warmth of your home but also its fundamental security and general comfort.
