Double glazing isn’t just a delicious donut topping — it makes windows better, too
They may sound self-explanatory, and in a way, they are — but double-glazed windows aren’t just about keeping hot or cold air in (or out, depending on the season). They also have other benefits. Here’s how they work.
Double-glazed windows are basically two pieces of glass separated by a gap of air that’s at least 12mm wide, filled with gas to increase the insulation between the panes of glass, then sealed. Compared to single-glazed windows, double glazing reduces heat loss or gain by up to 30% and reduces energy costs by more than 20%, making it a more sustainable, environmentally friendly choice for your home.
But that’s not all. Double-glazed windows also minimise the amount of outdoor noise that enters the home, which, unless you have no neighbours or street in front of your house, is always a bonus. They also reduce the amount of condensation that builds up on your windows, which helps prevent a build-up of moisture and the growth of mould. Perhaps most importantly for you, double-glazed windows increase the value of your property.
The bottom line? There are no downsides to double-glazed windows — either in the short or the long term.
