Back to basics: What is double glazing?

Double glazing is the most popular form of glazing in the UK but do you actually know what it is and how it works? Here’s a brief guide on everything you want to know about double glazed windows.

How does double glazing work?

As the name suggests, double glazing consists of two panes of glass with an air or gas filled space between them. The space in between the glass panes traps heat; the cold can’t come in and your warmth can’t leave. Also, unlike single glazing, the inside window pane shouldn’t be too cold to touch. The extra insulation also means that unwanted sound is reduced. This makes double glazing ideal if you live near a main road or busy area.

A brief history of double glazing

Traditionally, when homes first started to have windows, one glass pane was used. Although a fabulous solution at first, heat can easily escape through one pane and sound insulation isn’t great with single glazing. You’ll know how cold and draughty a room with single glazed windows can be. Sound insulation is next to none, especially if you’re near a busy road. Modern double glazing was created in the US in the 1930s, but it wasn’t until the 1970s and 80s that it took off in the UK. With minimum standards set out now for UK homes, all new windows must have an energy rating of at least a C.

What benefits can double glazing bring to my home?

The money you can save on your energy bills with double glazing is reason enough to upgrade. Figures from the Energy Saving Trust states that a detached home can save up to £110 a year with A rated windows. With draughts becoming a problem of the past, you won’t need to rely on your heating as much with a more comfortable and warm home. As well as reducing your bills, using your heating less will make your home more environmentally friendly reducing your carbon footprint. Your home’s security is also improved as two panes of glass are harder to break through than one. The amount of condensation on the inside of your windows will be greatly reduced compared with single glazing.
