Windows with double glazing have two panes of glass. Windows are made up of double glazed sealed units, also known as insulated glass units (IGUs), which are mounted in a frame. Two sheets of glass are connected by a spacer bar filled with insulating gas to form an air gap. As if you were assembling a sandwich from glass bread with air in the middle.
In terms of benefits, double glazing has the most thermal insulation – to keep heat in a room and stop cold air from getting in from outside. The improvement in energy efficiency that double glazing makes was so noticeable in 2002 that all new windows had to be double glazed C rated – except for properties in listed buildings or protected areas.
How does double glazing work?
Your home will be more energy-efficient and soundproof with double glazing. Argon gas isn’t a good heat conductor, so it keeps warm air in and keeps noise out. We tell you how double and triple glazing works, how they’re rated in energy efficiency, and how they make your home more energy-efficient and quieter.

What are the benefits of double-glazed windows?
Here’s why you should have a local window fitter install double glazed windows for you now that you know what they are.
Warmer in the winter – Double glazing doesn’t just help with insulation, but it can also store heat. It is an effective way of maintaining your home’s insulation in the winter.
Energy cost savings – Double glazing makes it easier to heat and cool a room, so you’ll save money on your energy bills. The insulation level will go up if there are more layers of glazing.
Cooler in the summer – Double glazed windows can reduce the heat in your room on a hot summer’s day by trapping some of the external light. It means you don’t have to turn the air conditioner on as much.
Safety – Double glazed windows mean more protection for your home. The seals are tighter, and they’re harder to break.
Less condensation – Double glazed windows help reduce condensation because the airtight seal keeps it away. Condensation builds up in other windows, which leads to mould in the windows.
Less noise – A quieter house coming from more units. It’s imperative to have double-glazed windows if you live near a busy road or in a noisy area.
