With Ofgem confirming a further rise to the energy price cap from October, many homeowners across Essex and Suffolk are thinking about ways to keep more heat in and costs down this winter. Double glazing is one of the most effective ways to reduce the amount of warmth that escapes through your windows, helping your home stay warmer for longer without leaning more heavily on the heating. Want the practical steps? Read how energy-efficient windows can help you beat the price hikes this winter.
How double glazing reduces heat loss
Double glazing is made up of two panes of glass set close together within the window frame. The real heat-saving work is done by a low-emissivity coating on one of the panes, which reflects heat back into the room, an argon gas fill between the panes instead of ordinary air, which insulates far better, and a warm edge spacer bar around the unit, which cuts down on cold bridging at the frame.
Triple glazing takes this further with a third pane and low-emissivity coating on two panes instead of one, trapping even more heat. It’s highly effective, but the extra panes add weight, so it’s worth talking through the right glazing style for the size and position of each window or door.
Double glazing also adds strength, since two or three layers of glass are far harder to break than one. All of our patio, bifold and French doors are built with toughened double glazing as standard, for extra peace of mind.
A quieter home too
The same trapped air that holds heat in also muffles sound, so double glazing cuts down on outside noise as a welcome side effect, keeping your own household sounds more private and making for a quieter night’s sleep. If privacy is also on your mind, our windows range includes a variety of obscured glass options, ideal for bathrooms, conservatories or bedrooms.

Where it makes the biggest difference
Most uPVC and aluminium single glazed windows, doors and conservatories can have their glass upgraded to double glazing. Timber-framed windows and doors are usually the exception, since the frame itself isn’t built to hold a double-glazed unit, so these typically need full replacement rather than a glass swap. Either way, moving to A-rated glazing can help the investment pay for itself over time through lower energy bills, while using less central heating also means a smaller carbon footprint, for a more sustainable home as well as a more comfortable one.
