By replacing the single glazed windows in your home you stand to make savings of around £170 each year. It’s not just the financial gain that makes double glazing attractive though and you can also save up to 680kg of carbon emissions annually. Over 20 years this is a saving of around £3,400 and 13,600kg of CO2.
As well as keeping your home warmer and reducing noise, you’ll notice a saving on your energy bills from installing double glazing. If you install A++ rated windows in your home after having single glazing, you could save up to £120 year on your energy bills. The Energy Saving Trust has more information.
If you’ve got a problem with condensation and don’t have double glazing, you should find that getting new windows will help. Condensation is caused by warm air meeting a cold surface which then turns into water droplets. With two panes of glass, less heat will escape from your home and keep the window warmer, meaning when steam from the bathroom or kitchen touches your windows there should be less condensation.
Double glazing frames don’t just have to come in uPVC and are available in other materials including aluminium and wood too. Wooden or timber windows are more suited to properties with a traditional look and are often the frame of choice for listed buildings and homes in conservation areas. When properly maintained wooden windows can last well for years but can be up to three times more expensive than uPVC.Aluminium is the strongest and most durable option. As a metal it is highly resistant to the UK’s changing weather conditions and won’t rust, warp, crack or peel. Aluminium offers a modern appeal and is available in a range of colours.
