FAQs

What happens if I have problems with my new windows?

Ultimately the double glazing company you use is responsible for the quality of work and to ensure your windows are of an excellent standard. This is why it’s important to get a warranty and use a Fensa registered installer. If problems emerge within a couple of years then it’s likely the installation was of a poor standard.Contact the double glazing company and have the issue repaired or new windows replaced. This doesn’t matter if you received a discount of free windows as part of the deal. As long as you entered into a contract the company is obliged to restore the windows.

What are the other double glazing options?

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.

how long does double glazing last?

Just like every other thing in your house, your double glazed windows have an expected lifespan attached to it as it gradually becomes less functional and less efficient over time. Although there are actually top quality windows which are able to last a very long time, but the fact still remains that nothing can stand the test of time or last forever. Even the best quality double glazed windows will eventually need to be replaced at some point. So exactly how long do double glazing windows last before need a replacement?

To make it brief, most double glazing window units are typically expected to last an average of 20 years. This number of years can, however, vary within the range of 10 to 35 years based on the several factors such as the type, quality of materials as well as installation and where the windows are located.

The reason for the depreciation in double glazing windows is, over time, the windows may be subjected to some wear, tear as well as all kinds of minor damages which includes gas filled insulated glazing unit slowly and gradually leaking. According to the Centre for Sustainable Energy, the evaporation of 25 percent of gas will ultimately minimize the windows’ thermal performance. And when this occurs, fitting a secondary glazing measure or replacing the windows should be put into consideration.

Another factor leading to the gradual depreciation in double glazing windows over time has to do with condensation. When the window collects between the layers of glass due to the failure of the seal of the perimeter and the saturation of the desiccant, can only be solved by IGU replacement.

And finally, the ravages of time also has a way of taking its toll on double glazing windows. This can happen in so many ways such that the window becomes a lot less efficient and later needing to be replaced.

How much money will I save with double glazing?

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.
