← All Topics

Double glazed windows last, on average, for around 20 years, but this lifespan can vary from 10 to 35 years depending on the quality of materials, installation and where your windows are fitted.

Having double glazed windows installed is an investment that pays off over time, reducing your energy bills, increasing the value of your property and ensuring that you can enjoy a condensation-free, comfortable home environment. 

But just how long can you expect your double glazed windows to perform their best? According to the Centre for Sustainable Energy, double glazed windows last an average of twenty years before they require replacing. The exact lifespan of your double glazing will depend on a range of factors, such as the quality of materials used, the quality of the installation carried out and the stresses and strains put on your windows by weather, usage over time and external factors. 

Brackenwood uses only the highest quality materials in our double glazing installations. Our uPVC windows and aluminium windows come with A-rated double glazing and are thermally efficient, helping to reduce your energy bills by up to £30 a month. All of our windows benefit from increased security provided by the SAC Shootbolt locking system, which also takes pressure away from the hinges and ensures a longer life for your windows. 

To ensure your double glazed windows last as long as possible, select an installer with the BSI Kite Mark — a sure sign of quality and reliability. Brackenwood is proud to be a member of the CPA, Approved Craftsman and holder of the BSI Kitemark for installations. Our customers are delighted with our quality of service — that’s why we’re rated 4.7/5 on independent rating platform Feefo. You can rest assured that your windows will last as long as possible when you choose to have them fitted with us.
