Updated: Jan 12, 2023

Double glazed UPVC windows are a great way to improve the energy efficiency of your home. Not only will they keep your house heated during winter, but they will also save you money on your energy bills. Installing double glazing will also significantly increase the value of your home. They can be quite the investment, however, so you might be wondering how long they will last before you have to pay again to replace them. This blog will cover just that, along with some tips on how you can prolong the lifespan of your double glazed windows.

What is the Lifespan of Double Glazing?

On average, double glazed windows will last between 10 and 20 years before they will need to be replaced. However, this is only a rough guideline - some UPVC windows could last longer, whilst others might need to be replaced much sooner.


As a general rule of thumb, if you start to notice any condensation on the inside of your windows, or draughts around the window frame, it’s a good idea to get them inspected. In most cases, minor repairs can help to extend the life of your windows, but of course you will still need to replace them eventually.


When it comes to maintenance, UPVC double glazing doesn't require anything more than routine cleaning. However, it’s always important to check the seals around your windows periodically, as they can become damaged over time or suffer from high humidity, which in turn can lead to a build-up of mould around the sills and sealant.


Additionally, if you notice any cracks or gaps in the sealant, new sealant can simply be applied over it. By caring for your UPVC windows properly, you can enjoy their many benefits for years to come without requiring a replacement.


What Factors Can Impact How Long Double Glazing Lasts?

There are a number of factors that affect how long your double glazed windows last, including the quality of the windows and the location of your property. For instance, windows installed in a sunny spot will be subjected to more thermal strain than those in a shadier one. As a result, they might not last as long as windows in a more sheltered location.


Air conditioning and draughty windows also play a role. This is because air conditioning can cause the seals around windows to become worn, and draughty windows can lead to more heat to transfer between the inside and outside of your building.


Lastly, poor workmanship during the installation process can impact the amount of time before replacement windows are required. Ill-fitting window frames can let in draughts and air leakage, which can decrease the window’s energy efficiency.
