Windows are a substantial investment for any home, with many homeowners spending thousands of pounds to install or replace them. With that in mind, how do the windows themselves measure up against the cost? What sort of lifespan can you expect for double glazing?

We have taken a look at some of our most frequently asked questions when it comes to how long double glazing lasts and how you can tell if your double glazing needs replacing.

What is the lifespan of double glazing?

The lifespan of double glazing ultimately depends on the level of quality in the manufacturing and what materials your windows are made from.

To get a better idea of how long you can expect your double glazing to last for, you should look into the length of the warranty offered by your window manufacturer. Most manufacturers offer a guarantee of around ten years, with others boasting slightly longer. Each manufacturer is different, which is why you should check this with your supplier. That will tell you how long your double glazing should last for at the very minimum.

What causes damage to double glazing?

If you opt for UPVC or aluminium units, there is no risk of rot or damp damaging your double glazing, which means that any risk factors can really only come from external force being applied.

However, in order to avoid ‘blown’ or ‘cloudy’ double glazing, you should ensure that all seals are installed correctly and protected against wear and tear.

When it comes to the glass itself, most windows will feature toughened glass that can only be broken from the corners, a risk which is almost non-existent when the glass is set within a window frame.

Signs that you need to replace your double glazing

Replacing your double glazing might be something you’ve been putting off for some time due to the cost, or it could be something you’re not even aware you need to do.

The signs to look out for when deciding if it’s time to replace your double glazing are:

  • Noticeable draughts that you can feel around the windows
  • Chips or cracks in the windowpane
  • Malfunctioning mechanisms or difficulty using your windows
  • Condensation between the two panes of glass
  • Water leaking in around the windows
  • An increase in your energy bills

If any of the above apply to your current windows, it might be worth getting in touch with your local window expert so they can take a look at the double glazing itself and recommend the best steps for you to take.
