How long do double glazed windows last?

Double glazing usually lasts for around 20 years, although this can vary from 10-35 years depending on the quality of the materials used, installation quality and weather exposure. Once your glazing has failed, it might still be able to perform the basic functions expected of windows but its thermal performance is likely to be significantly reduced. This is because, over time, the inert gas that is fitted between the sealed unit will begin to seep out, resulting in less heat being trapped between the panes of glass. Once this happens, you should consider replacing your double glazing.

Window replacement

If your windows have failed, they’ll be unable to retain lots of heat, meaning you’ll have to pay more to warm your home. Therefore, it’s important to think about window replacement. If opting for replacements from Associated, you can benefit from a Window Energy Rating (WER) of A as standard. This means the previously lost heat will be kept inside your home and you can save on your energy costs.

Adding house value

Improving your home’s thermal performance is not the only benefit of replacing your windows; new double glazing will almost certainly add value to your home, however, this is provided the replacements are suitable. Suitable replacement windows will enhance or maintain the character of your existing home, therefore it’s important to think carefully about which style and material are best suited to your property. As window experts, Associated Windows can help.

Upgrade to triple glazing?

Triple glazing offers the homeowner an extra boost to thermal efficiency, security and soundproofing. So if you require any, or all, of these benefits, triple glazing is the way to go.
