Replace Frames or Just Glass?

[Stuart Frost]

Hi.

We had double glazing fitted with new upcv frames around 20 years ago and some of the glass units have failed. We are going to get some quotes to have them replaced but just wanted to ask whether the frames would also need replacing given their age ? They are generally in good condition but have things changed with regards to how they’re made or what they’re made of etc?

Thanks

Stu

It's possible, maybe even probable, that the upvc profiles used in modern installs are more thermally efficient than those of 20 years ago. And, depending on the overall quality of components used, things like locking mechanisms are likely to offer enhanced security. I'm basing my response on the assumption you'd opt for a half decent product. If you go cheap as chips my assertions might not hold true, especially the second one.

Hope this helps.

Modern one's are made of PVCu

Depends how much money you want to spend...

if you are looking at spending a bit that upgrade the frames . You could just upgrade the glass to more modern thermally efficient glass ( Diamnt Glass , Warm edge spacer , argon gas and planitherm ) and you will get some heat retention. honestly if the frames and locks/hinges are good and they still look good ..and you've never had any issues with the quality of the window fitting from 20 yrs ago , i'd just change the glass to the modern version. potentially save thousands of pounds and loads of mess. It is unlikely you will ever see back the extra cost of new windows in energy savings over say , 20 years..possibly longer
