We really need to change our double-glazed windows at the front and back of the house. They are currently aluminium frames which have been installed inside the original timber window frames. The gap between the glass panels is smaller than currently recommended, plus the original timber is in a terrible condition and there is a lot of water coming in through the frames.
I'm not entirely convinced myself whether timber clearly wins out over PVC, partly due to reading some FoE reports about the timber trade. But I would rather have timber frames than uPVC - mainly considering the energy that goes into manufacture and the fact that they will not be recycled when they are eventually removed.
I read on a CAT report that double glazing using sustainable timber frames shouldn't cost much more than PVC in any case. But that's not been our experience.
Based on the quotes we've had so far, dp is very persuaded by the cost difference and really doesn't want to shell out loads more money to appear a little bit more eco-friendly.
Oh, and his parents had some PVC double glazing installed ages ago and never had any problems with maintenance. So I know some cheaper ones may not last, but that argument won't wash with him either.
Any comments?
