We have two back doors, both in different rooms, both with about 12 panes of
6x9 glass (or so) in them.There is nothing wrong with the doors apart from they need a paint and some of the glass is mismatched. I thought I'd strip them both down, and replace the glass with new clear and wondered if I should 'upgrade' the glass in an effort to make our house ever so slightly warmer (I have an ongoing project to remove draughts etc).
Is it worthwhile? If so what sort of spec glass should I go for?
TIA
