We are buying a Victorian house with a lot of UPVC and some wooden windows. Some of the UPVC are getting quite old and a couple have cloudy glass. I know that many people love them, but I really struggle with them on older houses. Would I be totally insane to replace with wood? As well as aesthetics, I don't like how the UPVC ones, only open at the top - not great for ventilation or as an escape. Has anyone else done this? How do you feel about it now?
