I will be decorating the living room soon - wallpaper, paint and carpet etc.. but before that we still have this annoyance.
We have 30 year old upvc windows and get a lot of condensation despite being ventilated and having a dehumidifier. We have ruled out any leaks. Its only in cold weather and not after rain. The Pvc is thin stuff and looses a lot of heat. Nothing wrong with the window glass as far as I know.
I'd like to box up the internal area below window and use good insulation. It should reduce heat loss a lot and minimise the cold surface area for condensation to form on.
As I understand it, insulation is bad with porus or cavity walls, as it will get damp, never drying out, but PVC should not be porus.
Keeping warm, moist air away from the cold bits will be a good idea?
Good idea or leave it alone? Suggestions please
