Hi, We have a 1930's house with semi-circular bay windows. The outside being tiled. We're having the Windows & window sills replaced, so it would be an ideal time to add insulation into the cavity if it were a sensible thing to do. There is quite a gap and we could easily put the rolled insulation down it. I know that houses are supposed to breathe and am bit worried by insulating the gap we could end up creating damp /condensation where currently, none exists.
Any advice?
