I am looking for some (retrospective) advice on insulating a sloping roof. We have a 1 and a half story stone built house with bedrooms in the roof space with dormer windows. In my wisdom when stripping out the room I insulated in between the roof joists (on the sloping sections) with space blanket style insulation. I am wondering if this was a mistake as it is likely to be reducing air flow which I think is equally if not more important. Could anyone advise if I would be petter to pull this out from the small loft space at the very top of the roof pitch? If so is there anything I can do now to insulate better?
Thanks for your help
