My daughter has recently moved to an in excess of 100 year old cottage.
There is very little roof space and part of the bedroom ceilings slope in line with the roof. With the recent heavy frost she noticed that condensation formed on the sloping part of the ceiling. This occured after leaving the window on security opening all night and when heating came on the condensation appeared. Bearing in minde that the space between ceiling and roof tiles is only the depth of the timbers used in the roof construction and that the window and radiator are situated immediately below this section. My proposed solution is to remove the sloping secttion of ceiling and insert insulating material as far as possible, fix a vapour barrier to beams and plasterboard. Is this OK if so what type of insulation and vapour barrier would you use and what type of plasterboard. Also all fireplaces have been blocked off and chimney capped but no ventilation has ben fixed.
