Hi. I am hoping someone can give me some advice on ceiling insulation. We recently moved into a house that has two outhouses below the third bedroom. We plan to convert these into internal rooms when finances permit! However in the mean time the upstairs bedroom becomes very cold as these rooms are not heated so i am looking at trying to insulate the ceiling within these outhouses in the mean time. I was hoping someone might know a fairly quick and cost effective way of doing this as the bedroom is currently too cold for our baby to move into! i was thinking perhaps i could stick some fibreglass insulation panels to the ceiling but not sure if these even exist?? Any ideas most welcome as i need to get this job done before the colder weather gets going.
