hi folks hoping some can tell what is the minimum air/breather gap you need between the roof tiles/membrane on the inside of the roof and the finished plaster board.
The roof trusses are 4 inch thick could I get away with putting 2 or 3 inches of kingspan and leaving a 1 or 2 inch air gap
hope this is clear
cheers
