Hi everyone! I am installing some rigid insulation in my vaulted ceiling at the weekend and wondered if anyone could give me some pointers..
the rafters are 8 x 2 so I was going to use 150 or 125mm boards and 30mm insulated plaster board.
foil side to the room or the roof?
I know I need to leave a 50mm (500mm might be a bit big) gap between the membrane and the insulation board, but do I need to fill every tiny gap in the rafter with insulation - and seal it nice and tight with foil tape?
any other little tips to save me time?
thanks for nay time you take to reply, these forums have been invaluable to me in the last few weeks and I really do appreciate everybody's help!
