Whats the situation with the vapour barrier ? My roof is sterling board which was supposed to be temporary, but wound up permanent, on top of the board, i bolted corrugated iron sheets, its ok, does not leak, but needs insulating. Do i need a vapour barrier ?
I placed a vapour barrier between the exterior cladding and the stud walls. I'm told it's good practice to do so as moisture will exit from the building via the vapour barrier but won't be able to re enter.
I've also placed 12 mm plywood over the rafters and a vapour barrier over that. Like you a metal roof is planned. However I'm thinking I might insulate with Celotex between the rafters then cover that with plywood.
