    Hi This has probably been asked before but cannot find a thread. I am constructing a warm deck flat roof with joists at 600mm ctrs. I am putting 120mm celotex on with 18mm OSB3 on the top for a GRP system. Can anybody tell me the thickness of board I need to use for the lower deck that sits on the joists please. Is 9mm OSB3 too thin for the base deck? Cheers in advance. Sean
