Fair enough - What about the ventilaition issue though? My loft curently is fairly sealed so I'm intending to fit ventilated soffits (in the future) and not insulate to the very edge etc. Is boarding laid directly over insulation with very little air gap likely to lead to problems (condensation etc) later? If I lay less insulation to give an air gap then I will lose any insulation properties that the boards give as the air will no longer be trapped?
I don't really want to go the whole hog of laying plastic sheet (as a vapour barrier) if I can avoid it hence my thought that the greatest amount of 'damp' air is in the bathroom so I won't boasrd over that...
Thanks for the advice so far...
