Hi All,
I was wondering what thickness of insulation would be needed for a warm roof (to go on an extension). Looking about I cannot seem to find the nominal thickness that would be required as I'm trying to draw up some plans. Am I correct in assuming you have ply, vapour barrier, insulation, ply and then felt covering
Cheers
