Morning all. Ordinarily I’d make a stud wall. Fill with celotex cover with a Vapor barrier and board over. But a local builder suggested just to ‘dot dab’ pre insulated boards to the wall. My first though was that they wouldn’t stick very well. But could be mechanically fixed. That said what about the vapour barrier? I can’t seem to find any boards that categorically say they incorporate this. Is it a bad idea/dodgy builder short cut?
