Vapour barrier


New Member
Hi, I'm creating a utility room. On one of the walls im fastening some plasterboard on to wood battens to hide some pipe work(and insulating in between the battens ) , The battens are in turn fastened to an external brick wall. Should i still put up a vapour barrier on the back side of the inner plasterboard.? I'm guessing i still do this as there will be a difference in temperatures between utility room (could get warm) and the outside?.

Any thoughts greatly appreciated .

Yes but I wouldn’t of fixed the battens to the brickwork (would have at least a 50mm cavity between studwork and external brickwork)
