Vapour Barrier??

[winger1979]

Hi
I am converting a brick built garage into a living space (will have radiator and backs on to a conservatory which attaches to house) . Garage door has been bricked up with window.

Question regarding walls - do i need to install a vapour barrier? I seem to be finding conflicting advice online??

I have single skim brick walls / 50mm insulation slab and then plasterboard with moisture check.

If so install next to plasterboard?

Many thanks in advance

If your p/b already has a moisture check you wont need to install an an additional vapour barrier.
