Ideally a vapor barrier would be behind your ceilings. Do you have any roof decking beneath the metal? Is there opportunity to vent the attic?
I have a metal roof on a cabin and I noticed condensation forming inside. I want to insulate, do I need a vapor barrier between the roof & the insulation? if so, what can I use?
Thanks - Pete
Metal roof (no ridge vent) over 2x6 studs. It is an open area I want to insulate but I don't want the insulation to get wet from condensation.
