(That's Contr-o-versy ...)

I should add that it's not uncommon to have 6 mil polyproplyene installed on the HEATED side of the rooms that face the outside or an unheated attic. But what you're talking about sounds like the inspector wants you to put the plastic on TOP of whatever insulation it is you use. Personally, I don't recommend it, but others will disagree ...

When the plastic is on the HEATED side of the home, even with leakage through the walls/ceiling, the warm air moves very slowly THROUGH the insulation, thus, keeping the 'space' just above the plastic dry. FWIW, the way insulation works is it 'traps' air, slows its movement, thus creating an insulating effect. And if the air being trapped is 'warm', all the better! All in all, the insulating effect helps to keep air from exiting the house at a rapid rate compared to NOT having insulation.

My best to ya and hope this helps. Others???
