Here is a drawing of what I am doing.
The corrugated steel guy recommended I use a vapor barrier behind the steel. After reading AC Hacker's input about thermal gradient I think it would be better to put it inside the house between the drywall and the studs. I think I won't put any behind the steel because 2 layers of vapor barrier separated by 15-16" might trap moisture between layers. What do you think?
*** tried to post picture but I don't have enough posts. this should be my fifth post so I'll try again after this
