Thanks both for those links. Come to think of it, I think I even read the second one, if not the first. I esp like this, from the conclusions: "Instead of a vapour barrier, these results suggest that an air barrier might be all that is required to
control condensation in the below-grade portion of the basement wall." That ought to be enough to convince an inspector that poly is not the best in this situation.
