Leland:
I'd be concerned of cases where foam insulation installed in stud walls
forces all the vapor migration through the wall, to pass through the
studs, overloading the studs with moisture causing decay in the studs.
I've seen two case where it looks like that was happening, though we did
not have the budget to investigate and prove it.
