Another thing I may do is install Tyvek across the bottom of the joists as an additional measure. I contacted a DOW engineer and she said that would be an excellent application for Tyvek. She explained that basically a floor is just a horizontal wall. IMO the floor cavity should be protected like a wall cavity. I wouldn't want wind and moisture flowing across the back of the sheetrock in my walls, why would I want it on my floor?
