I'm installing a new t&g fir floor, the floor is around two and half feet above an open space. There was some old insulation below that I have removed. I plan to install unfaced insulation and a half inch plywood sheathing to the bottom of the joists to keep the critters out. I also plan to install a 6 mil plastic over the existing floor deck (under the the new fir) as a vapor barrier, is this a good plan?
