I'm building the floor system for a screened in porch. Rectangular in shape. CMU support walls all around. I'd like to use a wood floor system with treated 3/4" plywood, then Durock, and finish it with a tile of some type.. The ledger boards are treated, of course, but I'm wondering if the 2x joists need to be as well. I mean, this is really no different than any other room. or is it? The joists here shouldn't be any more susceptible to attack than the rest of the house.
