Floors: T&G? Pressure treated?

I'm hoping to get floors in this weekend (on an unframed, 1" polyiso foam board base). There's just so many options!

I've narrowed my choices down to regular tongue & groove subfloor or standard pressure-treated (not T&G). Both have advantages.. The PT might hold up to damp climes and water leaks a little better. The T&G will ensure my boar seems don't misalign causing odd bumps in the living area. Which would you go with?

Most won't put pressure treated wood in their living space. I used standard 3/4 inch tongue-in-groove over 1 inch of 15 psi polystyrene insulation. The polyiso foam boards I've dealt with don't have much of a compressive load rating, so an installation without sleepers I would worry about it being squished.

Thanks. Looks like it's another trip back to Menards... I'll go with the "outdoor rated" non-treated 3/4" T&G.

The polyiso stuff is rated at 16PSI. If the 15PSI polystyrene is holding up, this should, too. I won't have any point loads (beyond my own footsteps). I'm trying to minimize framing, but I suppose I could put a sleeper down the middle of the heavy traffic area. All furniture (dinette, cabinetry, bed, etc.) will be framed so no point loads to worry about there.

Thanks again, y'all! I love this website!
