Question Finishing Basement Floor

I am going to finish the poured concrete floor in my basement. I planned on putting down 6mil vapor barrier on the floor first, then secure treated 2x4 sleepers (with 3 1/2" side down) at 16" O.C. with concrete screws at 24" O.C. Then use 1 1/2" thk. rigid insulation between sleepers. And top that off with 3/4" thk. tongue & groove OSB secured to sleepers.

Does this sound like I'm on the right path? Or should I put the vapor barrier on after adding rigid insulation, but before the 3/4" OSB?

Should the rigid insulation be foil faced? If so, the foil to be up or down?

Should the sleepers be at 16" or 12" O.C.

Thanks in advance for your help

Your plan is just fine. I would add construction glue between the sleepers and sub flooring. This will cut down on possible squeaks. Also don't forget to shim the sleepers for level.

Hope this helps.
