Vapor Barrier on Deck Floor?

I live in New Hampshire, I have a deck built out of pressure treated
wood 8-10 inches of the ground. A 12x12 screen room was built on top
of it. I am now making it a 3 season room with the addition of new
windows droping a ceiling and plan on insulating all the way around.

I want to insulate the floor but am not sure on where to place the
vapor barrier. What I thought of doing was adding another layer of
2x6's on top of the pressure treated decking and adding insulation
between the new floor joiist. The ground below the original deck does
not have any plastic covering it and it would be hard to instll it at
this point because of the low clearance. The deck is open all around
for good air circulation.

Should I use insulation with paper and should the paper be just below
the new floor or just batting and no paper?

Any ideas?
