Raised wood floor

Hi all, first post. Very cool site....
I've got a quick question, I just received about 200 sq ft of used oak flooring and I'm also in the process of completing my oak bar on my unfinished first floor ( not really a basement since the house is on grade). Since this is a temporary thought, till the room is finished, could I staple a moisture barrier and padding plastic foam to the underside of 1/2 in particle board and frame the particle in 1 1/4 in trim and lay the old hardwood in to create a "raised" hardwood platform under the bar area? Does this seem like a plausible idea, there are no concerns of moisture or significant water in the area (aside from the occasional bar spill).

Ok thanks, since this was a temporary use until I can finish the entire room, drywall electric etc, I was hoping to get away with using the foam under the particleboard as both padding and moisture protection (of which there is very little. This a one year old modular house built on grade, with the first floor unfinished.

Thanks, I start looking into the exterior ply pricing...

Yes It is a poured concrete floor in a bi level house, the first floor is really on grade with rest of the neighborhood, there is very little hydrostatic pressure under the floor. I'll use the foam padding as if I was laying pergo and tape all the seams

Unless there is a vapor barrier under the concrete, the slab will allow transfer of moisture from the earth below. i've had to rip up more than one wood application on concrete because it swelled, buckled, expanded, heaved - both ply and hardwood. Installing ext grade ply only means the glue shold not breakdown under moisture. it does not mean the wood will not absorb moisture and expand and swell. research a good quality vapor barrier for your application.
