Personally,not much. Unless you use a very dense styrofoam, which by definition would have a lower insulating value, it will compress over time and then the screws would have to pop out, or the playwood would flex. Use the sleepers, but put the foam between them.

: It has been suggested that a good method of creating an insulated floor in a basement (on concrete) is to simply glue rigid insulation (the blue stuff) to the concrete and then 5/8" plywood on top, screwed through the insulation into the concrete. No sleepers under the plywood.

: Sounds reasonable to me, what does anyone else think?
