insulate a cement floor - not a basement floor

we have just purchased an old home, the last owners added a new addition but only have a subfloor screwed into the cement base, how can we insulate this floor so it will not be so cold. We were thinking of putting Dri Core on top of the existing subfloor?? what is the best cheapest way of insulating before we put down carpet

Other then treated wood, no form of wood should ever have been installed directly to the slab.

If this floor is dry and above ground what I did was layed blue foam down on the floor (I used 1") and installed 3/4" T X G Advantech subflooring then Tap coned it to the slab.
The floor is now far warmer, it does not move at all and was far cheaper to install then Dri Core.

Depending on your visual preferences and the use of the room, these 2'x2' hard foam pads (sometimes multi-colored) that interlock and are used in kids' play areas, etc, do wonders for improving heat loss through the feet. They are cheap, fast and easy, but if the room is used heavily and constantly, something more skookum may be better.
