The U-factor for Concrete Slabs| Concrete Construction ...

Generally speaking, lower density concrete provides better insulation than higher density concrete. A reasonable R-value for a normal concrete slab can be estimated using an R-value, the thermal resistance per inch of thickness, between 0.1 and 0.2 and multiplying it times the slab thickness. For a inch slab, R-value would be between 0.6 and 1.2.
