Concrete and heat transfer| Concrete Construction Magazine

Oct 01, 2004· The resistance of a material to conduct heat energy from one surface to another is its thermal resistivity, which for a given area is expressed on a per-unit-thickness basis. For what you describe, a workable resistivity would be 0.09 hr ft2 deg. F/Btu in. Multiplying thatper-inch value times the thickness of the concrete would give you an R-value for the concrete.
