R-value â Thermal Resistance. Thermal resistance is the temperature difference, at steady state, between two defined surfaces of a material or construction that induces a unit heat flow rate through a unit area, Kâm2/W. According to this definition and Equation 1, Equation 2, therefore, can be obtained.
