WebOct 1, 2016 · The reciprocal of thermal conductivity. R-value aka Thermal Insulance ([R]=m 2 K/W or ft 2 F hr/Btu) It is the thermal resistance of a unit area of a material. This is the most common way for the insulation properties of building materials to be specified. Thermal Resistance (R θ =K/W) Thermal resistance relates the change in temperature ... Webthe effective thermal conductivity. The parallel, series, and a combination of parallel and series heat flow are usually utilized to develop models that predict the effective thermal conductivity of porous media. All these models end up with equations where porosity is used as an average weighting factor. In some cases, additional weighting is the effective thermal resistance between the conductor and the ambient conditions, which can require significant empirical or theoretical effort to estimate.
