The insulating capability of a material is measured as the inverse of thermal conductivity (k). Low thermal conductivity is equivalent to high insulating capability ( resistance value ). [2] In thermal engineering , other important properties of insulating materials are product density (ρ) and specific heat capacity (c) .
