Definitions for "Thermal conductance"
A constant, equal to a material’s k-value (Thermal Conductivity) divided by the material’s thickness in inches; used often for materials of composite construction such as insulation. For more information, click here.
time rate of heat transferred through a composite structure separating two temperature zones (for planar components: product of U-value and area) [W/K]  (Wärme-) leitwert
The heat conduction power of a substance; substances with a very low thermal conductance are called insulators.
