What is Thermal resistance?

Thermal resistance is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow. Thermal resistance is the reciprocal of thermal conductance. For a wall, it is obtained by dividing the length of the wall along the heat flow by the product of its thermal conductivity and the area perpendicular to the heat flow.
