Absolute thermal resistance (across the length of the material)

Description

Thermal resistance is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow. Absolute thermal resistance is a specific property of a component.Absolute thermal resistance is the temperature difference across a structure when a unit of heat energy flows through it in unit time
