Thermal Resistance (R-Value) is a heat property measured the temperature difference by which an object or material to heat conduction that is the capacity of a material to resist heat transfer such as a layer of insulation, a window or a complete wall or ceiling, resists conductive flow of heat. The R-Value measures the thermal resistance per unit of a barrier’s exposed area, the greater the R-value the larger the number.
