Definitions for "Thermal resistance"
the ability of a given thickness of a substance to prevent heat transfer.
The measure of a material’s ability to resist heat flow. The formula for Thermal Resistance is R = L / k where (L) is the material’s thickness and (k) is the material’s Thermal Conductivity constant. The higher a material’s R-value, the better it insulates, and conversely. For more information, click here.
(R-value) - A property of a substance or construction which retards the flow of heat; one measure of this property is R-value.
