Thermal resistance definition
Thermal resistance or “R-value” means a measure of the ability to retard the flow of heat. The R-value is the reciprocal of thermal transmittance or U-factor expressed as R= 1/U.
Thermal resistance. (R-value) means the resistance to the flow of heat of a particular body or assembly. “R-value” is measured in the United States customary units, ft2-hr-degrees F/Btu.
Thermal resistance means a measure of the ability of materials to retard the transfer of heat.
