Source sentences:
text: In order to calculate heat flow, it is first necessary to calculate the thermal resistance ("R-value") for each layer of insulation.
text: The higher the thermal resistance (R-value), the greater the insulating effect.
text: This means that VIPs have about one-fifth the thermal conductivity of conventional insulation, and therefore about five times the thermal resistance (R-value) per unit thickness.
