THERMAL PROPERTIES CHART:

• U Value - The Lower the Number the Better the Insulator
• R Value - The Higher the Number the Better the Insulator

To follow is a comparison of thermal properties of some of the more common materials used in building windows. This information was retrieved from several different sources; therefore the accuracy may vary somewhat.

The two most common units used to evaluate thermal properties are U-value and R-value. The U-value is defined as the amount of conductive heat energy (BTU's) transferred through a one square foot area For each 1° temperature difference between the indoor and outdoor air. Units are BTU/hr/ft²/degreeF. The lower the number the better the insulator.

The R-value is just a different way of looking at the same concept. The R-value is the reciprocal of the U-value. R measures the ability of a given material (barrier) to resist the transfer of heat through a one square foot area for each 1° temperature difference. Units are Hr/ft²/degreeF/BTU. Both units are per inch of thickness. The higher the number the better the insulator.
