U-factor ratings: A measure of thermal performance
By Heather Bender
Builders in Canada face challenging climate conditions, which makes accurate thermal performance data key in choosing products for their designs. For manufacturers of commercial roll-up and sectional doors, these ratings have traditionally been presented in RSI-value, which is a measure of a component’s thermal resistance. This single measure, however, is proving inadequate for assessing the complex nature of these dynamic, multi-component assemblies.
