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.

With the construction industry focused on energy efficiency, …
