Tapered ENRGY 3®
Tapered ENRGY 3® and Tapered ISO 3™ are rigid roof insulation boards composed of a closed cell polyisocyanurate foam core bonded in the foaming process to universal fiber glass-reinforced facers. Tapered ENRGY 3 and Tapered ISO 3 are designed for direct application to steel and other roof decks to promote positive drainage. Tapered ENRGY 3 and Tapered ISO 3 meet the material requirements of ASTM C 1289, Type II, Class 1, Grade 2 and Federal Specification HH-I-1972/Gen and HH-I-1972/2. Conforms to CAN/ULC S704, Type 2, Class 2 (See CCMC Evaluation Report 13058-L). Tapered ENRGY 3 and Tapered ISO 3 are also available as precut miters and precut crickets.
Tapered ENRGY 3 and Tapered ISO 3 provide high thermal insulation value over metal, nailable and non-nailable roof decks in built-up, modified bitumen and singleply membrane roofing systems. It may be applied using hot bitumen, cold adhesives or mechanical fasteners. The universal facer on the top and bottom side provides a suitable surface for mechanical attachment to a structural deck as well as a suitable surface to apply hot asphalt or cold adhesive. Tapered ENRGY 3 and Tapered ISO 3 are the ideal insulations for both new construction and re-roofing where ponding water or positive slope is a concern.
