ENRGY 3®
ENRGY 3® is a rigid roof insulation board composed of a closed cell polyisocyanurate foam core bonded in the manufacturing process to universal fiber glass reinforced facers. ENRGY 3 utilizes an environmentally compliant blowing agent containing pentane hydrocarbon to enhance the thermal performance of the foam insulation. This hydrocarbon has zero ozone depletion potential and conforms to the Montreal Protocol established in 1987. ENRGY 3 meets the physical property requirements of ASTM C 1289, Type II, Class I, Grade 2 and CAN/ULC S704, Type 2, Class 2. ENRGY 3 specialty products are also available as tapered panels, precut miters and precut crickets.
ENRGY 3 provides high thermal insulation value over metal, nailable and non-nailable roof decks in built-up, modified bitumen and single ply membrane roofing systems. It may be applied using hot bitumen, cold adhesives or mechanical fasteners. The universal facer on both the top and bottom provides a suitable surface for mechanical attachment to a structural deck as well as a suitable surface to apply hot asphalt or cold adhesives. ENRGY 3 is rated in FM Global® fire- and wind-resistant systems for BUR, modified bitumen and single ply systems in specific constructions. It has been classified by UL® as an approved roof insulation in many Class A roof constructions and Roof/Ceiling hourly fire-rated assemblies, and is classified by Underwriters’ Laboratories of Canada.
JM supports NRCA Bulletin #9 in recommending that a cover board of Fesco® Board or 1/2" (1.27 cm) Retro-Fit™ Board be installed over foam insulations in hot bituminous membrane systems.
