<br />ENRGY3 is a rigid roof insulation board composed of a closed cell
<br />polyisocyanurate foam core bonded in the manufacturing process to
<br />universal fiber glass reinforced facers.
<br />ENRGY 3 utilizes an environmentally compliant blowing agent con-
<br />taining pentane hydrocarbon to enhance the thermal performance
<br />of the foam insulation. This hydrocarbon has zero ozone depfetion
<br />potential and conforms to the Montreal Protocol established in 1987.
<br />ENRGY 3 meets the physical property requirements of ASTM C 1289,
<br />Type II, Class 1, Grade 2 and CAN/ULC S704, Type 2, Class 3.
<br />ENRGY 3 specialty products are also available as tapered panels,
<br />precut miters and precut crickets.

<br />ENRGY 3 provides high thermal insulation value over metal, nailable
<br />and non-nailahle roof decks in built-up, modified bitumen and single
<br />ply membrane roofing systems. It may be applied using hot bitumen,
<br />cold adhesives or mechanical fasteners. The universal facer on
<br />both the top and bottom provides a suitable surface for mechanical
<br />attachment to a structural deck as well as a suitable surface to apply
<br />hot asphalt or coid adhesives. ENRGY 3 is rated in FM Global� fire-
<br />and wind-resistant systems for BUR, modified 6itumen and single
<br />ply systems in specific constructions. It has been classifietl by UL°
<br />as an approved roof insulation in many Class A roof constructions
<br />and Roof/Ceiling hourly fire-rated assem6lies, and is classified 6y
<br />Underwriters' Laboratories of Canada.
<br />JM supports NRCA Bulletin #9 in recommending that a cover board of
<br />Fesco� Board or %z" (1.27 cm) Retro-Fit'" Board be installed over foam
<br />insulations in hot bituminous membrane systems.
