ValuTherm™ 25 PSI Roof Insulation
ValuTherm™ 25 PSI is a rigid roof insulation board composed of a closed cell polyisocyanurate foam core bonded in the foaming process to universal fiber glass reinforced facers.
ValuTherm 25 PSI 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.
ValuTherm 25 PSI meets the physical property requirements of ASTM C 1289, Type II, Class 1, Grade 3 and CAN/ULC S704. ValuTherm specialty products are also available as tapered panels.
ValuTherm 25 PSI 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 the top and bottom side provide a suitable surface for mechanical attachment to a structural deck as well as a suitable surface to apply hot asphalt or cold adhesives. ValuTherm 25 PSI has been rated in FM Global® 1A-60 and 1A-90 fire and wind-resistant systems for BUR, modified bitumen and single ply systems in specific constructions. It has been classified by Underwriters Laboratories Inc. as an approved roof insulation in numerous Class A roof constructions and Roof/Ceiling hourly fire-rated assemblies, and is classified by Underwriters' Laboratories of Canada.
ValuTherm is not covered under the JM Peak Advantage Guarantee. Refer to the JM roofing membrane systems to identify compatible insulations.
