1 in. x 48 in. x 96 in. R-5.7 R-Panel Polyiso Roof Foam Board Insulation, Universal Facer | FMP1.0-RPR-48-JM

Johns Manville R-Panel 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. R-Panel meets the physical property requirements of ASTM C1289-01 Type II, Class I, Grade 2 and CAN/ULC S704, Type II, Class 3.

• R-Panel 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 sides provides a suitable surface for mechanical attachment to a structural deck as well as a suitable surface to apply hot asphalt or cold adhesives
• R-Panel meets the International Building Code requirements for a foamed plastic roof insulation
