Dow THERMAX Sheathing is a rigid foam insulation that effectively reduces condensation for exceptional moisture protection. Dow THERMAX Sheathing is specially designed to have a Class A fire rating and can be used in a range of concealed and exposed applications, above and below grade. Because of the improved fire performance it is best suited for hourly rated assemblies. Thermax Sheathing is a non-structural, rigid board insulation consisting of a glass-fiber-infused polyisocyanurate foam core laminated between 1.0 mil smooth, reflective aluminum facers on both sides. The glass-fiber reinforcement contributes to improved fire performance and dimensional stability. In the USA THERMAX Sheathing can be installed exposed to the interior without a thermal barrier. In Canadian construction Thermax exposed to the interior must be covered with a thermal barrier. Uses: Insulate residential and commercial walls Residential closed (non-vented) crawl spaces Interior basement walls Interior walls of metal buildings Applicable Standards: ASTM C1289, ASTM D2842, ASTM E2178, ASTM E283, ASTM E2357, ASTM E331, UL Classified, 2009 International Residential Code Section 316, 2009 International Building Code Section 2603, NBCC 9.25.2.2, ICC-ES ESR-1659, CAN/ULC S704-03/11, CCMC Listing 08433-L, FM Approved, Florida Building Code
