About this product
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
