THERMAX™ Sheathing is a non-structural, rigid board insulation consisting of a glassfiber-reinforced polyisocyanurate foam core laminated between 1.0 mil smooth, reflective aluminum foil facers on both sides. The glass-fiber reinforcement, along with chemical modifications, contributes to improved fire performance and dimensional stability. THERMAX Sheathing has a Class A fire rating and can be installed exposed to the interior without a thermal barrier. #06_16_13 #06160 #cavity_wall #DBS #DOW #Dow_Building_Solutions #DOW_Chemical #insulating_sheathing #rigid_insulation #THERMAX #wall_insulation
