THERMAX Sheathing rigid insulation from Dow joins a core of glass-fiber-reinforced polyisocyanurate foam with aluminum foil facers. The insulation delivers outstanding thermal performance (R-6.5** at one inch) with high moisture resistance, reliable dimensional stability and exceptional fire performance. THERMAX Sheathing meets or exceeds building code fire performance requirements for foamed plastic insulations and can be used in a variety of hourly rated wall assemblies. The insulation is easy to handle and install, and it can be left exposed to the interior without a thermal barrier, making THERMAX Sheathing an ideal choice for many facilities.
