  • Class A fire rating
  • Low perm rating for reduced condensation
  • Variety of thicknesses (1/2" to 2") and R-values (3.3 to 13.0)

One Product, Many Insulation Applications

DuPont THERMAX sheathing can be used in both commercial and residential walls including non-vented crawl spaces, interior walls of metal buildings, and interior basement walls. It can be installed without a thermal barrier and can also be used with hourly rated assemblies. The sheathing’s reinforcing facers contribute to fire resistance and durability, as do its chemical modifiers.

Lightweight and easy to install, DuPont THERMAX can be easily cut using a knife or saw and can be installed on both walls and ceilings including girts, steel studs, block, wood, tilt-up, purlins, trusses, and bar joints.
