DuPont™ Thermax™ XARMOR™ (ci) Exterior Polyisocyanurate Insulation is the toughest insulation for the patented Thermax™ Wall System. Designed for continuous insulation, Thermax™ XARMOR™ (ci)’s glass-fiber-reinforced polyisocyanurate foam core is homogenous – featuring finer cell size and better cell orientation, reducing voids and knit lines – resulting in one of the highest R-values available for immediate insulation and weather protection on the job site, as well as long-term thermal performance.

Thermax™ XARMOR™ (ci) Insulation is also the only Thermax™ Insulation with a dark exterior facer optimized to go behind rain screen exteriors. Its integral, durable thermoset-coated aluminum facer provides a drainage plane, water-resistive barrier and exterior sheathing; eliminating the need for a membrane, building wrap or exterior gypsum. Boasting a strong 4.0 mil embossed, acrylic-coated exterior foil facer, Thermax™ XARMOR™ (ci) Insulation provides builders with more durability for long-term performance.

With its low perm rating and high insulating value, Thermax™ XARMOR™ (ci) Insulation can help reduce the potential for condensation within the wall assembly. Thermax™ is also manufactured using a distinct free-rise technology using a unique fiberglass core for better product consistency, durability and fire performance than generic polyisocyanurate insulations.
