DuPont™ Thermax™ XARMOR™ (ci) Exterior Insulation
Toughest, Most Durable Polyiso Insulation for the Thermax™ Wall System
DuPont™ Thermax™ XARMOR™ (ci) Exterior Insulation
Toughest, Most Durable Polyiso Insulation for the Thermax™ Wall System
<br><b>DuPont™ Thermax™ XARMOR™ (ci) Exterior Polyisocyanurate Insulation</b> is the toughest insulation for the patented Thermax™ Wall System. Designed for continuous insulation, <b>Thermax™ XARMOR™ (ci)’s</b> 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.
<br><br>
<b>Thermax™ XARMOR™ (ci) Insulation</b> 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, <b>Thermax™ XARMOR™ (ci) Insulation</b> provides builders with more durability for long-term performance.
<br><br>
With its low perm rating and high insulating value, <b>Thermax™ XARMOR™ (ci) Insulation</b> 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.
