Product Description

Thermax XARMOR (ci) 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) provides builders with more durability for long-term performance.

With its low perm rating and high insulating value, Thermax XARMOR (ci) 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.

Ease of Installation
Thermax XARMOR (ci):

• Eliminates the extra step of installing a membrane or building wrap when used with LiquidArmor and DuraGard CM.
• Is optimized to go behind rain screen exteriors
• Contains UV-stable technology – can remain uncovered up to six months
• Reduces the potential for condensation within the wall assembly
• Is lightweight – easy to cut, handle and install

High Performance Durability
With more than 30 years of exceptional performance, Thermax™ Brand products feature a distinct free-rise technology for better product consistency, durability and fire performance than generic polyisocyanurate insulations.
