Product Description

Designed for continuous insulation, Thermax (ci)’s 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(2) available for immediate insulation and weather protection on the job site, as well as long-term thermal performance.

Thermax (ci)’s integral durable thermoset coated aluminum facer provides a drainage plane and water resistive barrier, eliminating the need for a membrane or building wrap when used in conjunction with DuPont Flashing Products. With its low perm rating and high insulating value, Thermax (ci) helps reduce the potential for condensation within the wall assembly. Thermax (ci) is also manufactured using a distinct free-rise technology using a unique fiberglass core for better product consistency, durability than generic polyisocyanurate insulations.

Ease of Installation
Thermax XARMOR (Ci):

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

Available Sizes
Sizes, R-values and edge treatment options for Thermax (ci) can be found in Table 1 of the TDS located in the tab below. Contact your local sales representative for additional sizes.

Sustainable Solutions
Thermax (ci) Exterior Insulation is manufactured with a zero ozone depleting potential blowing agent. The use of Thermax brand insulation helps reduce the carbon footprint of commercial buildings. Thermax is compliant with California Department of Public Health (CDPH) VOC emissions requirements.
