Optimized to place behind rain screen exteriors, Thermax™ XARMOR™ (ci) Exterior Insulation is the toughest insulation available for the Thermax™ Wall System. A 4.0 mil embossed exterior foil facer provides durability and long-term performance.
Thermax™ XARMOR™ (ci)
Thermax™ XARMOR™ (ci)* 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 wormholes and knit lines – resulting in one of the highest R-values(2) available (R-6.5 at 1”) for immediate insulation and weather protection on the job site, as well as long-term thermal performance.

1Aged R-value at 1” of cured foam @ 75°F mean temperature. R-value expressed in ft2 •h•°F/Btu. R-value determined by ASTM C518 using the aging process in ASTM C1289 (90 days @ 140°F)
2Vertical compressive strength is measured at 10 percent deformation or at yield, whichever occurs first.
