Thermax™ XARMOR™ (ci)
Designed for immediate insulation and weather protection on the job site, as well as long-term thermal performance, DuPont™ Thermax™ XARMOR™ (ci) Exterior Insulation is a rigid foam board insulation with a glass-fiber-reinforced polyisocyanurate foam core that helps improve fire performance and dimensional stability. The homogenous foam core features finer cell size and better cell orientation, reducing wormholes and knit lines. The result is one of the highest R-values available (R-6.5 at 1”). The core’s tough, 4-mil gray exterior facer provides durability and long-term performance. Used in the DuPont™ Thermax™ Wall System, DuPont™ Thermax™ XARMOR™ (ci) Exterior Insulation can help you design for the future, while its light weight and ease of installation save time and money on the job site. DuPont™ Thermax™ Brand insulation delivers wall performance you can count on. It’s ready to meet your toughest building challenges – both outside and inside the wall – with a robust ISO insulation product line and an R-value that’s proven consistent over time and a range of temperatures.

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.
3Calculated flammability values for this or any other material are not intended to represent hazards that may be present under actual fire conditions.
