Lightweight, thin, and low-profile fire-rated duct wrap for industrial applications.

Its high flexibility and thin profile make it ideal for duct enclosure systems, serving as a proven alternative to 1- and 2-hour fire-resistant shaft enclosures for grease ducts. Performs in temperatures up to 2192°F/1200°C. Certified to ASTM E2336 (grease duct) and ISO 6944 (air duct) standards, and tested/listed with UL and Intertek. Meets key life safety codes including IBC, IMC, UMN, and NFPA.
