615+ 24" x 25 ft. Fire Barrier Duct Wrap

The 3M Fire Barrier Duct Wrap 615+ is a flexible fire-resistant wrap consisting of an inorganic fiber blanket encapsulated with a scrim-reinforced foil. It is used to fire rate commercial kitchen grease ducts as well as ventilation ducts. The 615+ duct wrap is a proven alternative to 1- or 2-hour fire-resistant rated shaft enclosures for grease ducts (ICC-ES ESR-1255). With its excellent insulating capabilities, low weight and thin profile, it is an ideal choice for a duct enclosure system. This non-asbestos wrap installs easily due to its high flexibility and strength. Features: Two-layer wrap for grease ducts rated as a shaft alternative per ASTM E2336 Zero clearance to combustibles throughout the entire enclosure system for congested spaces Butted inner layer in 2-layer grease duct applications One-layer wrap for fire-resistive ventilation ducts per ISO 6944 Type A High flexibility for installation ease Foil encapsulated for blanket protection, less dust, and high wrap strength Widest range of penetration seal systems Blanket adhered to foil scrim
