Lightweight, Thin and Low-Profile Protection
Our 3M Fire Barrier Duct Wrap 615+ is a fire-rated duct wrap consisting of an inorganic fiber blanket encapsulated with a scrim-reinforced foil. Because the blanket is adhered to the foil scrim it will resist wrapping and slumping. This non-asbestos wrap installs easily due to its high flexibility, low weight and thin profile – making it an ideal choice for duct enclosure systems. It is a proven alternative to 1- and 2-hour fire resistant shaft enclosures for grease ducts. 3M Fire Barrier Duct Wrap 615+ performs in temperatures up to 2192°F/1200°C. 3M Fire Barrier Duct Wrap 615+ is the only fire-rated duct wrap product you'll ever need to help protect both grease ducts and air ducts while passing the necessary fire tests to achieve up to 2-hour fire-resistance requirements. It is listed by California State Fire Marshall.
