The 3M™ Fire Barrier Duct Wrap 615+ provides excellent insulating capabilities and offers a space-saving alternative to traditional bulky fire protection methods obtained through a gypsum wall shaft or enclosure. 3M™ Fire Barrier Duct Wrap 615+ is composed of thin, lightweight material and is commonly used in commercial kitchen grease ducts and ventilation ducts.3M Fire Barrier Duct Wrap 615+ is a fire-resistant wrap consisting of an inorganic fibre blanket encapsulated with a scrim-reinforced foil. The blanket adheres to the foil scrim on the 3M Fire Barrier Duct Wrap 615+, which helps prevent wrapping and slumping before and after application. 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. The 3M Fire Barrier Duct Wrap 615+ performs in temperatures up to 2192F (1200C) and provides fire-resistant protection for up to two hours!
