Thin, lightweight and flexible, 3M™ Fire Barrier Duct Wrap 615 provides excellent insulating capabilities and is a space-saving alternative to traditional, fire-rated gypsum shaft enclosures. It provides up to two-hour fire-resistance ratings for air distribution duct systems, meeting code and fire protection requirements.

3M™ Fire Barrier Duct Wrap 615 is a single layer flexible duct wrap enclosure for 1- and 2-hour fire-rated air distribution systems. It consists of an inorganic, non-asbestos fibre blanket encapsulated with a scrim-reinforced foil. This wrap installs easily due to its high flexibility, low weight and thin profile, making it an ideal choice for ventilation duct enclosure systems. It also serves as protection for standipe system piping, when installed in locations where a rating is required. 3M™ Fire Barrier Duct Wrap 615 performs in temperatures up to 1200°C (2192°F). It is third party certified - via ULC and Intertek - to ISO 6944 (Fire containment - Elements of building construction - Part 1: Ventilation ducts), resulting in competitive systems for the Canadian market: FRD-17, FRD-23, FRD-27 and 3MU/DI 60-01, 3MU/DI 120-01.

Suggested Applications

  • Air distribution systems
  • Stairwell and vestibule pressurization, smoke exhaust, laboratory chemical fume and commercial dryer ducts as well as sprinkler standpipes, refuse and linen chutes.
