3M™ Fire Barrier Duct Wrap 615

Product Description:

3M™ Fire Barrier Duct Wrap 615 is a fire resistant wrap consisting of a bio-soluble ceramic fiber blanket encapsulated with a  scrim-reinforced foil. As a single layer fire resistant wrap, it has passed ISO 6944 ‘Fire Resistance Tests – Ventilation Ducts’. This non-asbestos wrap contains a safer fiber construction and installs easily because of its high flexibility and strength. With its excellent insulating capabilities, low weight and thin profile, it is an ideal choice for a duct enclosure system.



  • One layer wrap for ventilation ducts
  • High flexibility for installation ease
  • Thin and lightweight
  • Nominal 6pcf density
  • Foil encapsulated for blanket protection, less dust and high wrap strength
  • Center stitched for ease of handling and banding location
  • Safer fiber construction


3M™ Fire Barrier Duct Wrap 615 is an ideal fire resistive enclosure  for life safety system ducts. These duct systems are in place to allow occupants to safely leave a building in fire scenario. Dampers are frequently omitted from life safety ducts. 3M™ Fire Barrier Duct Wrap 615 installed around the duct creates a fire-resistive enclosure that maintains the integrity of the duct and prevents the passage of fire from one compartment to the next. Compared to conventional gypsum enclosures, 3M™ Fire Barrier Duct Wrap 615 is lighter weight, requires less space and typically has lower installation costs. It is a proven alternative to a 1- or 2-hour fire resistant rated shaft enclosure in protecting ventilation ducts as tested per ISO 6944-85 ‘Fire Resistance Tests – Ventilation Ducts’.

Some smoke-control methods commonly used to achieve life safety objectives are:

  • Mechanical Smoke Exhaust
  • Stairwell Pressurization
  • Ventilated Vestibules
  • Zoned Smoke Control
  • Elevator Smoke Control
  • Smokeproof Enclosures with Mechanical Ventilation
  • Engineered Ventilation Systems
