3M™ Fire Barrier Duct Wrap 615 is designed for the protection of ventilation ducts as a shaft alternative.
Ventilation ducts that are required to be protected are those that have to do with maintaining life-safety in a building, and are typically damper-less ducts.
Examples of ventilation ducts required to be protected:
▪ Stair pressurization ducts for smoke-proof enclosure systems
▪ Life safety ducts feeding critical care areas (surgery rooms, neo-natal, recovery rooms)
▪ Ducts crossing exit corridors

A 1.5" thick fire resistant wrap consisting of a calcium-, silica-, and magnesium-oxide fiber blanket encapsulated with a scrim-reinforced foil. Used to create a fire-resistive enclosure around ventilation ducts, including life safety systems like stair pressurization and smoke exhuast ducts.
