3M Fire Barrier Duct Wrap 615+

Product Description, Applications

3M Fire Barrier Duct Wrap 615+ is a fire-resistant wrap with excellent insulating capabilities. A proven alternative to traditional rigid fire-rated shaft enclosures, this single-layer blanket wraps around the duct, maintaining the integrity of the duct, preventing fire from passing from compartment to compartment, and providing zero clearance to adjacent combustibles in the event of an internal grease fire.

3M Fire Barrier Duct Wrap 615+ is ideal for life safety system ducts and can be used to protect both grease and air ducts. It is suited for a variety of applications:

• Mechanical smoke exhaust
• Stairwell pressurization
• Ventilated vestibules
• Zoned smoke control
• Elevator smoke control
• Ducts crossing exit corridors
• Smokeproof enclosures with mechanical ventilation
• Engineered ventilation systems
• Dryer exhaust vents
• Toilet exhaust vents
