3M has developed 3M™ Fire Barrier Duct Wrap 615+ to be the only fire-rated duct wrap product youll need to help protect both grease ducts and air ducts, in an easy to install format (lightweight, flexible) while passing the necessary fire tests to achieve up to 2-hour fire-resistance requirements. Use 3M™ FSK Facing Tape 3320, 3M™ Aluminum Foil Tape 425 or similar system compatible heat-resistant tape to seal any cut edges of the duct wrap. When the duct penetrates through a fire-rated wall or floor assembly, it must be firestopped using a system-approved 3M™ Fire Barrier Sealant (check system details for approved sealants).
