Smart solution addressing a variety of application needs including air ducts, grease ducts, and chemical exhaust ducts. Manufactured with a man-made vitreous spun fibre, which provides low thermal transfer properties in a lightweight, low profile, easy to apply product . The insulative properties of Duct Wrap help keep heat, fire and smoke contained.

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™ aluminium 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).
