Foil-encapsulated, non-combustible, flexible, fire-resistive wraps for grease ducts, air ducts and plenum air spaces.
The 3M line of products consists of duct wrap and plenum wrap. Both products are completely foil-encapsulated. The duct wrap is used for commercial kitchen exhaust grease ducts, fire rated air ventilation exhaust ducts, chemical exhaust ducts and stair pressurization ducts. The plenum wrap product is a high temperature insulation blanket that is used to create an enclosure with low flame and smoke spread ratings around cables and pipes in return air plenums.
