Advanced Firestopping Technology

Safeguard air and grease ductwork, electrical circuitry and other components behind walls with the advanced firestopping technology of 3M's protective wrap systems.


Protective Wrap Systems

  • Rigorously Tested Solutions

    There's a protective wrap system for every need. Lightweight, flexible 3M™ Fire Barrier Duct Wrap 615+ protects both air and grease ducts for up to two hours. 3M™ Fire Barrier Plenum Wrap 5A+ creates a fire-resistive enclosure that can reduce flame and smoke spread ratings to acceptable levels. For additional protection, 3M™ Interam™ Endothermic Mat uses chemically bound water to slow heat transfer. All are rigorously tested and easy to install, for fire protection solutions you can stand behind.


Protective Wrap Products

  • Flexible 3M™ Interam™ Endothermic Mat (E-Mat) installs quickly and easily, even on complex shapes. In the event of a fire, it releases chemically bound water to cool outer surfaces and significantly slow heat transfer, protecting structural steel components for up to four hours, critical electrical components for up to three and wall opening membranes for up to two. Once installed, E-Mat offers low cost of ownership and is easy to maintain and inspect.

  • This is a proven alternative to 1- and 2-hour fire-resistant rated shaft enclosures when you need to protect grease ducts. It consists of a non-asbestos inorganic fiber blanket adhered to a scrim-reinforced foil for protection and stability. The wrap is thin and lightweight for easy, space-saving installation, yet also allows custom installation applications with multiple layers.

  • This strong yet flexible fire-resistant wrap is used to create a fire-resistive enclosure that can reduce flame and smoke spread ratings to acceptable levels in return air plenums. The lightweight material consists of a non-asbestos inorganic fiber blanket encapsulated with a scrim-reinforced foil and is extremely easy to manipulate and install, particularly around pipes and cabling.
