3M Fire Barrier Duct Wrap 615+

3M Company, well known for its vast portfolio of fire protection products, introduces 3M Fire Barrier Duct Wrap 615+, a new fire-resistant wrap that is lighter and thinner than previous 3M offerings and meets the new ASTM E 2336 fire test requirements. ASTM E 2336 is the fire test standard referenced in the 2009 Edition of the International Mechanical Code and the 2008 Edition of NFPA 96 ‘Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations’. Made from an advanced ceramic fiber wrapped in scrim-enforced foil, 3M Fire Barrier Duct Wrap 615+ is a lightweight, thin-profile insulation product that provides up to two hours of fire protection for grease and air ventilation ducts.

“3M Fire Barrier Duct Wrap 615+ is the newest innovation in 3M’s fire rated duct wrap line. It was developed specifically to meet the new ASTM E 2336 test standards, but also with the installer’s needs in mind. To maximize productivity, the installer wants the wrap to be lightweight, flexible and thin. In addition, to make installation as simple and easy as possible, contractors want one product for use in both grease and air duct applications,” says Jenny Hicks, Marketing Manager, Fire Protection Products with 3M Building and Commercial Services Division.

“3M Fire Barrier Duct Wrap 615+ installed around ducts creates a fire-resistive barrier that maintains the duct integrity and helps prevent fire from rapidly spreading throughout a building. The severity of the ASTM E 2336 standard leads to the requirement that two layers of fire protection material are necessary around grease ducts in jurisdictions that have adopted the 2009 Edition of the IMC or the 2008 Edition of NFPA 96,” says Mark Lund, P.E. (mechanical, fire protection), technical service engineer with 3M Building and Commercial Services Division. “The new lighter-weight product makes that two-layer installation process easier. Fire barrier wrap products from 3M are a smart, trusted alternative to conventional gypsum wallboard shafts, and other bulky and stiff wrap systems that take up a lot of space and are heavy and difficult to install. 3M’s newest product, 3M Fire Barrier Duct Wrap 615+, weighs only six pounds per cubic foot, about two pcf lighter than previous wraps so it is even easier to use.”

Advantages of new 3M Fire Barrier Duct Wrap 615+ include:

• Lighter weight and high flexibility for easier installation

• Low thermal conductivity

• Supports maximum temperatures of up to 2192°F (1200°C)

• Thermal shock resistant

• Monolithic blanket – foil encapsulated for blanket protection means less dust and high wrap strength

• Tested to ASTM standard E 2236 – grease duct standard

• Tested to ISO 6944 air duct standard

Because 3M’s newest duct wrap is thinner and lighter, 3M Fire Barrier Duct Wrap 615+ is beneficial from the start of the building process all the way to the finish; it helps architects and designers, contractors, building owners, as well as building inspectors. 3M Fire Barrier Duct Wrap 615+ can expand architectural design options and increases contractors’ productivity, it is designed to increase building owners’ and inspectors’ confidence by using tested systems that meet code.

Jenny Hicks goes on to say, “3M is a fire protection industry leader because our products help make the design, installation and code approval processes faster and easier. Customers rely on us because we offer a complete portfolio of fire protection products and accessories. Today’s total fire protection applications require both duct wrap and sealants and 3M is one of the only manufactures that offers both the wrap and the sealant. It’s becoming more and more common for contractors to ask architects to spec 3M products in their plans.”
