Manufactured by 3M, Fire Barrier Duct Wrap 615+ is a high performance fire protection solution engineered to help contain fire within duct systems. It is specifically designed for grease ducts and air ventilation ducts that require fire resistance ratings without the need for bulky shaft enclosures. This wrap system helps maintain code compliance while simplifying installation and reducing structural requirements.
The duct wrap is lightweight and thin, making it easier to handle and install compared to traditional fire rated enclosures. In 2 layer grease duct applications, the inner layer is butted to ensure proper coverage and performance. Its flexible design allows for custom installation configurations, including multiple layers where higher fire ratings are required.
One of its key advantages is zero clearance to combustible materials throughout the entire enclosure system, allowing ducts to be installed in tighter spaces without additional framing. This makes it ideal for commercial kitchens, high rise buildings, industrial facilities, and other projects where space efficiency and fire safety are critical.
