3M 7000059415 Fire Barrier Plenum Wrap 5A+ Roll

Product Description

The 3M 7000059415 is a fire barrier plenum wrap rated 5A+, designed to protect plastic pipes and plastic-sheathed cables routed through return air plenums. The wrap consists of a 0.5-inch-thick inorganic blanket encapsulated in a scrim-reinforced foil facing. When installed correctly around plastic penetrations, it creates a compliant enclosure that achieves acceptable smoke and flame spread ratings as required by mechanical and building codes. HVAC technicians, mechanical contractors, and fire-stop installers work with this product during new construction and renovation projects where plenum-rated protection is required.

This wrap is used in commercial and residential applications where plastic pipes or cables pass through or are located within return air plenums. Return air plenums are common above drop ceilings in commercial buildings and in air handler systems. The 5A+ rating makes it suitable for projects requiring demonstrated smoke and flame spread performance. Each roll measures 0.5 inches thick, 48 inches wide, and 25 feet long, providing substantial coverage per unit.

Key Features

• 0.5-inch-thick inorganic blanket construction provides a fire-resistant thermal and smoke barrier
• Scrim-reinforced foil encapsulation protects the blanket core and aids in handling and installation
• 5A+ rating meets code requirements for plastic pipe and cable protection in return air plenums
• 48-inch width accommodates a range of pipe diameters and cable bundle sizes in a single wrap
• 25-foot roll format reduces material handling and cuts waste on larger jobs
• Weighs 18.53 pounds per roll, manageable for single-technician overhead installation

Compatibility

Designed for use around plastic pipes and plastic-sheathed cables installed within return air plenums where applicable building and mechanical codes require smoke and flame spread protection.

Installation Notes

Installation is typically performed by licensed mechanical contractors or certified fire-stop installers in accordance with the International Mechanical Code and applicable local building codes. Shut down the air handling system before working in the plenum space to prevent debris contamination and to comply with safe work practices. Follow the manufacturer installation instructions for overlap, fastening, and sealing requirements to maintain the rated assembly. Do not compress the blanket core beyond specified limits, as deformation can reduce thermal performance.
