Quietflex dwr62248075 Duct Wrap R-6.5 48in X 75ft

Product Description

The QUIETFLEX dwr62248075 is a fiberglass duct wrap insulation blanket in the EQ FRK Series, engineered for wrapping rectangular and round sheet metal ductwork in HVAC distribution systems. At 2.2 inches thick, it achieves an R-6.5 thermal rating and carries a temperature rating of up to 250 degrees F, making it suitable for both supply and return air applications in heated or cooled systems. The foil-reinforced kraft (FRK) facing provides a vapor barrier and a staple-able, tapeable surface. This product is installed by HVAC mechanics and sheet metal contractors during new construction and retrofit duct insulation work.

This duct wrap is used on exposed ductwork in unconditioned spaces such as attics, crawlspaces, basements, and mechanical rooms where thermal loss or gain must be controlled. The 48-inch width accommodates a wide range of duct sizes without excessive overlap waste, and the 75-foot roll length covers substantial duct runs in a single roll. It is appropriate for residential and light commercial HVAC applications where an R-6.5 insulation value is required by energy code.

Key Features

• R-6.5 thermal resistance at 2.2 inches thickness
• Temperature rated to 250 degrees F for compatibility with supply air duct systems
• FRK facing serves as an integrated vapor retarder and provides a surface for mechanical fastening or foil tape
• 48-inch width suits a broad range of duct dimensions and reduces field cutting
• 75-foot roll length minimizes seams on long duct runs
• Fiberglass construction resists moisture degradation and does not support mold growth

Compatibility

Designed as an OEM-style duct insulation wrap for use on rectangular, round, and oval sheet metal ductwork in residential and light commercial forced-air HVAC systems requiring R-6.5 insulation.

Installation Notes

Shut down the air handling unit and allow ductwork to reach ambient temperature before wrapping. HVAC mechanics should secure the FRK facing with outward-clinching staples and seal all seams and penetrations with listed foil tape per SMACNA guidelines and applicable energy codes. Wear appropriate personal protective equipment, including gloves and eye protection, when handling fiberglass insulation. Do not compress the insulation during installation, as compression reduces the effective R-value.
