Reflectix DW-48X75-BW-R8 Duct Wrap Insulation R-8.0

Product Description

The REFLECTIX DW-48X75-BW-R8 is a big-bubble foil duct wrap insulation rated at R-8.0, designed for wrapping rectangular and round ductwork in residential and light commercial HVAC systems. The foil facing reflects 97% of radiant heat when installed with an air space, which is required to achieve the stated R-8.0 thermal resistance. The product is fiber-free, making it clean to handle and cut during installation. Weighing 22 pounds for the full roll, it is lightweight relative to conventional duct insulation materials, reducing labor time on the job. HVAC technicians and insulation contractors are the primary installers.

This duct wrap is well suited for applications in unconditioned or semi-conditioned spaces where ductwork is exposed to extreme temperature swings, including attics, garages, crawlspaces, and mechanical rooms. The fiber-free, foil construction resists moisture absorption and does not support mold, fungi, or mildew growth, making it appropriate for high-humidity environments. It can be applied to both rectangular sheet metal duct and round spiral duct of standard residential and light commercial sizes.

• Compatible with rectangular and round ductwork configurations
• Lightweight roll simplifies cutting, handling, and overhead installation
• Made in the USA

Compatibility

Designed as an OEM-style duct wrap solution for rectangular and round HVAC ductwork in residential and light commercial applications where R-8.0 insulation is specified.

Installation Notes

Installation is typically performed by licensed HVAC technicians or insulation contractors following local energy codes and ACCA or SMACNA guidelines. The system should be shut down and de-energized before wrapping active ductwork sections. An air space must be maintained between the foil facing and the duct surface to achieve the rated R-8.0 value — installation without an air space will reduce effective thermal performance. Secure seams with foil tape rated for duct applications; do not use standard duct tape or staples that can compromise the vapor barrier.
