Reflectix Inc DW1202504 Duct Wrap Insulation 12x25 R-4

Product Description

The REFLECTIX INC DW1202504 is a reflective spiral duct wrap insulation designed for wrapping round spiral duct, pipes, and similar HVAC components. Constructed with foil on both sides, it provides an R-value of 4.0, reducing heat loss from ductwork in unconditioned spaces such as attics, crawlspaces, and mechanical rooms. Each roll measures 12 inches wide by 25 feet long, giving installers a manageable format for fieldwork. HVAC technicians and insulation contractors install this product as part of duct sealing and insulation assemblies to improve system efficiency and maintain conditioned air temperatures across distribution runs.

This duct wrap is suited for residential and light commercial HVAC installations where spiral or round duct runs through unconditioned areas. The standard-edge design allows a simple spiral wrap technique around the duct or pipe, lapping each pass by approximately 0.5 inches to maintain consistent coverage. Once wrapped, the material is secured with foil tape to complete the thermal and radiant barrier. It is commonly applied during new construction duct installation or as part of an energy retrofit on existing systems.

Key Features

• R-value of 4.0 for effective thermal resistance on duct and pipe surfaces
• Foil facing on both sides provides a radiant barrier that reflects heat away from the duct surface
• 12-inch width and 25-foot length per roll suits standard spiral duct diameters
• Standard-edge design enables straightforward spiral wrap application with a 0.5-inch lap
• Lightweight at 6 pounds per roll for easy handling on ladders and in confined spaces
• Secure with compatible foil tape after wrapping to complete the installation

Compatibility

Designed as an OEM-style replacement and standard-use insulation wrap for residential and light commercial round spiral duct and pipe insulation applications.

Installation Notes

Installation is typically performed by licensed HVAC technicians or insulation contractors. Power down the air handling system before working on duct runs to avoid air pressure interference during wrapping. Spiral the wrap around the duct with each pass overlapping by 0.5 inches, then secure all edges and seams with foil-backed tape rated for duct insulation service. Follow local energy codes and ACCA or ASHRAE duct insulation guidelines for minimum R-value requirements in your climate zone.
