Installation Instructions: There are 2 options.
Note
:
Installation instructions and illustrated drawings are recommendations only, while proper local construction methods are the responsibility of the installer.


1. Standard Wrap (Circumference) - Round or Rectangular Ducts
• Make sure all metal joints, seams and penetrations are sealed.
• Verify circumference of the duct.
• Cut the Reflectix® product to this length plus 1”.
• Wrap the product around the duct and securely tape the linear and circumference seams (overlapping 1”- 2”) with UL 181 Acrylic Adhesive Foil Tape (goal is an air-tight, snug seam seal). Do not leave any exposed duct or space where air can enter between the duct and the Reflectix®.

2. Spiral Wrap Directly Against Duct - Round Ducts
• Make sure all metal joints, seams and penetrations are sealed.
• Spiral wrap Reflectix® around the duct, overlapping 2” as you proceed.
• If necessary, trim width of product to accommodate bends or diameter changes in the duct.
• Securely tape seams with UL 181 Acrylic Adhesive Foil Tape (goal is an air-tight, snug seam seal).
• Do not leave any exposed duct or space where air can enter between the duct and the Reflectix®.

Please Note Regarding Hangers:
Strap Hanger: Wrap Reflectix® with the seam at the hanger. Tape seam tightly around hanger.
Saddle Hanger: Make sure that there is a spacer below the hanger, between the insulation and the duct, to prevent the insulation from touching the duct.
