There are 2 Installation Options

 1. Standard Wrap (Reflective/Bubble/Bubble/Reflective – Roll product)

• 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 a UL 181 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 (Reflective/Bubble/Bubble/Reflective, Duct Insulation – Roll product)

• 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 a UL 181 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

Review These Important Safety Guidelines Prior to Installation:

• ALWAYS check local building codes before installing Reflectix®.
• ALWAYS check the area you are insulating and make any needed repairs. Any worn wiring should be replaced before you begin installing Reflectix®.
• ALWAYS make sure work areas are well ventilated and well lighted.
• ALWAYS use eye protection when operating a staple gun.
• ALWAYS use caution and common sense when using a staple gun. Be aware of electrical wiring locations. Stapling into a wire can cause severe shock or death. NEVER staple into electrical wiring.
• ALWAYS be careful when working with large pieces of Reflectix® on windy days.
• When installing Reflectix® on bright sunny days, it is best to wear sun glasses.
• Do not work in areas such as attics when temperatures are too hot.
• Please Note: The intention of these Installation Instructions and 3-D renderings are for the sole purpose of illustrating the correct location and relative position of the Reflectix® products in specific building assemblies.
