Big Bubble Duct Insulation R‑6.0

The Reflectix® R-6.0 Duct Insulation is a nominal 1” thick and consists of two outer reflective surfaces that enclose a center layer of polyethylene big bubbles. The product has printed code certification that runs the length of the roll. The printed information includes R-value, ASTM numbers, manufacturer’s name and testing.

Round or Rectangular Ducts

• Make sure all metal joints, seams and penetrations are sealed.
• Verify circumference of the duct.
• Rectangular Duct: Cut the Reflectix® product to this length plus the width of the top panel of the duct.
• Round Duct: Cut the Reflectix® product to this length plus an additional 25% in length.
• Wrap the product around the duct and overlap the top panel (rectangular) or upper 25% (round) of the duct.
• Securely tape the linear and circumference seams with a UL 181 approved 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.

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. The correct construction methods and techniques are the responsibility of the installer or contractor. The methods outlined are recommendations on location of the Reflectix® products as a guideline. There are no claims on the part of Reflectix, Inc. that these building assemblies are finite standards or meet building code requirements (as they can vary by region).
