Reflectix is proud to announce the introduction of a new and innovative design in Duct Insulation; the Reflectix® R-8.0 Fiber Duct Insulation. This product combines the “Easy to Handle and No Itch” characteristics of our other products with the enhanced thermal performance of R-8.0. A reduction in labor costs due to easier installation and handling make Reflectix® your product of choice when you are considering your duct insulation options.

Product Description

Reflectix® R-8.0 is a 1” thick insulation with an outer 96% reflective surface, a 1” polyester center, and another outer 96% reflective surface. It is extra tough, does not itch and is thinner than R-8.0 fiberglass wraps. The product is lightweight and has 2 vapor barriers to help inhibit condensation. A code identification tape runs the length of the roll listing ASTM numbers, the manufacturer’s name and testing information.

Benefits

  • Reduces overall thickness of conventional R-8.0 wrap (3” to 1.25”)
  • Inhibits condensation on duct work
  • Reduces overall heat loss or gain
  • Does not itch
  • Easy to install
  • Reduces heat loss in the winter and heat gain in the summer
  • Requires less space than fiberglass to achieve R-8.0 (with 0.75” air space)
  • Inhibits condensation
  • Resists growth of fungi, mold and mildew
  • Class A / Class 1 Fire Rating

Installation Instructions

There are 2 options depending on the type of spacer. Method 1 is applicable to either round or rectangular ducts. Method 2 applies to rectangular ducts only.

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

Note: Either spacing method is approved.

1. 2” Wide Spacer

  • Make sure the duct is free from dust and dirt by wiping it down with a shop rag.
  • Make sure all sheet metal joints, seams and penetrations are sealed.
  • Wrap the duct in a big looping fashion down one direction of the duct and then back (criss-crossing candy cane pattern). The crossing loops create a 0.75” enclosed air space between the duct and the wrap.
  • Or, secure spacer (double layered) every 24” to 36” around ducting, fastening the spacers with a UL 181 approved tape.
  • 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 foil from touching the duct.
  • Tape all seams with a UL 181 approved tape.

2. HV Plastic Spacer (Rectangular Ducts Only)

  • Make sure the duct is free from dust and dirt by wiping it down with a shop rag.
  • Make sure all sheet metal joints, seams and penetrations are sealed.
  • Install the spacers every 24” to 26” apart on all four corners of the duct.
  • Wrap the insulation over the spacers.
  • Fasten the Reflectix® by either tapping the seam or plier stapling the two edges together.
  • If the duct is supported with saddle clamps, make sure to install a spacer on the two bottom edges of the duct directly between the clamp and the duct.
  • If the clamps are installed around the duct (such as plumbers tape), make sure that the seam is taped to prevent air movement.

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.

Important

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).
