R-6.0

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

Reflectix® Duct Insulation is an alternative to other types of fibrous insulation products. Ease of handling and quick installation make Reflectix® the first choice when selecting insulation for round or rectangular ductwork in HVAC systems. The product provides an R-6.0 when installed with a 0.75” air gap between the duct and the insulation. There is a choice of three spacer configurations that create the required air space.

Product Description

Reflectix® Duct Insulation consists of two layers of highly reflective film (96% reflectivity) that are bonded to two tough layers of polyethylene. Two inner layers of insulating bubbles resist conductive heat flow while a center layer of polyethylene gives Reflectix® high reliability and strength. The product has a tape running the length of the roll for easy identification by code officials. The tape identifies the manufacturer and ASTM Testing: Reflectix® Duct Insulation • ASTM E84 • Class A / Class 1 • ASTM C411 Passed

Installation Instructions

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

1. Spacer Perpendicular to Duct Direction Method

Spacer: HVSPW02025 – Reflectix® Spiral Pipe Wrap 2”x 25’

  • Refer to the top two diagrams above.
  • Make sure all sheet metal joints, seams and penetrations are sealed.
  • Double wrap and secure spacer material to the duct at 24” to 36” intervals. Use a UL 181 approved tape to fasten the spacer in place.
  • Verify the circumference of the duct at the mid-point of a spacer strip.
  • 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 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®.

2. Spacer Wrapped in Candy Cane Fashion Method

Spacer: HVSPW02025 – Reflectix® Spiral Pipe Wrap 2”x 25’

  • Refer to the third and fourth (from the top) diagrams above.
  • Make sure all sheet metal joints, seams and penetrations are sealed.
  • Double wrap and secure spacer material to the duct in a candy cane fashion. First, proceed down the duct in one direction then reverse direction and crisscross (overlap) the spacer in the other direction. Use a UL 181 approved tape to fasten the spacer in place.
  • Verify the circumference of the duct with the spacer strips in place.
  • 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 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®.

3. HV Spacers Affixed to Corners Method (Rectangular Ducts Only)

Spacer: HVSpacer – Reflectix® Hard Plastic Corner Spacer

  • Refer to the lower two diagrams above.
  • Make sure all sheet metal joints, seams and penetrations are sealed.
  • Make sure the duct is free from dust and dirt by wiping it down with a shop rag.
  • Install the HV Spacers to all 4 corners of the duct.
  • Place the spacers every 24”.
  • Verify the circumference of the duct over the top of the spacers.
  • Cut the Reflectix® product to this length plus 1”.
  • Wrap the Reflectix® over the spacers.
  • Fasten the Reflectix® by either taping the seam with a UL 181 approved tape, or plier stapling the two edges together (goal is an air-tight, snug seam seal).
  • 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).
