R-8.0 Bubble Insulation
Installation Instructions:
(There are 3 options)
Methods 1 & 2 are applicable to either round or rectangular ducts.

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 on page 2. 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 UL 181 Acrylic Adhesive Foil 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 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. 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 on page 2. 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 UL 181 Acrylic Adhesive Foil 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 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®.

3. HV Spacers Affixed to Corners Method (Rectangular Ducts Only)
Spacer: HVSPACER - Reflectix® Hard Plastic Corner Spacer

• Refer to the lower two diagrams on page 2. 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 36” apart. 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 UL 181 Acrylic Adhesive Foil 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.



R-8.0 Fiber Wrap Insulation

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 UL181 approved foil 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 UL181 approved foil 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.
