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.

• 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

• HVRP48050 (48”x 50’)
• HVRP48100 (48”x 100’)

Spacers:

• HVSP0202506
• HVSPACER

• Thickness: 1”
• Weight: 1.22 oz/sq. ft.
• Thermal Resistance (ASTM C 335): R-8 with 0.75” air space
• Flame & Smoke (ASTM E 84/UL723): Class A/Class 1
• Water Vapor Permeability (ASTM E96): <0.02 Perms
• Temperature Range (ASTM C 411): -50 F to 180 F
• Resistance to Fungi/Bacteria (ASTM C 1338): Does not promote growth
• Emissivity (ASTM C 1371): 0.04
• Reflectivity (ASTM C 1371): 96%

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.

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).
