Radiant Barrier

Reflectix® products are an excellent, energy-efficient choice for upgrading your attic system. When installed properly, a reduction of up to 10% in the home’s air conditioning usage can result. The products are clean, lightweight and easy to install. Additionally, attic-mounted HVAC ducts benefit from the reduction of attic surface temperatures.

Reflective/Scrim Radiant Barrier
Installation Instructions: (There are 3 options)

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

1. Underside of Rafter Method (depicted in illustration above)

• Check the attic area and make any needed repairs before installing Reflectix®.
• Unroll the Reflectix® as you work and cut it to suitable lengths (8’ to 12’) with scissors or utility knife.
• Allow for proper ventilation. See note below on ventilation.
• Install product perpendicular to the rafters with a 2” overlap on the seams (no taping required). Staple the product to the rafters at 2” to 3” intervals.
• Leave a 2” to 3” gap on each side of the roof peak and a gap at the lower edge of the roof line (within 18” OK).
• Staple to the face of the studs on gables and insure at least a 1” gap around all vents.

2. Staple to the Deck Method - Southern Zone of the USA Only
For the Regional Recommendation for the Staple to the Deck Method, please verify the location of your home with the “Zip Code Zone Locator” function below.


• Cut the entire roll of product into 16” or 24” lengths with a miter saw (depending on rafter spacing).
• Begin at the top of the cavity. Run product flush to the decking, parallel to the rafter.
• Staple sheet directly to the deck (Nails poking through sheet from above will not interfere with performance).
• Do not block any venting (cut around).
• No need to cover rafters (no loop around).

3. Ceiling Joist Application (Blanket Fashion)
Only the Reflective/Scrim/Reflective Radiant Barrier product can be installed in this manner. The product must be perforated to accommodate moisture transmission.
• Note: Dust accumulation on the product detracts from benefits. Dust (this application only) must be removed periodically to maintain effectiveness.
• Cut product into 8’ to 12’ sections.
• Lay directly over the top of the ceiling joists.
• Cut openings in the product above any heat generating devices (ex: light mounted in ceiling).
• Overlap seams 2”. Drape over any ducts close to the attic floor.
• Cut around truss work as necessary.


Reflective/Bubble Insulation
Installation Instructions: (There are 3 options)


1. Underside of Rafter Method (depicted in illustration above)

• Check the attic area and make any needed repairs before installing Reflectix®.
• Unroll the Reflectix® as you work and cut it to suitable lengths (8’ to 12’) with scissors or utility knife.
• Allow for proper ventilation. See note below on ventilation.
• Install product perpendicular to the rafters with a 2” overlap on the seams (no taping required). Staple the product to the rafters at 2” to 3” intervals.
• Leave a 2” to 3” gap on each side of the roof peak and a gap at the lower edge of the roof line (within 18” OK).
• Staple to the face of the studs on gables and insure at least a 1” gap around all vents.

2. Staple to the Deck Method - Southern Zone of the USA Only
For the Regional Recommendation for the Staple to the Deck Method, please verify the location of your home with the “Zip Code Zone Locator” function below.


• It is easiest to install either 16” or 24” wide product (depending on rafter spacing).
• Begin at the top of the cavity. Run product flush to the decking, parallel to the rafter.
• Staple sheet directly to the deck (Nails poking through sheet from above will not interfere with performance).
• Do not block any venting (cut around).
• No need to cover rafters (no loop around).

3. Truss Cavity or Side of Rafter Method
• Utilize either 16” or 24” Reflective/Bubble product (depending on truss/rafter spacing).
• Product will be installed parallel to the truss/rafter direction.
• Begin at the top of the cavity.
• Staple the product (either Staple Tab (ST Reflective/Bubble) or the edge of the BP Reflective/Bubble product) to the side of the top chord of the truss (the structural 2”x 4” (or 2”x 6”) that is attached to the roof decking) or the side of the rafter.
• Continue down length of truss/rafter stapling at 2” to 3” intervals - Repeat on opposite truss/rafter.
• Allow for proper ventilation. See note below on ventilation.
• A minimum of a 1/4” continuous air gap should be present between the product and the roof decking - Do not staple the product directly to the deck - This product is not perforated and could potentially condensate.
• Do not block any venting (cut around).

Ceiling Joist Application (Blanket Fashion):
The Reflective/Bubble product should not be installed in this manner. Only perforated products like the Reflective/Scrim/Reflective Product should be installed in this fashion.

Ventilation:
Good ventilation in the attic increases the home's comfort level and helps the materials of the house last longer. Be sure not to block any ventilation paths when the Reflectix® is installed.
