Attic Insulation

Attic Insulation: Radiant Barrier, 2 Options / Reflective Bubble, 3 Options

Installation Instructions

Reflective/Woven Fabric Radiant Barrier Installation Instructions: (There are 2 options)

1. Underside of Rafter Method (depicted in illustration)

  • Check the attic area and make any needed repairs before installing InfraStop®.

  • Unroll the InfraStop® as you work and cut it to suitable lengths (8’ to 12’) with scissors or utility knife.

  • If a helper is available, rolling out longer lengths of product with one person stapling and the other holding the end of the product makes for a quicker installation.

  • Allow for proper ventilation. See note below on ventilation.

  • 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 depending on roof pitch).

  • 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 USA ONLY

  • 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.

  • The Staple Tab product is the easiest to work with for this application (but the Standard Edge product is equally effective).

  • 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).

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

1. Underside of Rafter Method (depicted in illustration)

  • Check the attic area and make any needed repairs before installing InfraStop®.

  • Unroll the InfraStop® as you work and cut it to suitable lengths (8’ to 12’) with scissors or utility knife.

  • If a helper is available, rolling out longer lengths of product with one person stapling and the other holding the end of the product makes for a quicker installation.

  • 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 depending on roof pitch).

  • 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

  • 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” double bubble insulation (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 (ISST Reflective/Bubble) or the edge of the ISFDF 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).

Ventilation: Good ventilation in your attic increases your comfort and helps the materials of your house last longer. Be sure not to block ventilation paths when you install InfraStop®.
