Attic Radiant Barrier - Extra Touches that Provide Extra Efficiency

Butt insulation against chimney and friction fit around lighting fixtures, exhaust fans, motors or vents extending into attic. Cover and/or butt insulation against these objects only as manufacturer permits.

Eliminate cold spots by filling cracks around doors and window framing with Astro-Foil.   Bow in and staple or tape to wood.

Small punctures do not require repair.  Large rips or tears should be patched with pressure-sensitive aluminum tape before installation of wall finishing.

To prevent condensation in the attic, it helps to keep air moving out through eave vents, openings under the eaves, gable vents and roof vents.  Provide one square foot of free vent area for each 300 square feet of attic floor area.  PROPER INSTALLATION OF ASTRO-FOIL SHOULD NOT BLOCK PROPER VENTILATION.

Insulate pull-down stairways by stapling Astro-Foil to a built-up frame work.   Also staple on scuttle hole boards.

Butt ALL seams and tape with 2" wide pressure sensitive aluminum tape.   DO NOT USE DUCT TAPE.  Make sure tape and insulation are clean, dry and applied in an environment above 40`F.  Tape only to seal seams.  Do not use to secure insulation itself.  Apply tape over seams evenly and use a wider width if necessary.  Scrape a squeegee over the tape several times to remove air pockets.
