Air-Sealing Precautions:Checked by(print name)
Protect finish surfaces and concrete floors as needed
Protective gear: particle mask, disposable gloves required (see Note 1)
Air-Sealing Tasks Checked by(print name)
Use hi-temp 3M Fireblock (Home Dep.) to seal outside of J-boxes (No fire-block inside of boxes)
Seal all switch and plug boxes to drywall (Fireblock or latex caulk. After drywall install)
Air seal light boxes to drywall at ceiling.
Cover all holes in metal J-boxes with high-temp aluminum tape
Seal all holes in bath fan enclosures with hi-temp aluminum-butyl tape
Use hi-temp 3M Fireblock or fire-rated foam outside of J-boxes (Orange Great Stuff at HD or equivalent)
Air seal all plumbing holes in drywall around pipes under sinks
Air seal all plumbing penetrations at top plate
Air seal all electrical penetrations at top plate
Air seal all top plates at drywall (Joints between wood and drywall at tops of walls known to cause 2/3 leakage)
Where there is no attic access, seal drywall to top plate as it is installed on new construction
Seal drywall to bottm plate as drywall is installed on new construction
Seal bottom plate to slab or floor with caulk or use sill gasket (best practice on new construction)
Air seal skylight shafts
Air seal skylight tubes at attic side of drywall being sure not to glue the lens (removable for cleaning)
Make sure all open chases are sealed at ceiling plane. (Chase is a mech. syst. Cavity in wall assembly)
Air seal duct pass-throughs at drywall ceiling, range hood ducts, etc.
Air seal all duct registers to drywall penetrations (either using foam from the top, caulk or tape from bottom)
Air seal all knee walls/living space
Air seal all subfloor penetrations
NOTE 1: Urethane foams are toxic and absorb through skin. Exposure is associated with rashes and increased cancer rates.
the foam can outgas carcinogenic gasses over time, resulting possibly in structure being condemned.
NOTE 2: Do not tape or otherwise air seal at OSB sheathing plane. (Construction adhesive OK where required for shear) Sealing OSB is an unnecessary
additional expense and is not required to achieve tight building standard (ACH50=2.0-2.5), AND it inhibits drying through vapor permeable
water barriers such as Tyvek. We highly recommend use of rainscreen products in conjunction with exterior foam to allow wall assembly drying.
