TABLE N1102.4.2
AIR BARRIER INSPECTION
COMPONENT CRITERIA
Ceiling/attic Sealants or gaskets provide a continuous air barrier system joining the top plate of framed walls with either the ceiling drywall or the top edge of wall drywall to prevent air leakage.

Top plate penetrations are sealed.

For ceiling finishes that are not air barrier systems such as tongue-and-groove planks, air barrier systems, (for example, taped house wrap), shall be used above the finish.

Note: It is acceptable that sealants or gaskets applied as part of the application of the drywall will not be observable by the code official.
Walls Sill plate is gasketed or sealed to subfloor or slab.
Windows and doors Space between window and exterior door jambs and framing is sealed.
Floors (including above-garage and cantilevered floors) Air barrier system is installed at any exposed edge of insulation.
Penetrations Utility penetrations through the building thermal envelope, including those for plumbing, electrical wiring, ductwork, security and fire alarm wiring, and control wiring, shall be sealed.
Garage separation Air sealing is provided between the garage and conditioned spaces. An air barrier system shall be installed between the ceiling system above the garage and the ceiling system of interior spaces.
Duct boots Sealing HVAC register boots and return boxes to subfloor or drywall.
Recessed lighting Recessed light fixtures are air tight, IC rated, and sealed to drywall.
     Exception—fixtures not penetrating the building envelope.
