C. Sealing at the Penetration of Building
Envelope
Envelope
The fi rst step for successfully creating an air barrier system is to seal all of the holes in the building envelope. Too
often, builders concentrate on air leakage through windows, doors, and walls, and ignore areas of much greater
importance. A key source of leakage—called a bypass—is hidden from view behind chases for fl ues and ductwork. It
is important to make sure these areas are sealed to prevent leakage. A common way to seal areas behind chases for
fl ues and ductwork is to attach and caulk a piece of plywood or foam sheathing material that covers the entire opening.
Seal penetrations. If a fl ue requires a noncombustible clearance, use a noncombustible metal collar, sealed in place to
span the gap.

Sealing these bypasses is critical to reducing air leakage in a home and maintaining the performance of insulation materials.
