Door & delivery bay air leakage

Doors and delivery bays are another key sources of air leakage. Cosmetic finishes around doors can give the illusion of air tightness. However, assessments using a blower door, tracer gas, and thermal imaging testing demonstrate otherwise.

Delivery bays are often an overlooked area of a building’s air barrier. Under positive and negative air pressure, air leakage through delivery bays is amplified.
