About:

Definition:

AIR EXFILTRATION

• The uncontrolled outward leakage of indoor air through cracks, discontinuities and other unintentional openings 
in the building envelope.
• In winter the air is likely to be heated, and heated air exfiltration will result in uncontrolled heat loss and potential interstitial condensation risk.
