About Air Infiltration

Definition: The uncontrolled leakage of air into a building through joints and gaps around the door and frame

Causes: Wind, stack pressure and mechanical equipment in the building (ex exhaust fan)

It Depends On: 

1. The characteristics of the door

2. The quality of the installation  “The highest performing products will not perform well if installed poorly” -Rich Rinka, technical manager, standards and industry affairs with the American Architectural Manufacturers Association.
