Blower door test

Blower door test

A powerful fan mounts into the frame of an exterior door and pulls air out of the house, lowering the air pressure inside. Outside air then flows in through all unsealed cracks and openings. By measuring the force needed to maintain a certain pressure difference, a measure of the home’s air-tightness can be determined.
