Blower Door & Air Permeability Testing

Airtightness is vital to creating healthy, comfortable draft free energy efficient buildings. A Blower Door is a machine used to measure the airtightness of buildings. It can also be used to measure airflow between building zones, to test ductwork airtightness and to help physically locate air leakage sites in the building envelope.
