Blower doors are devices that are used to measure the air infiltration rate of homes and buildings. They use a large fan to depressurize the inside of the building, and then a digital monometer to measure the difference in air pressure between the inside and outside of the structure, which is then computed into an air flow rate in CFM (cubic feet per minute). Using a a blower door we can identify sources of air infiltration inside a home and also perform test-in and test-out measurements that allow us to demonstrate the exact extent that we have reduced the air infiltration rate of a home.
