Blower Door

A blower door is simply a fan with a pressure gauge. It is attached inside of a doorway. A blower door is a machine used to measure the air tightness of buildings. It can also be used to measure airflow between building zones, to test duct work air tightness and to help physically locate air leakage sites in the building envelope.

It is a new home builders most important diagnostic tool. Results from this test places a number on a home's performance relating to energy and comfort. This is the most critical aspect of a building envelope. Results can have a big impact on Indoor Air Quality IAQ. Call us today to set an appointment for a Blower Door Test! (218) 722-9003

 

How They Work

A blower door is a powerful fan that mounts into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings. The auditors may use a smoke pencil to detect air leaks. These tests determine the air infiltration rate of a building.

Blower doors consist of a frame and flexible panel that fit in a doorway, a variable-speed fan, a pressure gauge to measure the pressure differences inside and outside the home, and an airflow manometer and hoses for measuring airflow.
