                                      A BLOWER DOOR is a machine that is used to measure the airtightness of buildings.  It can also be used to                                              measure airflow between building zones and to help physically locate the air leakage sites in the building                                              envelope.

•                              There are three (3) primary components to a BLOWER DOOR:  (1) a calibrated variable-speed fan, (2) a                                             manometer that measures pressure and (3) the big red door that consists of a frame with a flexible panel                                     that fits into an exterior doorway of the home.
  

•                              By measuring the pressure and airflow inside and outside of the home in relation to each other, the air                                         tightness of the building envelope can be quantified.
