A blower door test calculates the volume of air leakage within a building. The use of a blower door along with thermography can be very beneficial for the builder and most importantly for their clients.  

This is also used to locate wind-driven water leakage. A blower door and Thermal imaging are crucial in the new home construction or renovations before drywall is installed after the installation of the vapour barrier or spray foam application to identify areas of any air infiltration from the application process. Air infiltration can do more than having higher energy bills and discomfort, It can also cause possible mold growth and deterioration of building materials. Water exists in the air as a solid, liquid and gas.
