What’s A Blower Door Test?

Make It Right builds homes that are highly energy effective, which includes allowing minimal air leakage along the envelopes in our homes. An airtight home stays cooler in the summer and warmer in the winter, making it less expensive to heat and cool.

A blower door test locates air leakage sites along a home’s envelope and tests duct work for leakages as well. Per Wikipedia:

Blower door tests are used by building researchers, weatherization crews, home performance contractors, and others in efforts to assess the construction quality of the building envelope, locate air leakage pathways, assess how much ventilation is supplied by the air leakage, assess the energy losses resulting from that air leakage, determine if the building too tight or too lose, determine if the building needs mechanical ventilation and to assess compliance with building performance standards.
