Matt Risinger sits down with special guest Randy Williams, Editor of Green Building Advisor, to discuss blower door testing and its role in building high-performance homes. Drawing on his experience as a builder, energy auditor, and building science consultant, Williams explains how blower doors measure air tightness, identify leaks, and help verify the continuity of a home's air barrier. They cover common testing mistakes, the value of pre-drywall testing, and ways to locate air leaks using thermal imaging and smoke. The conversation also examines air sealing between garages and living spaces, code requirements, and the challenges of achieving tighter building envelopes.
