Watch as Corbett and Grace test their airsealing work on the Tiny Lab with a Retrotec blower door! They fire up the new Model 5000 fan and find that the house has approximately 160 CFM@50 of air leakage, which is 4.7 ACH50 and 0.14 CFM per sq. ft. of enclosure surface area- and that's with stupid tarps over the window holes! We're going to test again when the windows are in.
Thanks to Julie Tolliver of Energy Fitness for Homes for the idea, to Retrotec for making awesome equipment, to 475 High Performance Building Supply for supplying America with awesome airsealing kits, and to Hewlett-Packard for creating awesome video editing stations that we work on every day.
