Corbett digs into the weather barriers, structures, airsealing and insulation layers of the high performance house in Atlanta, which will be featured in season 2 of the Home Diagnosis TV series.
*CORRECTION: Pango Wrap is 15-mil thick, not 20, but is still a 0.01-perm vapor barrier.

Welcome to the #DryVault, a super airtight, insulated, and dehumidified tool shed for the Building Performance Workshop's diagnostic tools in Atlanta, GA. Corbett will be helping homeowners make higher performance decisions on home improvement and new construction in Atlanta from this home base, and we can't wait to show off the framing and airsealing systems used here! For more on the airsealing products used, check out 475 High Performance Building Supply.
Grace and Corbett Lunsford walk through the process of engineering their Tiny Lab, a tiny house taking them on the Proof Is Possible US Tour! Tonight's episode is on designing the barriers to heat bleed, air leakage, and water leakage.
WORKING TINY LAB SPECS: Floor 2x6 with R-21 EcoBatt insulation. Walls 2x4 with R-15 EcoBatt insulation. Ceiling 2x6 with R-21 EcoBatt insulation. Air leakage down to 2 ACH50 or less.
I struggle with frustration, and you might be able to hear it in this presentation. I'm frustrated that as a relative newbie in the homebuilding industry, I'm constantly seeing work done thoughtlessly, or at least with not as much thought as work deserves. Sorry if I come across as an a-hole, I promise I'm not- I just care a whole heck of a lot, and I spend all day in buildings where my caring comes back to haunt me.
