Building to Control Humidity

Corbett Lunsford

It's easy to overthink building science decisions- here, Corbett quickly summarizes the basics of controlling moisture in the Lunsford family home build, and for any home. Interactions between materials and systems like GP ForceField, Rockwool Insulation, and Ultra-Aire ventilating dehumidifiers are simple to understand if you use the 4-3-2-1 approach.

Geotechnical Engineering for Foundation Footings: Dirt Performance and 4-in-1 Form-A-Drain

Corbett Lunsford

Corbett hired Geoff Hebner of Padstone Geotechnical Engineering to ensure the house being built will stand for a hundred years or more.

In part 2, Corbett shows the grading and leveling process with 6-8" lifts and 4x compaction using a remote-controlled trench roller.

In Part 3, Geoff returns to run a simple geotechnical test on the compacted dirt before pouring concrete, and Corbett finds out he's not as slick as he hopes.

FINALLY, we get to pour the concrete once the footings are finished with rebar, and well-supported per Geoff’s geotech engineering specs.

Using 475 High Performance Building Supply materials, Corbett and his dad are encapsulating the vented crawlspace of a one-story ranch home in Atlanta. See what a difference the improvements make to the test data from the Ultra-Aire Sentry system and the blower door.

Tuning the Enclosure of our Atlanta Home Build

Corbett Lunsford

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.
