How to Install WRB Sheathing (ForceField)

Corbett Lunsford

Grace and Corbett show the latest development on their home build- the wall sheathing, which is also the air tightness layer and weather barrier. It's called ForceField, and here you'll see a demo of why it's such an important component in the system, and how to install it for a higher performance home.

Corbett Lunsford

I've been telling people that the 475 High Performance Building Supply membranes I build with are airtight but vapor open for years. Turns out, sometimes I'm an idiot. Here's the real deal. Featuring Delphine Farmer and Marina Vance of the HOMEChem Experiment.

Most Airtight Barn at an Off Grid Homestead Ever?

Corbett Lunsford

Corbett performs a blower door test on LG Squared Architecture's #OffGridHomestead. Will Chris's toolshed beat the record set by the #DryVault? Will Passive House standards be outperformed? Will Corbett remember to plug in all his hoses?

Tour the Off Grid Homestead with Chris Laumer-Giddens

Corbett Lunsford

Last week I made my first site visit to the mountains of North Carolina to start performance testing the #OffGridHomestead. This is an uber-homebuild with LG Squared Architects (now also LG Cubed Builders) and Chris Laumer-Giddens has a lot to show us, even at this rough in stage, with saws running and tractors rumbling around.

2 Years Later: is #TinyLab Still the Highest Performance Tiny House on Wheels?

Corbett Lunsford

Grace and Corbett built the world's highest performance tiny house on wheels in 2016. It was perfect. Then they toured it 13,000 miles across America and let 7,000 people come inside to feel, hear, and smell what perfectly tuned home performance is like.

What's the house performing like now, after all that torture? And under 2 inches of snow in Atlanta, Georgia? See for yourself in this 20-minute tour, complete with testing, demonstrations, and metrics that show Proof Is Possible, even for people who have never built a house before. The #TinyLab is still the undisputed most scientifically superior home performance demonstration in the world, and we sincerely hope others start challenging our work!
