15,000 lbs of Rockwool Insulation: Crossfit Challenge

Corbett Lunsford

Maybe you've seen people wrestle with tires or climb ropes or do push-ups. They are all ninnies. This is how you work out for real- by hugging Rockwool (aka Roxul) and strutting around your acreage. Stay tuned to see all these rocks get installed in a perfectly performing house.

Retrofitting for Performance: Crawlspace Encapsulation

Corbett Lunsford

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.

5 Kinds of Ventilation for HOMEChem Control

Corbett Lunsford

Ventilation is simple in concept- it moves bad air out and good air in. But the applications can be intensely confusing- Grace and Corbett help peel the onion of controlling home performance dynamics (and the HOMEChem issues we're learning more and more about) using fans and controls available around the world.

Featured systems are AirCycler, Fantech, Broan-Nutone, RenewAire and Ultra-Aire.

Tiny House Plumbing Puzzle Took 2 Years to Solve

Grace McPhillips

The #TinyLab's plumbing system is highly efficient for water, electricity, and propane use, but it turns out that efficiency reduces the control over water temperature during different seasons. Corbett FINALLY solved the conundrum theoretically- but are the products available in the plumbing department going to perform as advertised?

HOW TO BUILD A SHOJI DOOR FROM PUREBOND PLYWOOD

Corbett Lunsford

Our #TinyLab is a touring tiny house on wheels, which means it takes a lot of abuse as we travel the U.S. on the Proof Is Possible Tour. We’re teaching home performance, showing people how to get diagnostic proof when doing home improvements or building/buying a home.

One of the major problems in the home market is that people just don’t know what they don’t know. They don’t know that air leakage is the biggest problem in their homes, they don’t know that they’re making carbon monoxide every time they use a gas stove, and they don’t know that the formaldehyde in plywood is slowly poisoning their families. That’s what the tour is about.

Because we built the #TinyLab very airtight, almost every visible surface in our home is made of Purebond Formaldehyde-Free Plywood. We didn’t even waste time thinking about air purifiers or other band-aids; if we don’t want toxins in the house, it’s easier if we don’t bring them inside in the first place. We decided to use the Purebond for our Shoji Door to the bathroom, too- faster than using wood framing pieces, and going with a hardware-free sliding door would mean more durability overall. Here’s how the door was built:

1. Cut two sheets of Purebond ½” pre-finished plywood to size, with an extra ½” in each direction. Clamp them face-to-face. Measure and trace the cut-outs on the unfinished top side, putting the extra ½” along just two edges (i.e., bottom and right side) so that the other two edges are your reference 'finished' edges. You'll cut the extra ½” off after the door is assembled, to ensure a flat, straight edge on every side.

2. Cut the two sheets with a jigsaw to create the spaces for the rice paper, and any vents for pressure relief between rooms.

3. Dust the sheets off and stain the interior cuts you just made to match the veneer.

4. Prep your glue table with clamps- lots of them. Cut your rice paper to fit the full span of cut-outs with 1" to spare on each side.  Working fast but thoroughly, spread glue on the unfinished faces of both sheets simultaneously, and sandwich the rice paper between them.

5. Clamp the hell out of the assembled door, making sure the rice paper is taut, the cut-outs line up, and the two finished edges are even.

6. After letting the glue dry, unclamp the double-thickness door and cut the extra ½” away from the two edges, leaving all four edges perfectly even and smooth. Stain the outside edges to match the veneer.

7. Install the Shoji door in the jamb where it will slide (we used a pre-made sliding door frame, and removed the hardware and metal components for wheels) and seat it in a 1/16" waxed groove in the threshold. Attach adhesive felt strips to the pocket jamb to keep the veneer from being scratched.

8. Install the door and the jamb pieces that will lock in the top and closing side- DONE!

How to Insulate a #TinyLab (and any other house)

Infrared expert Corbett Lunsford uses the FLIR T660 infrared thermal camera to illustrate how insulation was installed in the #TinyLab for optimal control over heat bleed.  For more info about where you can tour the #TinyLab on its 20-city Proof Is Possible Tour, visit:

How the Tiny Lab Tour Idea was Born

Corbett Lunsford

Welcome to our mind palace!  Typically Grace has her eyes closed and tipped back deep in magical dreaming and Corbett is intensely trying to figure something out with strong gestures. (as you can see in the thumbnail image.)

We wanted to let you in on how this idea came to be!  Our RocketHub campaign ends on Nov. 30th, and while we actually over sold the cities and blew past our original goal we have so many aspects of this tour that could use your support and funding.  Check out the details HERE- www.ProofisPossible.com please share and make a tax deductible contribution today.  THANKS!

How to Renovate a Home in Dallas- the RIGHT Way

Corbett Lunsford

Dear Corbett-
I am not a contractor, but a residential homeowner that has become increasingly interested in owning (and taking a part in creating) a high performance building. After going through several series of podcasts, I ran across yours, and immediately loved it because you went into greater detail about the things that I want to learn about; so I want to thank you for the podcast.
Onto my situation.... I am looking to buy an older (1940's) home that has no hvac, next to no insulation, and needs a good deal of work; but I believe it has the best potential for making a high performance home.... a blank canvas.
What I am having trouble with is finding the local rock stars that can really help me make my house as efficient and comfortable as possible with my given budget. Do you know of any really good people in the Dallas area that could get me on the right track? Thanks again for putting out all the info!
~Derek R.


Thanks for reaching out, Derek! I'm always happy to help, and I think the home you're considering is a GREAT OPPORTUNITY. A blank canvas is much easier to paint on, and when a house is fully 'finished' and has been renovated, it just means you'll have to dig harder and deeper to find and fix the issues that are lurking under the surface.
I'll hook you up privately with a few of my own black belts who are part of Fall Fast Track, but I also want you to know that when we take this show on the road next year for the Proof Is Possible Tour, we'll be creating a directory of pros who pledge to deliver guaranteed results across the U.S.!  Stay tuned here for further developments on that front, and keep in touch about your high performance home renovation!
Looking Forward,
Corbett
