The Future of House Wrap: a Stronger, Insulated, and More Airtight Envelope

At the Tallwood Design Institute at Oregon State University, we found a mockup built by our friend Mark Fretz, whom you'll be hearing more from. This is an experimental use of Mass Plywood Panels (MPP) and wood-fiber insulation for multifamily buildings and other homes.

One note: they don't seem to have termites up there, so this would be extra experimental around Atlanta, where we certainly do have burrowing insects of all kinds. Season 3 of 'Home Diagnosis' coming soon: https://HomeDiagnosis.tv

Building an Affordable Airtight Home: Sheathing Sealed (Will It Work?)

We got called in to test this before/after on one of Matt Hoots’ projects at Sawhorse in Atlanta (https://sawhorse.net/). It was an interesting blower door test series with some surprising results. Also featuring Tommy Sharp, co-inventor of ThermaCote (https://thermacote.com/).

Radiant Barrier: How Does It Work?

'Home Diagnosis' co-host Corbett Lunsford uses an infrared thermal camera to demonstrate how a radiant barrier works. This one is built into the Thermostat roof sheathing, and it needs to be kept clean and have an air gap against the radiant barrier coating.

Advice on Foundation Insulation Cladding?

After carefully exploring the options online, I believe no one in the high performance building world has published a truly durable and beautiful solution for cladding exterior insulation on a foundation wall. Here's my particular conundrum, and my concept for a product that would solve the issue. Any heroes out there who can point me in the right direction?

100-Year Roof: Mento 3000

See 475's high performance Pro Clima roof membrane get installed on this 3:12 pitched roof, before the rain screen , exterior insulation, and eaves get put on. More on this project at: https://HomeDiagnosis.tv/atlanta-homestead

How to Install WRB Sheathing (ForceField)

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.

Building to Control Humidity

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.
