Work on the “barndominium” project is nearly complete after 18 months of construction. You can read parts 1-5 here on GBA (linked at the bottom of this post) and on this blog, links to the right labeled Barndominium Project. This final post will discuss mechanical systems, blower door numbers, along with the challenges and benefits of this type of building method.

Those of you that have been following this blog for a while know I have been involved with a local project, I’m calling the Barndominium. It’s part conditioned storage and part home, nearly 10,000 square feet in total and a true post and frame structure with posts at 6-foot centers and no structural sheathing anywhere.

I was brought on the barndominium construction team after many decisions were already in place. The design was, for the most part, finished. Many of the assemblies had been designed, such as the decision to use laminated posts six foot on center with the horizontal wall girts both inside and out. The original plan for the insulation was to use up to seven inches of closed cell spray foam in the walls. I was able to change the insulation strategy with a plan for a more “forgiving” assembly. We chose to go with Rockwool’s 7.25-inch ComfortBatt, which has an insulation value of R-30. Continue reading “Barndominium Part 4-Insulation and Air Control”

When I first started planning the water and air control details for the barndominium project, I knew the windows were going to be one of the tougher parts. Window framing for a typical post and frame building consists of a simple 2x wood frame extending horizontally between two posts, which in the case of this structure are six feet on center, with two vertical boards fastened between the upper and lower horizontal frames. Once the basic frame is constructed inside the wall cavity, horizontal wall girts are placed over the framing, a kind of window buck, if you will. My original thought was to have the window buck placed around the window rough opening, flash the buck so I could extend the window flashing back to the Majvest WRB, then add the needed wall girts for fastening the cladding. In my mind, this wouldn’t be a difficult assembly to build, the framing crew didn’t agree. They insisted on not changing their usual assembly of having the exterior wall girts installed, then for me to have to figure out how to extend the window flashing to the WRB.

The bardominium, part storage facility, part shop, part man-cave with a home inside. Working on this type of project has had its difficulties. We have taken the framing crew outside their comfort zone, though they are well versed with post and frame structures, they were not familiar with many of the materials I was asking them to work with. I was able to have them change some of their sequencing, but I lost of few of the battles. On top of those difficulties, the project started about a month later than expected forcing crews working during sub-zero temps, that’s, 0°F. Progress at times has been slow. The foundation portion earlier in the fall went well, though I think I would change a couple of the decisions we made. More on that in a bit.

What is a Barndominium?
A building technique that uses the shell of a typically less expensive barn or post and frame structure to be used as a home. (Don’t confuse post and frame with timber frame.) This “house” often includes a large garage or shop space, or maybe a better description is the garage or shop area includes living quarters.
