A Cold Climate Construction and Energy Blog
If you’ve been reading my blog for a while, you know I’m a big fan of Siga’s water and air sealing products, especially their tapes. Recently they came out with two products that substantially reduce the time it takes to flash window rough openings.

Cavity Insulation
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.

Guess what? I just won the lottery! (Not really, but for the purpose of this blog, let’s pretend.) I’m looking to build myself a new home. I have choices. I could build a McMansion with plenty of space I don’t need and will never use. I could concentrate only on the interior finishes and how the house looks. If you’ve ever read my blog, you already know what direction I’ll take. The house won’t be big, a couple thousand square feet is plenty for me, maybe a rambler with a second story over part of it built on a slab, no basement or crawlspace. Being a BS* guy, I would make an invest in the stuff that is hidden, those pesky control layers I often talk about. It would be based on the Pretty Good House concept.
