This is essentially the final part of my series of posts detailing the framing of the exterior wall trusses - there may be a few revisits of specific things in the future. Part 4 is a short post on how I framed the corners (which I almost forgot to mention) and how I air-sealed the corners of the rim board (which I did forget to mention in
part 2).

| Choosing a picture to go "above the fold" is sometimes tricky. I chose this one because it shows a missing corner but also because I found the snow a refreshing reminder of a time when it wasn't so hot... |
Air sealing the corners of the rim board required a little trick. As noted previously, the 3M 8067 tape I have been using sticks well to the "smooth" side of the rim board but not so well to the "rough" side or the "end grain". The trick then when taping the corners is to use a piece of tape that is wide enough to span the "end grain" and stick to the "smooth" material on each side.

| In this photo I pulled the tape back from the "end grain" to see how well it stuck there. It was very easy to pull away and afterwards I was able to see that the adhesive was covered with what looked like sawdust. It is also possible to pull the tape back from the "smooth" portion of the rim board, but it is much more difficult and results in damage (stretching) to the tape. |

| Using 4" tape, I was easily able to span the "end grain". This is how the corners turn out after taping. Note the cardboard on the right that was put in place to prevent damage to the tape from long-term UV exposure. |
The corners were built simply enough after the rest of the "secondary" framing was done and top plates were installed all the way around. The corner pieces consist simply of a single 2x4 with a 2x2 nailed to it then toe nailed at the top and bottom plates.

| A "corner stud" at the bottom plate. Since this stud is only nailed in at the top and bottom plates (ie: there are no gussets that tie it to the "primary" structure) the 2x4s and 2x2 used were selected for their straightness. |
