We haven’t posted about the inside of the house in a while, but that doesn’t mean we’ve given up. Slow progress is still being made on the future master bedroom. After the window was installed, I started on some structural details. This picture provides an overview:
The green boxes highlight straps. These are six 16 gauge metal straps that I added to connect the base of this wall to the top of the first floor. In the event of an earthquake, this will help hold the two levels of the house together. I added some doubled studs in the wall to provide more nailing surfaces around these straps, and added blocking at the middle point of the wall (highlighted in red). At the base of the wall, highlighted with a blue box, you can see insulation and more blocking. Our house has decidedly non-standard construction around this area (called the band joist), so this arrangement of insulation and blocking is probably unique to our scenario. With the straps in place, I caulked holes and then proceeded to add fiberglass insulation:
As I’ve mentioned before, our primary construction goal is a “super insulated house”. I still haven’t written up an explanation of the complete design, but suffice it say this fiberglass is the first of three layers of insulation that will comprise the final wall. With the fiberglass up, I then nailed up OSB panels:
The OSB adds shear strength to resist lateral forces from wind and earthquakes. The panels were staggered down the wall, and all edges were nailed off into blocking using 2.5″ ring shank nails. At the corners, nails connect these OSB sheets into the same studs that support the knee wall bracing.
