The second weekend of building with Stefan was really good. We had hoped that my ridge been would be here so that we could start working on the rafters, but the sawmill was unable to deliver my 22′ 4×6 ridge beam. Plans were changed – instead of rafters, we set out to finish the 4th wall of the house and the 4 walls ready for siding. I ordered 4’x8′ sheets of 1″ extruded polystyrene insulation to put around the house to help increase the Rvalue of my walls. Code in Québec calls for R25 in walls – in order to get that kind of Rvalue in my walls and keep as much interior space as possible, the exterior walls have to be insulated as well.
Before we insulated, we finished the 4th wall of the house which was different from the first three for several reasons. I have chosen to almost create a bay window in that end wall of the house. Doing so creates some interesting challenges in a tiny home. The plans for the house call for parallam posts and beams in that wall along with a threaded rod under the window and strapping around the edges. I could not find the exact posts and beams required and ended up with slightly smaller posts (1/4″ smaller on one side) and beams that were almost 2″ wider. Parallam is an engineered wood, quite beautiful to look at. It is also heavy. The wall went together pretty quickly and then we built the loft framing.
By the end of Saturday, we had the 4 walls built and sheathed. Sunday we only did a half day, we put up the insulation, wrapped the house with house wrap and then put up strapping until the nail gun ran out of nails. Not bad for a day and a half.
