Since timber frames are load bearing structures in themselves, there are many options for insulation beyond 2x walls with fiberglass or foam between the studs. Ideally you utilize a system that doesn’t involve the redundancy of another load bearing wall attached to the timber frame. We often install panels on timber frames we build, but wanted to explore other methods in our own house. Our plan was to build double stud walls and then blow in cellulose for insulation. This would allow us to use a recycled product to create a wall with a high r-value. Building our own insulation system would also mean using our labor, rather than paying the panel company to pre-build and cut the panels. In the end however, it seemed like we might never have walls if we didn’t go the panel route—so that is what we did and thirteen days after the panels arrived we had a weather tight structure. It is still a thrill for me to pull in the driveway and see a building with windows, but I imagine it is only a matter of time before the beauty of black felt paper and orange cap nails wears thin and I yearn for siding and a porch.
