Double stud-wall construction: inner or outer load-bearing wall?
I have been investigating a lot of framing options to achieve a relatively inexpensive, high r-value wall and have decided on building a double stud-wall made of 2-2x4 walls with a 7.25" space in between (to achieve what I want for an r-value). I have come across differing methods of distributing the load from above; inner versus outer load bearing wall, or a combination of the two (inner for the second floor joists and outer for the roof trusses). And then there is Larsen Truss construction. This also dictates the foundation below and the complexities that can exist regarding thermal breaks from the concrete. Right now I'm thinking of an inner load-bearing wall but a foundation wall for each wall (with 6" EPS foam in between them for a superior thermal break). Thoughts on load-bearing options?
