Energy-efficient walls with conventional building techniques
I’m building a house in Zone 4A. The builders here are all very conventional. They are comfortable with 2 x 6 construction [or 2 x 4].
Can a staggered 2 x 4 wall be built [to minimize thermo bridging] on a standard poured concrete foundation? Does staggering require significant additional materials and/or labor?
Would a 2 x 6 standard wall with a 1” exterior sheet insulation be better than a 2 x 4 staggered wall?
Given the constraints of traditional building techniques available, what is the best way to go?
