That must be regional. I live in the PNW, and it's pretty temperate here (the last few days notwithstanding...). House construction is still 100% 2x6 for exterior (and interior load-supporting) walls. Most houses are not being built with foam on the outside. I've heard of that happening where it's legitimately cold, though.

I've seen variations of this in El Paso (only 1 in foam) for high end housing where the cooling advantages can be sold. I doubt interior load supporting walls are 2x6. Often there are internal 2x6 walls, but that is to allow extra space for plumbing - 2x4 is plenty strong enough for load bearing in most houses, but toilet drains/vents don't really fit.
- rootusrootus 5y ago> I doubt interior load supporting walls are 2x6 Could be another regional difference. Our code requires 2x6 minimum for load bearing walls.
