First of all, if you don’t want to read about advanced wall systems and their benefits, watch the video!
Second, here is a written overview of what we discussed in the video.
Current code minimum in Oregon is 2x6 wall framing with R-21 insulation
Zero energy homes require higher R-value walls that are well air sealed
Some states are starting to require 1” R-5 exterior insulation known as a thermal break shear wall
There are cost effective sheathing materials that integrate insulation and the weather resistive barrier (WRB) into one product that require less labor to install
Advanced wall systems include exterior insulation, double stud walls and ICF (insulating concrete forms).
Advanced framing includes 2 stud corners, stacked framing at 24” o.c., insulated headers, ladder blocking, raised heel trusses, and plumbing and electrical runs in interior walls.
