Figures 2-13F and 2-13S illustrate a variant on 2-12.  It consists of a concrete masonry (CMU) foundation wall with exterior insulation. This differs from figures 2-12 in that above grade wood frame wall is constructed of 2x6 framing which overhangs the foundation wall. The overhang can be up to 2 inches while maintaining 3 ½"; of bearing over the rim. Consult with a structural engineer to make sure the bearing over the rim is still adequate for your project.
