1 1/2" extruded foam on outside between wall girts (Tyvek outside of building).....2" spray foam on inside.....then fill out cavity with 4' wide R11 fiberglass. (bat has vapor barrier but it's turned toward spray foam so as not to create a double barrier that could trap moisture) Will then line with plywood up 8 ft and steel above that.
