The tongue-and-groove profile along the edges and the biscuits at the butt joints kept the panel edges flat.
Since the panel ends were biscuited together, the panels didn't have to be trimmed to fit the stud layout.
An intentional 3/4-inch gap was left between the insulation-sheathing assembly and the foundation insulation and later filled with spray foam.
Sections of 3 1/4-inch by 3 1/4-inch by 1/4-inch steel angle were bolted to the wall underneath the door openings.
Spray-foam was used to seal the plates and boost R-values at the truss heels, and any open stud bays were filled with damp-spray cellulose.
