An old NA woodframe building will have ¾” plaster on ½” plaster and horse hair mix on ½” wood lathing. The base for the lathing was often a full layer of 1x sheathing boards. Framing was typically a full 2” and a lot of it. Layers of sheathing, siding built up interior and exterior mouldings and trim work add up substantially. So overall wood layers could add up to 3-4”. Significant interior mass with the walls. Substantial overhangs, recessed (cutting wind surface) and smaller windows (generally utilizing storm windows). Generally good siting and landscaping.
