I've looked all through the discussion threads and can't find any mention of the use of the ZIP systems wall and roof panels. It's a coated OSB with a 1" or 1/2" insulation bonded to it. It's a structural panel that has the OSB on the outside and no housewrap is required. The window and door nailing flanges would be installed on the outside OSB surface, along with the siding (Smartside, Hardie, etc.). For maximum wall strength, one would want the panel to extend down to the bottom of the rim board and lap back up the wall. This would provide insulation and a water barrier all the way down to the top of the footing.
With Chief's Wall Type framing rules (Main and Exterior layer definitions), I'm not sure if this needs to be 2 wall types or if the ZIP panels would be placed as a skin around the house?
Anyone out there designed a house with this type of walls?
