Exterior OSB thickness

728 Views 6 Replies 5 Participants Last post by  Gary in WA
My local code list 3/8 or 1/2 inch OSB on 16" OC studs for exterior walls. I am ready to hang 7/16" OSB thinking it falls in-between the sizes listed somewhat. Before I put nail to OSB, would 7/16" work? I am in Virginia, my county goes by state code. Thanks for any advice.

Just be sure to leave the required gap between them, says right on each sheet. They may bubble off the wall, siding and all, later- otherwise. Also, run them vertically so you won't need the required shear blocking at all edges (exposed/no framing) for your wind area; corners and every 25' shear panels, check your special nailing spacing here also;
