This siding job was a collaboration of the homeowner & I. With much research of products that could sustain Wisconsin's seasons, we came up with this. We used a Marine grade plywood and Galvalume metal between the plywood panels. It is fastened with a #10 1-1/2" stainless steel screws to give it an industrial feel. When you stand back they almost look like rivets. We were all pleased with the outcome.
