I am almost to the siding portion of my extension project. I am thinking of using James Hardie fiber cement vertical panels unless I come across a product that might be easier to cut. I don't want to use T 1-11. For the drain plain, I was thinking of installing 3/8" plywood furring strips OC studs vertically (OSB and house wrap already in place) to assist with moisture drainage. Watching many videos and reading info online, I see many installations where the panel is secured directly over the house wrap with no gap (no furring). I live in coastal Virginia and consider it to be an average rain fall area. Does anyone have any pros and or cons for using furring strips? Also, any experience with using a different vertical panel other then Hardie board that I should consider? Thanks..
