I have a project where there will be a reverse board and batten siding detail. We bypassed blocking between studs on the interior, for nailers, so that it will be easier for the dense pack cellulose to be blown in. I am planning on putting 1.5″ x 2.75″ horizontal nailers 24″ OC on the exterior over the Zip sheathing to serve as a nailing base to the vertical siding. I know this has been brought up before, but just want to double check. Would it be beneficial to kerf the horizontal nailers where they meet the sheathing for water drainage? Or will the airspace alone with the sun hitting be adequate for drying.
I am located in the humid southeast NC. Zone 4b. Thanks.
