How should siding be applied?
Horizontal siding is nailed directly to the panel wall passing through the air and moisture drainage systems. Keep nails at least 6″ from splines to avoid rippling of the siding. With shingles, you may nail into strapping without worry. With vertical board-and-batten siding, horizontal strapping is recommended. Use 6d galvanized or stainless steel nails for clapboards and 8d galvanized or stainless steel nails for board-and-batten.
