T1-11 comes in 4-foot heights. If your wall is taller than 8 feet, you’ll stack panels. Before installing the upper panel, apply over the horizontal joint. Lap the flashing behind the upper panel and over the lower one—like a shingle.
Tip: To cut T1-11 cleanly, score the grooved side with a utility knife, then cut from the smooth back with a circular saw.
House wrap (or tar paper) and Z-flashing for horizontal joints.
