The standard fastening and overlap patterns should be used when installing siding to ensure optimum performance.  Hemmed corner flashings should be used for strong neat corners.  Other flashings you will use when installing side panels are drip cap (over windows), J-Trim (around windows and doors), and door jamb flashing.  You should not run siding panels all the way to the ground, and the bottom edge should be terminated on a base flashing.  When the wall consists of more than one panel in each vertical row, install panels from the bottom up so water is directed away from, and not into, the lap joints.  Siding panels installed horizontally should have Butyl tape or caulking applied at the vertical laps, as this will ensure weather-tite joints.
