My sheathing stops above sill plate and part of the plywood decking (See photos). I am installing hardiplank and don�t know how to handle first row. (1) Should I add additional sheathing strip to cover area to extend to the bottom of sill plate or is there a way of installing first row and have thinner starter strip start at sheathing without doing this? (2) If additional strip is needed to cover sill plate, could this be a cedar strip instead of plywood as I have lots of cedar from old siding I can cut down? (3) If cedar strip is acceptable, can I make this strip �" in thickness which would be wider than the �" sheathing above. This could also act is the starting strip. (4) How about the tyvek � could it go over the bumped out thicker strip (normally starter strip is nailed on top of tyvek)? (5) How far should hardiplank hang down below sill plate?
