Cheyenne,
Mine is full 1" or 1 1/16th". My window trim and corner boards are 2 3/4" or 3" x 4". It was kind of like bolting a 4x4 at the windows and corners
. This did allow for hidding the stainless toe screwed fasteners. I was soo fearful of "bleeding" of ANYTHING steel, even though they were all hidden (even under the lap), that I insisted on stainless throughout. Haven't bled yet
. As for rot of sapwood, never seen it locally on ANY flitch siding even ones w/ "differed maintainence"
Certainly isn't occuring on mine.
