For the new shed we are considering installing thin faux stone but in a wainscot style to the bottom of the largest window (about 30" above the foundation) with ledge stone at the top (rest of wall would be vinyl siding).

On another wall I have two lower windows that are about 16" off the foundation.

All the windows have the integral "J" channel to accept the vinyl siding.

What I haven't been able to find in any of the installation document is if the ledge material would just stop at the side of the low window or if it would wrap down and across the bottom.
