Not Lantana, but we went with vertical cellular blinds at Lowes that pull straight across entire 12 feet of doors. Another set for the 6 foot doors. Easy, smooth open and close and energy efficient. Wanted to take full advantage of the outdoor light and view.
Our double doors open from the middle and if ever do it again might consider left and right sides that meet in the middle. Wouldn't be as clean looking when closed though.

Lowes was easy to deal with and the installer very professional. They always seem to be "on sale."
