   I sandwiched 1" x 4' x 8' solid foam insulation between a 1/2" sheet of plywood and 5/8" sheet of T-111 on the outside.  For the sides I ripped some 1' strips, of course you will need to slice 1 1/2" off the insulation.  This worked quite well but your dimensions are a lot bigger than mine. 

   My RO was almost exactly 4' x 8'.  You could adapt my design for the size you are dealing wiht as the stiffness of the doors comes from the skins not so much as the insulation.  Getting the 9' height would be the biggest challenge but not a show stopper by any means.

   My door is a traditional sliding barn door as well.  To seal around the edges, I used weatherstripping.  The catch is designed so that when the door is closed, it pulls the door in to engage the weatherstripping so as to keep the wind out.  Seems to work quite well.

   Also, you will need to reinforce areas for the the hangers on top and wherever you want to mount a door handle.  For this I cutout blocks and inserted 1" boards that were captured by the mounting screws for the door hardware.  Do this before placing the last skin!  Yes I did make that mistake, but recovered B4 it turned into a mess!

   Thanks. Sounds like a great solution. With a little figuring I think I may be able to adapt your design.
