Cladding a passive house, how are you handling the deep insulation?

Cladding a passive house is its own headache because you've got a thick layer of exterior insulation, so the cladding ends up sitting well off the structural wall and you have to figure out how to hold it out there without bridging all that insulation. Rail systems bridge the least but cost more, long screws and wood furring are cheaper but bridge more. For the wood itself, pick something stable and durable since you won't be getting back there to maintain it. I went with stable thermally modified ash from a specialty hardwood supplier and matched the profile to the rail spacing. Plan the cladding and the attachment together.
