Anyone have any experience or thoughts/analysis on the Nudura Ceiling Technology system?

I'm having a hard time finding reviews.  I would be curious if any building science guys have looked at the system.   Also, anyone installed it and have thoughts?

It seems like a pretty good concept.  Most insulation is from the drywall attached to the roof truss up, where this is going the other way.  As long as you can account for the loss of ceiling height, should not be an issue.

Thoughts?
