I worked with Thermax CI for the DOMUS project which is the same as Thermax HD except the external facer is blue instead of white.
REF: http://domus.urbanaction.org Thermax CI and HD is designed to be exposed outdoors for 6-12 months and has a great thermal rating and reasonable fire rating. The increased price difference is because its DOW :( At the time i was interested in using Hunter XCI but they didn't wish to communicate. Thermax is expensive and difficult to source on the West Coast but I used http://foamsalesandmarketing.com/ in Burbank, C.A. for supply.
