From Madeline Smith, HOLT cost estimator extraordinaire:
Both systems have metal studs or CFMF, so on top of that, typically we would have sheathing, a weather barrier, and to compare equals, 3" of polyiso rigid insulation. This wall assembly costs around $6/SF (plus the CFMF).
vs.
The metal panel Mike, Centria Rep, introduced as a substitute is $11/SF (http://www.centria.com/wallpanels/Pages/InsulatedCompositeBackup.aspx).
