IBC 1407.11.3.3.2 defines Class CC1 Metal Composite Materials as having a lower burn rate than class CC2.
Table 1407.11.3.4 allows class CC1 to have a greater % coverage and area than CC2 for fire separation distances of 6 to 30 ft., but lists the maximum area of a CC1 panel with over 30 ft. fire separation distance as “Not Permitted”. Should that say “Not limited”?
