In the past, one EIFS product, trade name Dryvit as John mentioned, was tested and listed as an assembly through 1998. This assembly used a limited combustible foam plastic (Flame spread <25). However, because of the cost, the foam component was changed by the manufacturer to a cheaper foam insulating material that was combustible. The assembly could then not maintain its limited combustible listing.

If this documentation >is provided, it can be treated as noncombustible. If the documentation indicates all components of the assembly, or the entire assembly has been tested and each has a flame spread rating of 25 or less, it is treated as limited combustible. Dryvit assemblies installed prior to 1999, with proper documentation provided, are treated as limited combustible. Hope this info is helpful Salvatore J. Izzo III, P.E.

DryVit ( http://www.dryvit.com/home/default.asp) is one if not the largest manufacturer of EFIS, also referred to as "Outsulation". Bottom line the manufacturer will need to provide the test data.

Obviously this stuff can be very nasty. Is it safe to say that ALL EIFS systems are combustible, or do I have to look at them on an individual basis?

Whether it's limited-combustible (or not) can have big impact while wading through sections 8.15.1 and 8.15.7. I've been searching on-line and haven't found a definitive answer. I've seen the stuff used as the ceiling on exterior canopies (such as a bank drive-through) and exterior entryways.
