EIFS curtain wall systems have various type of backing material which range
from heavy gauge galvanized steel sheeting, to un-treated 1/2 inch plywood.
When installed on a building façade the voids between the curtain wall and the
building structure can become combustible concealed spaces. And when certain
dimensions are exceeded are required to be sprinklered. You have to be careful
when the EIFS panels are installed on clips which suspend the curtain wall away
from the floor slabs. John Drucker probably has some very good examples of the
problem.

Thanks for graphic video lessons. 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?

Is EIFS considered a 'limited-combustible material' per NFPA 13?
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.
