While we're on the topic of EIFS, and not specifically a fire problem interesting reading ion another stucco like finish;
Stick-on stone worse than EIFS? By Clayton DeKorne /JLC Sept 25, 2013 Think of a stone veneer as stucco with chunks of concrete embedded in it. Those chunks of concrete absorb and hold a lot of water, so you have to have a system that can drain. Otherwise, all that water held in the cladding will eventually find a way inside. Adhered concrete masonry veneer (ACMV) has been increasing in popularity as a cladding on mid-range and high-end homes for the last decade. According to building consultant, Mark Parlee, a huge number of these homes are now showing signs of water-damage. Parlee believes the problems with ACMV have the potential to dwarf the EIFS failures common in the 1980's and 90's. That's because ACMV is more like stucco with big chunks of concrete in it. Those chunks tend to absorb and hold a lot of water, which will find its way inside if the cladding assembly is not detailed correctly. The primary requirement is to make the assembly drainable, using a well-detailed weather barrier covered by a rainscreen mat. According to Parlee, most most contractors installing stone veneer treat it as if the stone will shed water instead of absorbing and holding water. ACMV, he argues, is a lot like brick veneer, only we aren't in the habit of installing it with an airspace behind it the way code requires for brick veneer. Look for details on how to create a drainable cladding assembly with ACMV in the upcoming October issue of JLC. Parlee's system builds on the Masonry Veneer Manufacturer's Association Installation Guide [PDF], and relies on a rainscreen mat, such as one shown in the "Rainscreen Sources" sidebar on this page. http://www.masonryveneer.org/pdf/MVMA%20Installation%20Guide_3rd%20Edition_F inal.pdf John Drucker, CET Fire Protection Subcode Official Fire / Building / Electrical Inspector New Jersey -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of John Drucker - Home Sent: Friday, October 4, 2013 8:59 PM To: [email protected] Subject: RE: EIFS Borgata Fire - Atlantic City NJ http://www.fireengineering.com/articles/2010/05/modern-building-materials-ar e-factors-in-atlantic-city-fires.html Alucobond - Polyethylene Core (Available in FR Core) http://www.dryvit.com/fileshare/doc/us/specification/ds118.pdf Dryvit - Expanded Polystyrene.

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. Regards Jim DAVIDSON ASSOCIATES Fire Protection Engineering P. O.

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.
