I agree with Todd that you would be better off if someone else made the call. Or are you bidding a design/build project? Perhaps share the load by hiring an engr as a sub to you. Other thoughts: How about the owner's certificate -- now required by 13? Can you get a commitment on product and quantity from Ace? If you are going to try and figure this out on your own, look at the volume of polystyrene foam as a percentage of product volume. IFC has both weight and volume percent limitations to call it Class IV. There is also a limit on how much Group A you can have without classifying the whole place as Group A.

In a perfect world, they should have a PE or at least the insurance carrier making that determination. Does ACE have a standard specification?
