Tim,
I don't know all that much about fire retardants and expanded plastics. However if you're looking at Rack storage to 25' high, you'll need to look at chapter 17, rather than 15.

NFPA 13, Table 15.4.1, Exposed expanded plastics, allows the use of ESFR, K
25.2, Pendent at 60 PSI in a building with Max Ceiling height of 40'.

Question: What level of fire retardant would be required on this product to
reduce Sprinkler System requirements? I have MSDS and manufactures
literature (which discuss fire retardant in product) if needed.

             Would any fire retardant built into the product help?

Thank you in advance.
