I heard yesterday about a new spray foam product that had a flame spread rating that met code without the application of an additional coating – Apparently it is a distinctive color so building inspectors can recognize and sign-off on it.

Does any one have any info on who is producing this product and how the pricing compares to foam with flame spread resistant paint applied after installation of the foam? Does it contain halogenated flame retardants? Is information available on what the flame retardant used is (TPP? or TCPP?)
