Where are you? I saw recently at a timber &log show that there is a SIP available that is flame retardant or flame extinguishing. The foam itself is flame retardant. I'll have to look at home for the info. I've heard that traditional sips will burn. Apparently these newer sips have been on the market for about 6 years or so. I was also told that a 4 inch sips of the retardant material will replace a traditonal 6 incher and have the same R value for example.
