Can this foam be left exposed in an attic or crawl which has a heat-producing appliance, such as a gas pack or gas-fired hot water heater?
YES, Icynene’s report, number ESR-1826 details that the foam may be exposed in attics and crawls without an ignition barrier or thermal barrier. This is not true of all foams. See section 4.4 of the ICC reports for each foam to find out of they may be sprayed without extra precautions, or if they may be exposed in the presence of heat producing devices. ALL foams have additional conditions for being left exposed, again check section 4.4 for a list of those conditions.
