Firefree Class A passes the ASTM E-84 30 minutes test at a low thin film thickness.

Firefree Class A, applied at 8 mils dry thickness, registered a zero (0) flame spread index and 45 smoke density index, also qualifying the coating for air plenum spaces (as required by mechanical building codes). At this low thickness of one coat, the coating will comply with the same acceptance criteria used for fire retardant treated wood (while other coatings would require multiple coats).
In addition, the coating complies with the California Building Code requirements Chapter 7A-5, for eaves/soffits with the Wild Fire Zones, Wildland Urban Interface (WUI), which most insurance companies require to reinstate coverage.
