Is StormBlocker® fire proof?
StormBlocker® is not fire proof, however it is classified as an ASTM E 84 Class A material by the Hardwood Plywood and Veneer Association Laboratory and Testing Service. The Class A rating means it takes significantly longer to ignite, burns much slower and has less smoke than wood. The average burn rate per foot is over 39 minutes making StormBlocker® more like a concrete product than wood.
