Testing conducted at QAI Laboratories, IAS accredited fire testing laboratory and CALFIRE Approved Testing Laboratory
ASTM E 84 (NFPA 255, UL 723), 10 minutes:
Firefree Class A, Flame Spread Index 25, minimal thickness of 6 mils (.006 inch) dry application.
Firefree Class A, Flame Spread Index zero (0), minimal thickness of 10 mils (.010 inch) dry application, it also meets the requirement for smoke developed index of 30 (≤50) smoke characteristics used in air plenum spaces.
Firefree Class A tested on ¾” OSB & 2x6 Douglas T&G at 20 mils (.020 inch) dry thickness achieved a flame spread index of zero (0) and smoke developed index of zero (0).
Firefree Class A tested on 7/16” OSB at 20 mils (.020 inch) dry achieved a flame spread index of zero (0) and smoke developed index of ten (10), and show no evidence of significant progressive combustion when the test is continued for an additional 20-minute period.
Firefree Class A tested on ¾” OSB at 15 -20 mils (.015 inch) – (.020 inch) dry achieved a flame spread index of zero (0) and smoke developed index of 15.
Firefree Class A tested on 2x6 Douglas at 8 mils (.008 inch) dry achieved a flame spread index of zero (0) and smoke developed index of 45, it complies with Chapter 7A of the WUI fire zones.
In addition to the testing performed, although it is not required by the test standard, char damage measurements were taken to effectively show the high performance level of the coating. Based on the results obtained from the 30 minute extended test, the wood materials tested showed minimal char damage, showing FFA’s ability to assist in maintaining the structural integrity of the wood materials in a fire situation.
