The inherent fire resistance of a Sika Sarnafil membrane is evidenced by successful achievement and full compliance with roofing's most significant fire safety requirements. Sarnafil membranes enjoy certification under the strict fire code standards of more than twenty countries throughout the world.
PVC roofing membranes such as Sika Sarnafil can self-extinguish and resist the spread of flame. In a laboratory experiment, a flame source was applied for ten seconds to SBS modified bitumen, fire retardant TPO, Sarnafil membrane, and fire retardant EPDM. When the flame source was removed, the Sarnafil membrane extinguished the fire, while the alternative membranes continued to support combustion.
