How PVC (Vinyl) Roofs Resist Fire
PVC roofing membranes are inherently fire resistant. Thermoplastic PVC is a naturally fire-resistant polymer, making this cool roofing material slow to catch or spread fire – and self-extinguishing when the source of heat or flame is removed. PVC roofs have passed both FM and UL fire testing. To see for yourself, view a dramatic fire test conducted by Southwest Research Institute’s Fire Technology Department.
The test compares the behavior of three common commercial single-ply roofing materials – vinyl or PVC, TPO and EPDM – after they are ignited by a Bunsen burner flame.
In the test, the PVC roofing sample self-extinguishes in seconds (13 in one, 12 in the other) after the flame source is removed, while the other two samples continue to burn for between 3 and 6 minutes apiece before they are completely consumed. Read the full fire-resistant roofing report.
PVC roofs have passed applicable FM and UL tests for Class A and B roof assemblies for high and low slope roof applications. UL and FM ratings are specific to individual roofing membrane manufacturers. Check with each company’s technical department for company-specific ratings.
