Comparing ul class a fire ratings with isocyanurate insulation as the substrate the tpo membrane has a maximum slope of 0 5 inch in 12 the pvc is at a 2 in 12 and the epdm achieves a class a at a 0 5 inch in 12 for unreinforced adhered membranes and 0 75 inch in 12 for reinforced mechanically attached membranes.
