Firestone Building Products Company added several new TPO products to its QuickSeam™ accessory line, including the UltraPly QuickSeam Reinforced Mechanically Attached (R.M.A.) Strip, which offers non-penetrating intermediate attachment for roof perimeters. The strip is installed using conventional UltraPly TPO HD Seam Plates, metal or polymer batten strip. UltraPly QuickSeam Reinforced Perimeter Fastening (R.P.F.) Strip is installed using UltraPly TPO HD Seam Plates. The strip is a non-penetrating membrane attachment for securement at angle changes, which reduces in-seam attachment and welding. UltraPly QuickSeam Pipe Boots cover pipes ranging from 1 inch to 6 inches in diameter and requires no heat welding. QuickSeam Corner Flashing helps reduce installation time and labor and delivers a watertight flashing of roof system metal edges. For more information,
