The VersiFlex Mechanically Attached Roofing System incorporates 50-mil thick PolyesterReinforced VersiFlex Polyvinyl Chloride (PVC) membrane (white, gray) OR 50-mil thick Polyester Reinforced VersiFlex KEE HP (High Performance) Membrane (white, gray).
Either membrane is available in 10’ wide field sheets and 5’ perimeter sheets. Standard Polyester Reinforced membrane is also available in 81” wide field sheets and 40.5″ perimeter sheets. VersiFlex sheets are available in 75’ or 100’ rolls.
All sheets are mechanically attached over an approved insulation/underlayment to an acceptable roof deck with the appropriate Versico Fasteners and Fastening Plates. Adjoining sheets of VersiFlex membrane are overlapped and joined together with a minimum 1-1/2″ wide heat weld.
VersiFlex PVC is specifically designed for long-term performance and is highly resistant to fire and chemicals including acids, bases, restaurant oils and grease. VersiFlex white, tan, and light gray membranes are ENERGY STAR qualified and Cool Roof Rating Council (CRRC) certified. These things combined provide desirable levels of solar reflectance, thermal emissivity, and Solar Reflective Index (SRI).
