GenFlex TPO membrane was introduced in 1996 and is manufactured at our state-of-the-art extrusion technology facility in Muscle Shoals, Alabama, where we have produced the industry’s first 12-foot wide sheet meeting industry code requirements.

The 12-foot wide sheet offers significant benefits including fewer seams to weld and fewer panels to install. With fewer seams and fewer panels for most applications, there is a significant cost advantage to a 12-foot fully adhered system. Compared to a 10-foot system, the wide sheet application requires 16% fewer seams—33% fewer than an 8-foot system, and 50% fewer than a 6-foot system.

GenFlex TPO membrane, a high quality thermoplastic polyolefin, offers the “best of both worlds”...the proven flexibility and weathering resistance of rubber and the performance of hot-air welded thermoplastic seams. GenFlex TPO membrane meets all the requirements of the new TPO ASTM Standard D 6878-03.

Heat-welded thermoplastic roofing membranes are the fastest growing segment of the low-slope roofing market and GenFlex TPO is an excellent system choice. GenFlex TPO roofing systems are designed for durability and to withstand extreme environmental exposure. GenFlex TPO systems offer the widest selection in both product and system types. From dual weld seams to Peel & Stick systems, GenFlex has the TPO products you need for mechanically anchored to fully adhered systems with warranties up to 20 years depending on the system design.

GenFlex TPO membranes are produced with a minimum top ply film thickness of 15 mils over scrim. This top ply has outstanding weathering and welding characteristics in addition to a smooth finish designed to resist dirt accumulation for long-term aesthetics.

Introduced in 2003, the GenFlex Peel & Stick™ TPO Membrane System is truly a revolutionary new era in roofing. Peel & Stick TPO membranes and accessories have pre-applied adhesive and tape, making installation faster, easier, safer and smarter.

No application of bonding adhesive means little or no solvent fumes for crews and no exposure to building occupants during installation. This new Peel & Stick technology can also eliminate the need for generators and walker welders which also add up to greater economy and efficiency
