EverGuard Extreme® TPO

70-mil Fleece-Back Membrane

70-mil Fleece-Back Membrane

Why EverGuard Extreme® TPO 70-mil Fleece-Back Membrane?

An independent TPO study proved:

EverGuard Extreme® TPO is the best performing TPO in accelerated aging. After accelerated heat aging at 275°F (135°C) for 190 days, EverGuard Extreme® 50-mil and 60-mil TPO showed no cracking — while every one of the competitors’ samples failed. View the key findings and full study here.

Factory-applied polyester fleece provides additional protection to the membrane and means you won’t need a slip sheet when re-covering over a variety of roofs. The fleece-back also provides enhanced puncture resistance, especially in areas more prone to hail. It increases installation efficiency 2–3 times when installing fleece-back TPO with GAF Two-Part Roofing Adhesive (compared to standard TPO adhesives). Guarantees are available up to 30 years and it’s easier to install due to the large welding window.2


Benefits of EverGuard Extreme® 70-mil Fleece-Back TPO include:

  • Excellent Seam Strength:  Heat-welded seams provide greater seam strength to taped and other seams.
  • Long-term Weathering:  Excellent long-term heat and UV resistance.
  • Energy Saving:  Highly reflective and emissive white roof can help reduce energy costs and urban heat island effect.
  • CREST Energy Savings Calculator:  See your potential savings at cool.gaf.com.
  • NSF/ANSI 347:  Providing architects and contractors with a certified sustainable option for single-ply roofing membranes.
  • UL Landfill Waste Diversion Validation:  Zero Waste to Landfill (Mt. Vernon TPO Plant).

EverGuard Extreme® 70-mil Fleece-Back TPO can be installed with a wide range of applications:

  • Mechanically Attached Application:  A quick and cost-effective system that can be installed practically year-round.
  • RhinoBond®1 Application:  Can be applied without using adhesives and installed practically year-round. Qualifies for the same guarantee length as an adhered system.2
  • Adhered Application:  Can be installed with EverGuard® 1121 Bonding Adhesive (solvent-based), EverGuard® Low VOC TPO Bonding Adhesive, or EverGuard® WB181 Bonding Adhesive (water-based) for the smoothest appearance. Provides superior wind uplift performance.


Field fabrication of TPO accessories is time-consuming, costly, and inconsistent – and it can lead to unreliable details that compromise a watertight roofing system. EverGuard Extreme® TPO prefabricated accessories deliver consistent quality and eliminate the worry and problems often associated with field fabrication. They can also boost productivity up to 200%,3 while reducing installed cost by up to 12%.
