EverGuard Extreme® TPO 60-mil Fleece-Back Membrane

Why EverGuard Extreme® TPO 60‑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® TPO showed no cracking - while every one of the competitors’ samples failed.

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 years1 and it’s easier to install due to the large welding window.

Benefits
Benefits of EverGuard Extreme® TPO 60-mil Fleece-Back Membrane include:

  • Great Value: Superior performance at a cost-effective price.
  • 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).
  • HPDs: Only single-ply roofing manufacturer that publishes Health Product Declarations (HPDs) for transparent reporting and LEED® v4 compliance.
  • EPDs: Publishes Environmental Product Declarations (EPDs) for Single-Ply Roofing Membranes.
  • NSF P151: Certification of Rainwater Catchment System Components.
Installation Options

EverGuard Extreme® 60-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.
  • Adhered Application: Can be installed with EverGuard® WB181 Bonding Adhesive (water based) or hot asphalt for the smoothest appearance.
  • Provides superior wind uplift performance.
  • LRF-O Adhesive: Two-part low-rise polyurethane foam adhesive that is low VOC and accommodates minor surface irregularities. Available in a cartridge or 5-gallon (18.9 liter) container.
  • LRF-M Adhesive: Two-part low-rise polyurethane foam adhesive that is low VOC and accommodates minor surface irregularities. Can also be used for ISO insulation applications. Available in a cartridge or 5-gallon (18.9 liter) container.
  • Two-Part Roofing Adhesive: Self-contained low-rise foam dispensing kit offering 20 squares per kit so there are fewer changeovers.
  • Cost effective since you don’t need spray equipment and no downtime/maintenance worries.
TPO Accessories

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® 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%2 while reducing installed cost by up to 12%.
