Great Value — Superior performance at a cost-effective price
Superior 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
Versatile Application Method
Factory-applied polyester fleece provides additional protection to the membrane offering a variety of benefits, including:
Increases installation efficiency 2–3 times when installing fleece-back TPO with GAF 2-Part Roofing Adhesive (compared to standard TPO adhesives)
Best performing TPO in heat aging and UV tests—the best predictors of TPO performance
Guarantees are available up to 30 years when using EverGuard Extreme® Fleece-back TPO 60 mil Membrane*
High 3-year aged reflectance of 0.72 can help reduce energy costs
Easier to install due to:
EverGuard Extreme® Fleece-back TPO can be installed with a wide range of applications:
Mechanically Attached Application... for 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 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 container
2-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. Can also be used for ISO insulation applications.
Field fabrication of TPO accessories is time-consuming, costly, and inconsistent, and 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%,** while reducing installed cost by up to 12%.
