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)
Get the performance beyond an 80 mil TPO in a 70 mil product
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 70 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%.
