EverGuard® TPO 80-mil Membrane

Why EverGuard® TPO 80‑mil Membrane?
EverGuard® TPO outperforms its competitors in heat-aging and UV tests-the best predictors of TPO performance.

An independent TPO Study proves:

After accelerated heat aging at 275°F (135°C) for 105 days, EverGuard® 80-mil TPO showed no cracking-while almost every one of the competitors’ samples failed! Guarantees are available up to 30 years when using EverGuard® TPO 80-mil Membrane.1 The large welding window makes it easy to install and it is complemented by the most complete line of accessories.

Benefits of EverGuard® TPO 80-mil 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
  • 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.
Installation Options

EverGuard® TPO 80-mil Membrane has a versatile application method and is suitable for all types of single-ply systems:

  • Mechanically Attached Application: A quick and cost-effective system that can be installed practically year-round.
  • RhinoBond®3 Application: Can be applied without using adhesives.
  • Qualifies for the same guarantee length as an adhered system.1
  • Adhered Application: Can be installed with EverGuard® 1121 Bonding Adhesive (solvent-based), EverGuard® Low VOC TPO Bonding Adhesive, or EverGuard® WB 181 Bonding Adhesive (water-based) for the smoothest appearance.
  • Provides superior wind uplift performance.
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%.
