45-mil Membrane

Why EverGuard® TPO 45-mil Membrane?

EverGuard® TPO outperforms its competitors in heat-aging and UV tests—the best predictors of TPO performance. After accelerated heat aging at 275°F (135°C) for 105 days, EverGuard® TPO 60-mil showed no cracking—while almost every one of the competitors’ samples failed! Guarantees are available up to 20 years when using EverGuard® TPO 45-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 45-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 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.


EverGuard® TPO 45-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 and installed practically year-round. 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® 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® TPO pre-fabricated 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%.
