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. View the key findings and full study here.
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 of EverGuard Extreme® 60-mil Fleece-Back TPO 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.

- 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.
- Can also be used for ISO insulation applications.
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 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%,2 while reducing installed cost by up to 12%.
