60-mil Fleece-Back Membrane

Why EverGuard® TPO 60-mil Fleece-Back Membrane?

The factory-applied polyester fleece provides additional protection to the membrane including no need for a slip sheet when re-covering over a variety of roofs and enhanced puncture resistance, especially in areas more prone to hail. Efficiency increases 2–3 times when installing fleece-back with GAF 2-Part Roofing Adhesive (compared to standard TPO adhesives). Those benefits along with heat-welded seams, a high reflectivity, and how simple it is to repair and install make it the right choice for your job.

EverGuard® TPO outperforms it 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, an independent study proved EverGuard® 60-mil TPO showed no cracking—while almost every one of the competitors’ samples failed!  View the key findings and full study here. Guarantees are available up to 25 years when using EverGuard® TPO 60-mil Fleece-Back Membrane.1 The large welding window makes it easy to install and it is complemented by the most complete line of 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 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%.
