Product Documentation

Proven Performance An Aged TPO Field Study

After accelerated heat aging at 275ºF (135ºC) for 105 days, an independent study proved EverGuard® TPO showed no cracking -while almost every one of the competitors' samples failed! Guarantees are available up to 30 years when using EverGuard® TPO Fleece-back Membrane.¹ The large welding window makes it easy to install and it is complemented by the most complete line of accessories.

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%.
