Elevate UltraPly™ TPO XR combines the durability of a single-ply membrane with an external backing of eight-ounce, non-woven polyester to offer an additional internal and external reinforcement for puncture resistance. Installation flexibility enables the roofing system to be installed with either hot asphalt, Elevate UltraPly TPO XR Bonding Adhesive, foam adhesive XR Stick, or ISO Spray S.
