The Elevate UltraPly TPO Walkway Pad is a reinforced walkway composed of white thermoplastic material. The pad is produced into 30" (762 mm) wide by 50' (15 m) long rolls. The pad has a textured surface and a smooth bottom surface for easy welding to UltraPly TPO roof membrane. The walkway pad or acceptable paver is required at all access points (ladders, hatches, doorways, etc.), and is recommended in areas where necessary rooftop traffic will occur to help protect the roofing system from damage as follows:  As a walkway system on roofs subjected to traffic more frequently than once per month.  Around rooftop equipment that requires periodic maintenance.
