Versico's PVC Heat Weldable Walkway Roll is designed to protect the VersiFlex PVC membrane in those areas exposed to repetitive foot traffic and other hazards. PVC Walkway Rolls provide a defined path to walk on for those servicing and repairing HVAC systems and other rooftop equipment found on low-slope roofs. Walkways must be installed at all traffic concentration points regardless of traffic frequency. Walkways must also be installed if regular maintenance is necessary to service rooftop equipment.
