Fatrafol 804 is an unreinforced PVC membrane used for detail work inside Fatrafol reinforced roofing systems: flashing, corners, penetrations, and joining strips. It hot-air welds to Fatrafol 807 and 810 sheets to give one continuous waterproof layer.
UV resistant, and it can be installed in cold conditions down to minus 5 degrees Celsius. Meets EN 13956. It is a system component, not a standalone roof membrane, and it needs a trained installer with welding equipment.

UV resistant for exposed roof service. Installs down to -5C.
Meets EN 13956.
Cut and shape the 804 sheet for the detail, then hot-air weld it to the surrounding reinforced membrane per the Fatrafol system specification. Overlap widths and weld temperature follow the system datasheet.
System component only: not a standalone roof membrane. Installation by trained professionals with hot-air welding equipment.
