Fatrafol 804 Unreinforced Waterproofing Membrane is a PVP-P based PVC detailing component designed to maintain continuous watertight integrity within Fatrafol reinforced roofing systems.
This unreinforced membrane provides the superior elongation and pliability required for moulding around complex roof penetrations, skylight curbs, and tight internal corners where standard reinforced membranes are too rigid to ensure a reliable seal.
Certified to EN 13956 standards, it supports hot-air welding for permanent fused seams and remains workable in sub-zero temperatures as low as -5°C to prevent winter project delays.
