XF Drain

high-performance, sustainable green roof drainage

    OVERVIEW

    XF Drain - highly permeable geo-composites that combine drainage, filter, aeration and water retention functions in one product.

    Always clear, never clogged

    Always clear, never clogged

    Depending on the version, we incorporate a non-woven filter fabric to one or both sides of the drain core. This also protects the roof membrane and supports the vegetation, promoting drainage and root aeration. We can also add an optional retention fleece to provide water and nutrient storage.

    Maintain open diffusion in Protected Membrane Roof (PMR)

    XF Drain is 95% open thanks to its 3D fused, entangled filaments core and permeable filter fabric, which facilitate water and vapor movement. This enables topside venting and maintains open diffusion above the extruded polystyrene rigid insulation, therefore suitable for PMR applications.

    No fabric intrusion under soil conditions

    No fabric intrusion under soil conditions

    XF Drain consists of a 3D entangled polymer filament core that is thermally bonded to one or two fabrics. Unlike dimpled drains, XF Drain's design configuration prevents fabric intrusion under load and maintains high flow rate under soil conditions.

    Quick and easy to Install

    XF Drain is lightweight, flexible, lays perfectly flat for quick easy installation. The textile-based mat cuts easily, fits to curves and contours, and does not create sharp edges when cut.
