Green roof

Green roof drain

Good drainage and water handling are essential to green roofs

Properly designed drainage mat is critical for a successful installation, and brings environmental benefits.

OUR SOLUTION

Xeroflor’s drainage mats are engineered to divert excess water from the green roof quickly for healthy plant growth.

Exceptional flow rate and compressive strength

Exceptional flow rate and compressive strength

XF Drain’s 3D entangled filament profile design creates a 95%+ open path in all directions to divert excess water from the green roof quickly. The 3D core has high compressive strength, which support the weight of the plants and growing medium while providing high flow rate.

Ideal for Protected Membrane Roof (PMR)

The permeable filter fabric and the 95%+ open drainage core design permits free water vapor movement. This creates an air space above the extruded polystyrene rigid insulation and enables topside venting on PMR applications for long term thermal performance.

Ideal for Protected Membrane Roof (PMR)
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.

Environmentally friendly

XF Drain green roof drains contain a minimum of 40% by weight of recycled polymer from post industrial sources. Some options also include a water retention fleece made of 100% recycled polymer fibers to capture and store water, and manage stormwater runoff.
