  • Design Notes & Considerations

    General Notes

    The Icopal ST Lawn Turf intensive green roof system is suitable for both new build and refurbishment projects. Generally installed on flat roofs to a fall, but can be installed on roofs with shallow pitches where a retention system is required. All slopes over 5° will require a mechanically fixed eaves edge restraint.

    Irrigation

    Initial: Irrigation is required immediately after installation, until the turf is fully established. This could be for a period of up to 8-12 months. During the establishment period irrigation should be frequent to keep the substrate moist.

    Once established: It is highly recommended that a suitable permanent irrigation system is installed to ensure the turf survives periods of hot dry weather. Pitched roofs retain less water and so will require additional irrigation.

    Water Source: A roof top source with a pressure of 2.5 – 3 bar and a flow rate of 60 L/min is recommended to connect a temporary system if required.

    Maintenance

    As with terrestrial lawns, the grass will need regular mowing during the growing season. However it can be left to grow longer if required to produce a grass “meadow” look.

    Weeds should be removed periodically through the year to reduce the likelihood that they become dominant. It is recommended that a suitable fertiliser is applied to keep the grass healthy. This may be a spring feed of slow/controlled release fertiliser to last the growing season, or more regular granular/liquid feeds throughout the growing season.

    Detailing

    A border with a recommended width of 300 – 500 mm of washed river stones (20 – 40 mm diameter) should be used around all roof penetrations, outlets, perimeters and system edges to provide a vegetation free zone.
