Extensive Green Roofing systems consist of lightweight, naturalistic planting that provides extensive plant cover with minimal maintenance and a wide range of benefits, including:

  • Little modification of the roof environment, ensuring suitability for new or refurbishment applications.
  • Naturalistic style planting systems, that require minimal care, irrigation and maintenance.
  • A thin layer of lightweight growing mediums, typically between 65mm and 150mm.
  • A wide range of grass, herbaceous, succulent and moss species, that establish self-sustaining plant communities.
  • Suitability for use on roof slopes (from 0 to 35° slope), with measures possibly needed above 5° Pitches greater than 35° may be accommodated subject to design.


Typically weighing 80 to 90 kg m². (saturated system weight) lighter variations can be specified, but the membrane will require independent attachment.
