Sloping green roofs


  • Weight: 
    160-190 kg/m²
  • Depth: 
    13 cm
  • Roof pitch: 
    5-35° (9-70%)
  • Vegetation form: 
    Sedum / grass / herbs


For sloping roofs a system to prevent sliding is necessary. The drainage layer can be thinner and simplified due to the quicker runoff of rainwater. With a grass roof an irrigation system is required to keep the grass green even in the dry summer periods.
