PITCHED ROOF
5-15° (WITHOUT ANTI-SLIP SYSTEM)

CHARACTERISTICS

  • Permanent solution for pitched green roofs without a specialised Anti-Slip System.
  • For roof lengths greater than 6 metres, an Anti-Slip System may be required (sublect to individual project assessment).
  • Varied substrate depths and vegetation forms possible.
  • Generally suitable for inverted roofs, if applicable.
  • Minimum load for wind up-lift protection should be calculated.

Cost factor
*Depending on the load capacity of the substructure, Optigreen "High Density (HD)" or "Low Density (LD)" substrates can be used. Weight specifications refer to saturated conditions; dry weight is approximately 60 - 70 % of the saturated weight.
**Optigreen Anti-Slip Systems need to be used in case the roof pitch exceeds 15°.
