Nature Roof System Solution

TECHNICAL DATA

Weight *: 100-300 kg/m² or 1.0-3.0 KN/m²

Build-up depth: 100-250 mm

Roof pitch: 0-5° (0-9 %)

Vegetation form: herbs, wildflowers, grasses, sedum

Water retention: 60 - 70 %

Discharge coefficient **: C=0.56 - 0.27

Water storage: ca. 30 - 80 l/m²

Discharge yield ***: 81-168 l/s x ha

* 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.

** Depends on slope and system solution. Determined at 0° according to FLL guidelines.

*** Determined according to FLL discharge coefficient measurements using a 15-minute reference rainfall r(15) = 300 l/s x ha.
