NATURE ROOF
SOLUTION 1 (USING DRAINAGE BOARD): 0-5°
CHARACTERISTICS
- Multi-layered system using Optigreen Drainage Board.
- High level of biodiversity.
- High ecological value.
- A habitat for butterflies, bees and other insects.
- Long flowering window annually.
- Use of recycled plastic materials.
- Generally suitable for inverted roofs, if applicable. Minimum load for wind up-lift protection should be calculated.

Maintenance costs 
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. ** 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. -
Brief Description
Optigreen Vegetation Mat
- Pre-cultivated sedum and wildflower mat for the rapid establishment of vegetation in order to prevent wind erosion, with decomposable carrier
- Alternative: wildflower-based vegetation mats or plug planting
OPTIGREEN EXTENSIVE SUBSTRATE E (50 - 200 MM)
- A substrate with high water storage capacity and good air porosity, tailored to extensive multi layer systems.
- Mounds of up to 250 mm, as required, for increased biodiversity
