+44 (0)203 5899400 Website

Application

Retention Roof Meander FKM 30:

Greatly reduced drainage peaks.
For extensive green roof structures.

Retention Roof Meander FKM 60:

Greatly reduced drainage peaks.
Long-term water storage (meander 60).
For extensive and semi-intensive green roof structures.

Retention Roof Flow Control Extensive:

Very low outflow rate, thanks to a specifically adjusted flow control unit.
High retention volume in the WRB 80F approx. 75 l/m².
Lightweight thanks to hollow-body drainage unit (Water Retention Box WRB).
High evaporation capacity thanks to integrated capillary system.
Basic prerequisite: 0° roof.
Suitable for inverted roofs.

Description

With the retention roof systems, green roofs and intelligent rainwater management work together effectively and sustainably. For a better microclimate and in line with the concept of the sponge city. Optigrün offer effective solutions for delaying runoff and complying with discharge restrictions or throttled runoff from the green roof.
