System structures

System structure Purple Roof - stormwater management

Purple roof 0-30°
Flat and shallow pitched roofs are ideal for a green roof. The system structure for a water-retaining purple roof consists of a drainage layer with filterfleece, a needled (not hard board) mineral wool that retains 90%+ of water by volume, a specific non-proprietary soil recipe, and a vegetation blanket.

Steeply pitched green roof 30-40°
Sempergreen has the perfect solution for pitched roofs. The Sedum-mix blanket type T has plastic reinforcement top and bottom. This makes this vegetation blanket - in combination with the correct system structure - very suitable for (steeply) pitched applications.
