The Extensive Natural Meadow system design is an appealing green roof solution due to its colourful vegetation and a diverse range of species. The basic system design of at least 10 cm can be partially increased to 25 cm to boost the different types of vegetation. The greater diversity of plants also encourages a variety of diverse habitats. Therefore, this green roof system is ideal as a biodiversity space and predestined for sustainable green roofs.
