Description

The green roof with great leeway in substrate height and biodiversity

Many cities and municipalities have now developed green concepts in which it is not only stated that roofs should be greened, but in some cases also how. In many cases, there are already minimum requirements for substrate heights so that a correspondingly higher plant diversity can settle permanently. In the field of extensive to simply intensive green roofs, the NATURDACH system is the form of green roof that offers a great deal of leeway in terms of substrate height and biodiversity and can thus also achieve the highest ecological value.
