Extensive Green Roofs – An Ecological Alternative to Conventional Surface Protection

Extensive landscaped roofs are an ecological alternative to conventional surface protection or ballast layers such as gravel and pavers. They are lightweight and have a shallow build-up height. Suitable plants include various Sedum species, herbs and some grasses. After establishment of the vegetation, the maintenance is limited to one or two inspections a year.

If designed specifically to increase the biodiversity and attract a particular fauna and flora, they are called “Biodiverse Green Roofs”. Biodiverse green roofs reproduce natural habitats and attract flora and fauna into the area, e.g. by providing food, nesting opportunities or resting places for creatures, such as spiders, beetles, butterflies, birds, etc.

Characteristics

  • Adapted plant communities
  • Minimal maintenance required
  • Supply of water and nutrients mostly by natural processes
  • Shallow build-up height
  • Weight approx. 50–150 kg/m²

System Build-ups

System build-ups at a glance

Inverted Green Roofs

In contrast to conventional flat roof build-ups, the inverted roof is characterised by a reverse arrangement of layers. The waterproofing is applied directly onto the load-bearing roof structure. The thermal insulation layer follows on top.  As a result, the waterproofing is perfectly protected against mechanical damage.
Technical Data
Build-up height ca. 110 mm
Weight, saturated ca. 120 kg/m²
Water retention capacity ca. 36 l/m²
