ABG - Extensive Green Roof Systems
Extensive green roof systems consist of a shallow layer of growing media, typically 80mm deep. This is planted with a variety of drought tolerant hardy plants such as sedums.
Extensive Green Roofs are the most common type of green roof and are relatively self-sufficient. They are not designed or constructed with the intention of being trafficked by pedestrians and whilst not providing any kind of amenity area, they do contribute to improving air quality, reduce the visual impact of the roof and assist in controlling rain water run-off / harvesting as well as improving the acoustic and thermal properties of the roof.
Extensive Green Roof Systems are characteristically lightweight, with saturated loadings ranging from 80 – 120kg per m2.
The ABG Extensive Green Roof System typically consists of a Roofdrain drainage & reservoir layer, a lightweight Extensive growing media, aluminium edge profiles and a vegetation layer.
