Extensive green roofs - Sedum roof systems

Extensive Green roofs are designed to be low maintenance, lightweight systems with no general access. Typically they have thin layers of substrate, the growing medium, to keep depth and weight to a minimum.
The most drought tolerant planting, and therefore the thinest and lightest system, uses sedum plant species. Bauder's SB Substrate Sedum blanket is the lightest GRO compliant system on the market.

Extensive green roofs are delivered for a variety of reasons, with a popular reason being for biodiversity and meeting a BAP.
