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. Extensive green roofs are delivered for a variety of reasons, the most popular being for biodiversity and meeting a Biodiverse Action Plan (BAP).

Why choose an extensive green roof from Bauder?

The most drought tolerant planting, therefore the thinnest and lightest system, uses sedum plant species. Bauder's SB Substrate Sedum blanket is the lightest GRO compliant system on the market.
