The three roofs installed total 125m2 of sedum roofing from Bauder.
The extensive sedum green roof enhances the sustainability of this new development of the assessment unit at St Peter’s Hospital Chertsey.
Extensive roofs mostly comprise self-sustaining, low-growing plants, which are frost and drought tolerant, such as mosses, succulents, herbs and grasses, with bulbs and tubers.
The most commonly used plants on extensive roofs are sedums, as demonstrated in this project.
Benefits of sedum
A sedum roof brings some biodiversity benefits by providing nectar for pollinators, along-with nesting opportunities, shelter and food for bees, butterflies and other insects.
