The Sempergreen® Lightweight sedum green roof system is a unique product, that allows you to create your own green living roof.

Suitable for use on flat roofs from 3º to 15°, the substrate layer is 40mm thick and has excellent water absorption qualities. There are 6 – 8 different species of hardy succulents, each chosen for their ability to absorb and retain water and to thrive in adverse weather conditions.  The sedum blankets in our Lightweight system provide at least 95% plant coverage. Minimum order 10m2.

If you are creating a gravel border around the roof edges, sky lights, lanterns or drainage areas, it is important to add an additional amount of drainage layer to sit beneath the gravel.

Ideal for: Lighter weight roof loading requirements, domestic & commercial buildings, flat roof extensions up to 15°, water attenuation requirements, garden rooms, garages, bike & bin stores.
