Sempergreen® Super Lightweight Green Roof System

Minimum order 10m2

This system includes 3 layers:

  • Sedum blanket
  • Lightweight substrate roll 20mm
  • Drainage

The Sempergreen® SUPER 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 3° to 15°, the substrate layer is 20mm 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 Super Lightweight System have 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 drainage layer to sit beneath the gravel.

Ideal for: Lighter roof loading requirements such as flat roof extensions, garden rooms, sheds, garages, bike & bin stores. Can also be used commercially.
