Metal Edging For Green Roofs

July 21st, 2020

Aluminium edging is designed to improve the aesthetic finish of your green roof and also to create a separation between the vegetation and areas such as drains and the roof lights.

Parapets and upstands should be kept clear of plants, to avoid roots clogging outlets and vents, and to reduce fire risk.

  • An aluminium angle can be installed around your green roof modules both to improve the aesthetic finish of your green roof and also to create a separation between the vegetation and areas such as drains and roof lights
  • The aluminium profile is right-angled where it meets the deck, so it can sit underneath and be weighed-down either by the M-Trays® themselves or by pebbles which are recommended anyway as a fire break
  • It can be mechanically fixed to the surface beneath. Or, if this a waterproofing membrane, the angle can simply be ballasted by placing your M-Trays® on top
  • Where there is an exposed edge with no parapet, the perforated aluminium angle can be used to provide an edge to the green roof itself. The pebbles are then installed on the other side. This ensures the free flow of drainage water.

Aluminium edging bars are available in various heights including 50mm, 75mm, 100mm, 150mm or 200mm high to create a clear, straight edge to the vegetation, holding it in place whilst still allowing free drainage.

Our edging bar can be powder-coated bespoke colours to meet your project’s requirements.

This product is in accordance with the GRO code of practice for green roof construction.
