Description

The Aluminium Green Roof Edge Retention Trim PPC – 2.4m Length is designed for green and living roof systems where the roof perimeter needs a defined edge for retaining substrate or pebbles while allowing water to drain freely.

Made from 1050A aluminium, the trim provides a lightweight and durable solution for exposed roof applications. The profile has cut drainage slots to help water pass through the edge while helping keep loose substrate or pebbles within the green roof build-up.

Each section is 2400mm long and comes with a joiner for connecting adjoining lengths. The connectors can be used for straight joints and can also be bent to form internal or external angles where required.

The trim is available in 1.5mm and 2mm thicknesses, with several face depth options. The standard finish is mill finish, while polyester powder coating is available in a wide range of RAL/BS colours where a specific finish is required.

For related products, see the Living Roof Accessories range, which includes green roof inspection chambers and colour-coded fasteners alongside green roof edge retention products.

Key Benefits of Aluminium Green Roof Edge Retention Trim

  • Designed for green and living roofs – helps retain substrate or pebbles around the roof perimeter while allowing water to free-flow.
  • 1050A aluminium construction – provides a lightweight and durable solution for exposed roof applications.
  • Pre-slotted drainage design – the cut slots allow water to pass through while helping retain loose roof media.
  • Multiple face depths – available in several depths to suit different green roof edge requirements.
  • 1.5mm and 2mm thickness options – gives you a choice when specifying the profile for your project.
  • 2400mm length – provides a practical standard length for green roof perimeter runs.
  • Joiner supplied – each 2.4m length comes with a joiner for connecting sections.
  • RAL/BS colour options – polyester powder coating is available where the edge needs to coordinate with other external metalwork.
  • A2-s1,d0 fire classification – provides a defined fire classification for specification purposes.
  • Suitable for different applications – designed for industrial, domestic and commercial projects.
  • UK fabrication – designed and fabricated in the UK.

  • 100% recyclable aluminium – aluminium can be recycled at the end of its service life.

Why Green Roof Edge Retention Matters

The edge of a green roof needs to retain the roof build-up without preventing the intended flow of water.

A purpose-made retention trim creates a defined perimeter around the planted area. Its slotted design allows water to pass through while helping keep substrate or pebbles within the roof system.

For architects, developers and roofing contractors, selecting the correct face depth, base size and thickness at the specification stage helps ensure the edge detail is suitable for the planned roof build-up.

Installation Notes

What to Check Before Ordering

Before ordering the Aluminium Green Roof Edge Retention Trim, consider:

  • Required face depth
  • Required thickness
  • Base size
  • Total roof perimeter
  • Green roof build-up
  • Internal and external corner requirements
  • Required finish or RAL/BS colour

The trim is typically used within living roof applications for substrate or pebble retention while allowing water to free-flow. Adjacent lengths can be connected using the pre-slotted aluminium connector. The product is suitable for both new builds and existing properties.

Measure the total perimeter before ordering so you can work out how many 2.4m lengths are required. Also allow for the required joints and any changes in direction around the roof perimeter.

For project-specific requirements or bespoke solutions, you can Request an Estimate with your measurements or drawings.

If you are specifying a powder-coated finish, the Product Policy provides additional information about powder coating and made-to-order products.
