Aluminium Edging Trim with drilled holes
High quality water-permeable aluminium edging trim, ideal for use as green roof edge trim and in landscaping. The trims are designed to go around the perimeter of a roof to help contain mass materials such as the growing substrate of a living roof.
The one metre lengths are ultra-convenient and easy to handle. They feature drilled holes to allow water to drain easily.
Uses of Aluminium Edge Trim
These edge trims can be used in the following situations:
- a separator between the substrate/pebble strip and the open edge of the roof
- water-permeable upstand at the eaves edge of roofs up to max. 5° roof pitch (e.g. car ports, bike sheds) and flat roofs
- garden landscaping
Note: These edge trims are not suitable for use as a structurally effective gravel retainer in the pitched roof area < 5° RP.
Green roof edge trim
These aluminium edging trims are ideal for green roofs. At a one metre length they are easy to install and ideally suited to smaller perimeters, acting as a green roof edge restraint. The strips enclose the vegetation as well as a border of pebbles that help prevent any roots or other material blocking the drainage holes.

Installing aluminium edge trim
The edge trims are designed to go round the perimeter of a flat roof if there isn’t already an upstand. The one metre lengths can be joined together with an edge trim connector that effortlessly connects the strips together.
Corners are created by cutting the aluminium 1m lengths with tin snips or an appropriate tool and bending to the desired angle. This allows different angles to be formed that suit the specific layout. Please see images.
The perimeter border pebbles will sit on the base of the edge trim and the PermaSEAL Root Barrier & Separation Membrane can be cut to form a barrier between the pebbles and the growing medium. This prevents the growing medium/vegetation clogging up the pebbles and edge trim.
