Wallbarn Aluminium Edge Trim for Green Roofs

The Wallbarn Aluminium Edge Trim is a sleek, practical solution designed to enhance the appearance and performance of any green roof system. Whether used with modular M-Tray® systems or traditional roll-out green roofs, this trim helps define borders, maintain structure, and ensure a clean, professional finish. This versatile trim is particularly useful where there is no parapet or raised upstand, acting as a neat barrier to contain pebble margins around the edges of the roof. In roll-out systems, it effectively separates vegetation zones from drainage areas, pebble borders, and rooflights—ensuring that materials stay exactly where they’re meant to. Made from right-angled aluminium, the trim fits snugly against the deck and is held in place by the weight of M-Trays®, gravel, or other roof finishes. It's both lightweight and durable, making it easy to install while offering long-lasting stability and visual appeal.

Key Benefits

Provides a crisp, clean edge to green roof systems Prevents movement of pebbles and planting media Suitable for use with modular or roll-out green roof designs Lightweight, weather-resistant aluminium construction Installs easily beneath M-Trays® or ballast materials Helps define zones and manage roof drainage effectively

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
