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.
