Wallbarn M-Tray - Modular Green Roof System
The M-Tray modular green roof system by Wallbarn is a specialized roofing system designed to integrate greenery into urban environments. Developed in the UK, this product features trays measuring 500mm x 500mm x 100mm, arranged in a modular format for ease of installation and maintenance. The system is praised for its robust design, including fire-rated B ROOF t4 classification, and its ability to be removed without disrupting the entire roof structure. The modules boast a mix of sedum and wildflower vegetation, promoting biodiversity and enhancing urban aesthetics. Engineered to mitigate environmental impacts like the urban heat island effect, it also contributes to improved air quality and reduced stormwater runoff. The M-Tray® system supports a green roof depth to enable insulation and foster wildlife habitats, proving itself both ecologically and economically beneficial. Designed for versatility, it accommodates various architectural needs, from residential to commercial applications, and offers export and licensing opportunities worldwide.

Shape
- Module measures 500 x 500 x 100mm
- 4 x units make up exactly 1sq metre making estimating far easier
- Carefully spaced drainage holes ensure modules retain water for longer, allowing plants to absorb more rainfall, increasing attenuation and delaying discharge into outlets
- Design ensures even greater water retention at edges of module, preventing sedum from dying back at the edges.
- Stronger plant growth at the edges creates a more seamless layer of vegetation when the modules are connected
- Four gently ridged hand grips are positioned to enable installers to carry each module easier
Smooth edges & connecting bracket
- The connecting brackets are designed to give a tight connection, with the minimum gap between each module
- The joint is only 6mm so the plants will grow over it quickly, making it disappear in ultra-quick time
- The corners of the modules are rounded and smooth, so no sharp edges (which might puncture the membrane beneath) are present – this also makes handling the trays easier and the edges can be mounted onto Wallbarn pedestals if additional height is required
Trims & Edging
100mm aluminium edge trims and connectors fit neatly onto the sides of the modules. Fixings are designed to slot together neatly although they are not always necessary.
