M-Trays® Modular green roof system

Wallbarn

Wallbarn produces an extensive sedum modular green roof system called M-Tray® .

M-Tray® is a pre-grown, fully established sedum green roof loaded into a portable tray, for easier transport and faster installation of green roofs.

All the growing, filtration and drainage elements are included in the system and the shape of the modules means that each one is simply laid onto the deck and clipped to the next module to create one seamless, fully established green roof.

The major benefit of M-Tray® is flexibility. Getting it to the roof is not a disruptive and costly process, which is a huge advantage over loose lay systems. Each module can be carried by hand to areas where it is simply not possible to loose lay roll-out systems layer-by-layer. M-Tray® can reach the roofs other systems cannot reach.

Access to the roof deck is future-proofed. If there are problems with the membrane beneath or inspection is required, one M-Tray® or a section can easily be lifted out without major disruption. This is in contrast to loose lay systems, where tonnes of loose substrate will need to be dug out and the whole area may need to be destroyed.

Each M-Tray® is 500mm x 500mm x 100mm deep. Each tray unit clips into its neighbour at four points. The sedum grows above this level to hide the joints. This interlocking system means that each M-Tray® is fitted securely with no need for sharp fixings going through the waterproofing beneath. The sedum growth is not restricted and can mingle across the whole area. Irrigation systems can be installed in conjunction with the trays.

The M-Tray® modules are pre-grown in Wallbarn's UK nursery. The empty modules are made from recycled polypropylene and are manufactured with an angled base which creates a large surface area for the roots to establish. The module is filled with a bespoke substrate mix developed exclusively by Wallbarn with zero peat or brick or concrete particles. It has been developed to encourage long-term plant growth and provide sustainability. .

The sedum is planted into the substrate from seed. We use a mix of many different flowering species of sedum suited to the UK climate, to ensure all-year growth, flowers and biodiversity to attract wildlife with variation throughout the summer, durability and ability to be resistant to periods without rainfall.

M-Tray®:

The vegetation is grown into the M-TRAYS over a 12 month period to ensure strong, well established, healthy plants, fully integrated into the intermediate layers with solid root structures. This means less shock or bedding-in time when installed, less risk of wind uplift or erosion and ensuring an instant, mature green roof.
