OUR UNIQUE MODULAR GREEN ROOF SYSTEM

What is the M-Tray®?

A green roof system consisting of modular trays containing superior substrate and established sedum plants nurtured from seed at our own UK nurseries.

What makes the M-Tray® unique?

  • deep cavities for healthy roots
  • optimum drainage means stronger plants
  • established vegetation at point of installation
  • 100mm deep substrate for longevity of plant life
  • no sharp edges or mess, less risk to membrane
  • click-together trays create seamless connection
  • easy to transport and install

 

Our unique M-Tray® has been specifically developed to make sedum roof installation that much easier with minimum disruption to both the plants and the structure it is going onto.

The M-Tray® is designed to give a seamless, verdant finish – an instant and sustainable green roof.

Check out some of the varied projects where our M-Trays have been installed recently:

We only supply fully established, mature sedum plants contained within our easy-to-carry M-Trays® which click together to form an almost invisible join.

The M-Tray® unit has been designed and developed by Wallbarn in the UK and is the subject of Community Registered Design (No. 002953943-0001) and US Design (Application No. 29/553,129).

The sedum plants are grown from seed to maturity at our UK nurseries. 

Wallbarn is at the forefront of developments in the green roofing sector and has always provided products that combine top quality ingredients with user friendly, hassle-free maintenance. 

MODULAR vs ROLL-OUT BLANKET
  • convenience and speed of installation
  • future-proofing your roof
  • instant results

All the elements required for a successful green roof have been measured and pre-installed into the M-Tray® modules at the nursery.

Users can feel confident that the plants, growing medium and filtration components are suitable and compatible, and at the correct level to give strong, healthy growth over the long-term.

The trays are grown for a period of at least 6 months and all will have been through at least one spring growing season; so the plants are well established, healthy and strong, and fully integrated into the substrate (unlike sedum blankets, which are not).

Mess and disruption are big issues with roll-out systems.

 

 

Moving bags of aggregate-based substrate onto rooftops is fraught with risk – the aggregate goes everywhere and as it is so granular, it can damage waterproofing membranes very easily. Sedum blankets are also supplied rolled up, so the plants get damaged during the transport and installation process.

This is not the case with the M-Tray® modules.

Another key benefit is accessibility. As each module is 500 x 500mm, one M-Tray® can be carried by one operative. For areas which are very difficult to access, such as single storey extensions, domestic projects and other completed structures, roll-out is simply not possible. M-Tray® can be hand-balled into even the most awkward areas, even carried through a window (pictured) if necessary. They are the perfect retro-fit product.

Speed is also a major factor. It has been proven that green roofs constructed using Wallbarn M-Tray® are installed much faster than in traditional roll-out methods.

It is also an instant green roof. Since the sedum are less shocked by the installation process, as soon as the trays are connected together the whole area is filled with well-established plants. They will start to grow straight away, forming a seamless layer of vegetation much faster.

Access to the roof is future-proofed. If there are problems with the deck beneath or inspection is required, one M-TRAY® or section can easily be lifted out without disruption to the whole roof.

The modular green roof panels are packaged and delivered in the most convenient manner.

By being palletised, the plants can get to the roof quickly and without the risk of damage. 

M-TRAY® with Wildflower

As well as the sedum trays, Wallbarn plants up a wildflower mix into the M-Tray®. A varied mix of at least six different native species has been selected. All these flowers and herbs are low growing, hardy species, chosen to be pollinators for butterflies and bees.

EXPORT & LICENSING OPPORTUNITIES

As well as supplying live products for installation on UK green roofs and landscaping spaces, Wallbarn is committed to M-Tray® as an export product.

We can supply the modules as empty trays for local landscapers worldwide to plant up and propagate according to the local climactic conditions and their own markets.

Licensing opportunities are available for both the M-Tray® brand and the mould, which can be granted to specific partner companies across the globe.

M-Tray® has been designed and developed by Wallbarn in the UK and is the subject of Community Registered Design (No. 002953943-0001) and US Design (Application No. 29/553,129). Further worldwide design registrations are currently being carried out.

An M-Tray® “Bible” is available to guide partners in the growing and installation process and we have drawn on many years of experience to create this publication.

Our aim is to get more green spaces into urban centres worldwide. With M-Tray® this is a possible and economically viable prospect. Join us in our vision.
