Wallbarn’s M-Tray is designed to create an instant green roof. M-Tray has been fully tested and now has a B ROOF t(4) classification. 

The superior vegetation in Wallbarn’s M-Tray is pre-grown in specially-designed modules for approximately six months at their dedicated UK nursery. Wallbarn have developed its own specially-designed substrate mix which means there is considerable root growth already in the tray. This ensures that by the time they are delivered the plants are strong, established and provide consistent cover over the intended area. 

The modules contain a carefully-selected mixture of flowering sedum and wildflower varieties, providing year-round greening and also different textures and flowers throughout the summer. A species list can be downloaded via the link above. 

The modules are highly portable and simply clip together, meaning they can be installed much faster than roll-out systems without any specialist landscaping or roofing knowledge. The M-Tray’s unique design means rainwater gets retained far longer and very little maintenance is required through the seasons.

Wallbarn sows a low-density amount of sedum species to give a year round green and good level of ground cover and adds, again from seed, a mix of wildflower species which contain the following characteristics:

  • They are low growing species with as much succulence as possible
  • They are all native to UK / northern Europe
  • They are perennial and hardy
  • They will grow in low nutrient substrates
  • They have proven to improve biodiversity

A few factors when considering wildflower roofs:

  • Flowers can grow tall and die back to leave dead grasses and stems, which can lead to a fire hazard
  • Wildflowers will not provide the same ground coverage or year-round greening of sedum roofs
  • Wildflowers take longer to grow and flower than sedum
  • Wildflowers often require 2 years before flowering and may not return year after year without re-seeding
  • Some wildflowers will not flower in certain years, performance depends heavily on the weather that year
  • Wildflower roofs require more maintenance than sedum roofs

The  sedum / wildflower ratio is designed to complement each other and provide variety and attractive spaces across the summer but also with a sufficient amount of coverage and “green” throughout the year.

Features:

  • No loose substrate on the roof 
  • No sharp aggregate damaging your waterproof membrane, blowing away or clogging up drains
  • Modules packed onto pallets for easy transportation
  • Ideal for areas with restricted access
  • Faster, easier installation
  • Expert knowledge not required for installation
  • Vegetation fully established with strong, healthy growth
  • Strong root structure reduces dependence on irrigation
  • An instant and sustainable green roof
  • Dimensions 500mm x 500mm x 100mm
  • 4 x trays per m2.
  • Weight 20kg (25kg when saturated)

Please note this is non-returnable.

This section is split into two parts, with advice about Wallbarn's pedestals range, as well as their green roof offering.

Pedestals

What are the advantages of pedestals?

They are quick and easy to install, offer improved drainage, protect the surface underneath and can be lifted at any time for maintenance.

How do I install them?

The pedestals are placed on a flat, hard surface, with no mechanical fixings required. They need to be placed on a structured surface, and shouldn't be placed on non-compacted earth.

Do they need to be fastened?

No, the pedestals are part of a suspended system, with the weight of the slabs/decking holding everything in place.

Green Roof

What is a green roof / modular roof?

Sedum or other succulent plants are grown in low-level substrates. Modular systems are grown in sections and can be lifted into place and joined together.

Do they need maintenance?

The plants are very hardy, but watering in extreme conditions is recommended. Dead leaves and vegetation should be removed at regular intervals, and a slow-release fertiliser can be applied at certain periods throughout the year.
