The advances made in the design of the new M-Tray® model have created a number of key advantages including:
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.
The main advantages of modular over roll-out green roof systems include convenience and speed of installation, futureproofing, and the delivery of instant results.
All the elements required for a successful green roof have been measured and 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 is 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.

The installation of timber decking to a roof can pose a number of problems with accessibility being a significant issue for many decking projects.
The range of hardwood timber tiles available from Wallbarn is absolutely ideal for installations with very limited height thresholds and are perfect for areas which are inaccessible for other decking products (longer planks).
All our timber possesses the following qualities:-
Many projects face issues relating to accessibility and time constraints but because our timber decking tiles measure just 500 x 500mm they can easily be carried by hand to ensure their suitability for even the most inaccessible of areas.
Hardwood timber tiles offer an easy way to lay attractive decking onto rooftops and terraces.
The key benefits include:
Whilst traditionally laying timber decking directly onto these deck surfaces led to additional costs of employing specialist carpenters and laying timber joists directly onto the waterproofing membrane also risked damage over time, our timber paving tiles have been specifically designed to offer the perfect solution as the weight of the tile will hold the system in place.
This suspended system avoids having to fix anything onto the deck and lifts all the timber away from any standing water, avoiding the dangers of a slippery surface.
Because everything is free-standing, the tiles can be taken up and replaced without disrupting the whole area, should the deck need to be inspected. Unsightly items such as drainage outlets, cables and pipes can be hidden beneath the tiles and accessed easily.
Stunning finishes can be achieved. The tiles can be laid in a straight line pattern or in a “chessboard” style, depending on the client’s wishes. We have a range of different timber available sourced from South America, chosen for their beauty and durability.
An urban heat island, or UHI, is a metropolitan area which is much warmer than the surrounding rural areas.
“The annual mean air temperature of a city with 1 million people or more can be 1.8–5.4°F (1–3°C) warmer than its surroundings. In the evening, the difference can be as high as 22°F (12°C). Heat islands can affect communities by increasing summertime peak energy demand, air conditioning costs, air pollution and greenhouse gas emissions, heat-related illness and mortality, and water pollution.”
Heat is generated by energy from all the people, cars, buses, and trains in big cities like London, Paris and New York. Urban heat islands are typically then created as a by-product of this in areas that have lots of activity and lots of people.
There a variety of different reasons why UHIs come into effect. For example, when houses, shops, and industrial buildings are built close together, it can create a UHI. Building materials are usually very good at insulating, or holding in heat. However, because of the insulation, the areas around the buildings become warmer.
“Waste heat” also contributes to a UHI. People and their tools, such as cars and factories, are always burning off energy, whether they’re jogging, driving, or just living their day-to-day lives. The energy people burn off usually escapes in the form of heat. And if there are many people in one area, a lot of heat will be created.
Urban areas are densely populated, meaning there are a lot of people in a small space. Urban areas are also densely constructed, meaning buildings are constructed very close together. When there is no more room for an urban area to expand, engineers build upward, creating skyscrapers. All this construction means waste heat—and heat that escapes insulation has nowhere to go. It lingers in and between buildings in the UHI.
Nighttime temperatures in UHIs remain high. This is because buildings, pavements, and car parks block the heat coming from the ground from rising into the cold night sky. Because the heat is trapped on lower levels, the temperature is warmer.
Urban heat islands can have worse air and water quality than their rural neighbours. UHIs often have lower air quality because there are more pollutants (waste products from vehicles, industry, and people) being pumped into the air. These pollutants are blocked from scattering and becoming less toxic by the urban landscape: buildings, roads, sidewalks, and parking lots.
Water quality also suffers. When warm water from the UHI ends up flowing into local streams, it stresses the native species that have adapted to life in a cooler aquatic environment.
Scientists are studying how urban heat islands might contribute to global warming, the most recent climate change pattern that includes the gradual warming of the Earth’s temperature.

The installation of green roofs to a UHI has been proven to help offer a way to combat the effects.
Our M-Tray® has been specifically designed to make sedum roof installation quick and easy – with minimum disruption to the plants and the structure they are going onto – and to provide a seamless, verdant finish – an instant and sustainable green roof.
The benefits of constructing a green roof include:
