Wallbarn have provided their sustainable M-Trays® for a green roof at a home in Whitstable.

M-Trays® simply clip together meaning that no specialist roofing or landscaping expertise is required. Wallbarn produced a layout plan for the customer to follow.

The size, shape, positioning of the extension and exposure to sunshine meant there was a risk of the roof becoming quite hot.

Due to the cooling properties of the M-Trays, with its deep substrate, the M-Trays® were the ideal solution.

The extension itself had been completed so no scaffolding or hoist was available to transport materials to the rooftop, the highly portable M-Tray® modules could be hand-carried through the house and passed out through a first-floor window.

Wallbarn’s recycled geotextile provides an added layer of protection between the trays and the waterproof membrane.

Their aluminium edging is also easy to cut and clip together, providing a neat border around the sedum roof.

Riverstone pebbles were supplied in 25kg bags, to provide a necessary and yet aesthetically pleasing break between the vegetation and the skylights on the roof.

The installation of all 131 units was completed in one day by two men.
