{"product_id":"wallbarn-m-tray-modular-green-roof-system","title":"Wallbarn M-Tray Modular Green Roof System","description":"Create a lush, living roof in no time with the Wallbarn M-Tray® – a ready-to-go modular green roof solution designed for fast, clean, and beautiful installations. Each M-Tray® unit contains mature, UK-grown sedum plants set in a specially engineered substrate, allowing for an instant transformation of dull roof spaces into vibrant, eco-friendly habitats.\n\nThese lightweight trays are easy to carry and click neatly together, forming a seamless layer of established vegetation. No waiting around for plants to grow or blend—M-Trays® start looking like a continuous green carpet from day one.\n\nPerfect for both residential and commercial projects, M-Trays® are designed with 100mm deep planting cavities to support healthy root development, while smart drainage channels encourage strong, long-lasting growth. With no sharp edges or loose materials, installation is clean, safe, and low-impact on both the plants and your building.\n\nIdeal for tricky spaces such as single-storey extensions or commercial rooftops where traditional roll-out green roofs are difficult to manage, the modular format means the trays can be easily carried into position—even through narrow doorways or up stairwells. Need access to the roof deck later? No problem—simply lift individual trays without disturbing the rest of the roof.\n\n\u003ch3\u003eKey Benefits of the M-Tray® System:\u003c\/h3\u003e\nPre-planted with mature sedum for instant green coverage\n\nEasy-to-handle trays that simply click together\n\nGrown from seed at Wallbarn’s own nurseries in the UK\n\nSpecially formulated substrate promotes plant health and longevity\n\nDeep-root cavities (100mm) for strong, healthy growth\n\nIntegrated drainage system for improved plant resilience\n\nFire-rated to B ROOF (t4) with EXAP certification (CEN\/TS 16459:2019)\n\nNo mess, no sharp edges, and minimal disruption to your site\n\n\u003ch3\u003eFAQs – Wallbarn M-Tray® Modular Green Roof\u003c\/h3\u003e\n\u003ch4\u003eCan I walk on the M-Tray® green roof after installation?\u003c\/h4\u003e\nThe M-Tray® green roof is not designed for regular foot traffic. Occasional light access (for maintenance) is fine, but always walk carefully and use stepping boards if necessary to avoid damaging the vegetation.\n\n\u003ch4\u003eHow soon do the trays blend together visually?\u003c\/h4\u003e\nThe sedum plants are already well-established, so the trays start blending almost immediately after installation. Within a short time, the joins between trays become barely noticeable, forming a lush, continuous surface.\n\n\u003ch4\u003eWhat happens if I need access to the roof deck later on?\u003c\/h4\u003e\nOne of the key benefits of the M-Tray® system is flexibility. Individual trays can be lifted out and replaced without disturbing the rest of the roof, making maintenance and inspections quick and simple.\u003cbr\u003e\u003cp\u003eCheck out our full range of \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/roofing-supplies\"\u003eroofing supplies\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003eBrowse more \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/flat-roofing\"\u003eflat roofing\u003c\/a\u003e available online.\u003c\/p\u003e","brand":"Wallbarn","offers":[{"title":"Default Title","offer_id":50535987708246,"sku":"14374","price":24.76,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/4509\/4998\/files\/wallbarn-m-tray-modular-green-roof-system-9716892.jpg?v=1772662580","url":"https:\/\/jjbuildingmaterials.co.uk\/products\/wallbarn-m-tray-modular-green-roof-system","provider":"JJ Building Materials","version":"1.0","type":"link"}
