Sedum Cassette Trays, also known as Sedum Green Roof Trays, provide a complete, modular green roof system for creating instant extensive green roofs with no growing-in period. Each tray combines drainage, filtration, lightweight substrate, and pre-grown sedum vegetation into a single, ready-to-install cassette, making them one of the fastest and most reliable green roof solutions available.
Pre-grown with a diverse mix of at least eight drought-tolerant sedum species, these trays deliver immediate coverage, visual impact, and long-term resilience. The sedum plants are low-growing, hardy, and well suited to the exposed, low-nutrient conditions typical of rooftops.
Designed for quick installation, trays simply interlock and can be laid directly onto a prepared roof surface without specialist tools. This makes them ideal for new builds and retrofit projects, from small residential roofs and garden buildings to large commercial, industrial, and public sector developments.
Sedum Cassette Trays are widely specified by green roof contractors, landscapers, architects, developers, and local authorities, supporting Biodiversity Net Gain (BNG), SuDS, and urban greening objectives while delivering a clean, professional finish.
