Wallbarn M-Tray Sedum Wildflower Green Roof Module - 500 x 500 x 100mm

M-Tray® Wildflower: An Instant Modular Green Roof

The M-Tray® Wildflower roof system introduces an innovative solution designed to enhance urban rooftops with the beauty of nature. This system comprises specially-designed trays filled with a bespoke substrate mix and native wildflowers, creating an instant green roof that combines functionality with aesthetic appeal.

Each tray is designed for easy transport and clicks together seamlessly, forming a unified and verdant surface. Cultivated from seed at their own UK nurseries, the sedum and wildflower mix ensures mature vegetation of the highest quality. Tested to achieve a fire classification of B ROOF t(4) according to CEN/TS 1187 Test 4, the system prioritizes safety and reliability, underscored by multiple industry awards for its innovative design and effectiveness.

In addition to their sedum trays, Wallbarn offers a sedum/wildflower version of the M-Tray® for green roof systems. This variant supports urban greening initiatives by attracting diverse wildlife such as bees, butterflies, insects, and birds. By emulating natural fields on urban rooftops, the system contributes to environmental conservation efforts and habitat restoration.

The carefully curated mix of sedum and wildflowers ensures year-round green coverage and supports biodiversity. Selected for their low-growing nature, high succulence, and resilience in low-nutrient substrates, the native UK and northern European wildflowers enhance biodiversity and ecological balance.

Considerations for wildflower roofs include their potential for taller growth and periodic die-back, posing fire hazards compared to sedum roofs. While wildflowers may not offer the same consistent ground coverage or year-round greenery, their unique benefits include biodiversity enhancement and habitat restoration over time, with maintenance requirements tailored to ensure sustained performance.

The M-Tray® Green Roof stands out with its mature vegetation, click-together trays for seamless integration, and ease of transport and installation. The specially formulated substrate promotes plant longevity, with deep cavities ensuring healthy root systems and optimal drainage for robust plant growth. Designed without sharp edges or mess, the system minimizes disruption to plants, deck structure, and inhabitants.

Installed modules blend instantly to form a continuous green surface, ideal for transforming rooftops into vibrant green spaces. Access to underlying structures remains unimpeded, thanks to the modular design allowing trays to be lifted out as needed.

The system's simplicity makes it suitable for challenging installation scenarios in spaces like single-storey extensions, hotels, and commercial establishments. Modules measuring 500 x 500mm facilitate single-person handling and quicker installation compared to traditional methods, with convenient packaging ensuring ease of delivery and deployment.

The M-Tray® Wildflower system offers a turnkey solution to transform rooftops into thriving green environments, balancing beauty, functionality, and ecological benefits effortlessly.

FAQs about Green Roofs

What is a green roof?

Green roofing, also known as a living roof or biodiverse roof, integrates vegetation and substrate layers atop a waterproof membrane. This innovative roofing system serves multiple purposes: it absorbs rainwater, provides insulation, and creates a habitat for local wildlife. Green roofs are favoured for their eco-friendly benefits, combating urban heat islands, improving air quality, and extending roof lifespan.

What types of Green Roofs are there?

Green roofs are broadly classified into extensive and intensive types. Extensive roofs are shallow (80-200 mm), low-maintenance, and feature drought-tolerant plants like sedums. Intensive roofs are deeper (>200 mm), support a wider range of plants including shrubs and trees, and require more upkeep but offer greater design flexibility and recreational potential.

What options do I have for my extensive green roof?

For extensive green roof systems, you can choose between a Rollout System, involving multiple layers installed by professionals, or a Modular System. The Modular System consists of pre-grown interlocking crates, combining all necessary layers into a convenient package, suitable for various project sizes and complexities.

What are the advantages and disadvantages of each system?

Rollout systems offer cost-effectiveness for large projects and design flexibility but require professional installation and may pose challenges for maintenance and membrane access. Modular systems provide quick installation, easy maintenance access, and suitability for smaller projects. Choosing between them depends on project size, design complexity, and maintenance considerations.
