![]() ![]() ![]() Extensive mat systems can also incorporate larger plants with the BioBerm™ method. Trays, especially deeper ones (10–20 cm), can accommodate larger plants. It is more difficult with trays as they are either interlocked or “jammed” tight over time. Easy membrane access: mat systems, especially soilless, can be readily rolled back or cut for membrane access.These save as much as 25% labour on large roofs Glass glazed modular rooflights are available, incorporating the UPVC upstand. Mats and baselayers are flexible and much easier to cut than the hard trays. Intensive green roofs and roof gardens Extensive and non accessible green. Quicker installation: a typical mat is about 10X the size of a typical tray.Pre-vegetated mats are easy to cut and conform around drains, penetrations and curved and organic landscapes.Įasy to cut and conform: mat systems are easier and less messy to cut around drains and penetrations, they fit curved and organic landscape design without looking “pixelated” and conform well to 3D contours such as dome or wavy shaped rooftops Modular Pre-Vegetated Mat and Tray Systems Instant green, ease of installation, reduced establishment time and maintenance efforts are some attributes that make modular vegetated systems such as mats and trays popular in North America. Modular systems would be equivalent to laying sod. If we could use an analogy comparing establishing a green roof to starting a front lawn, built-in-place systems would be akin to sowing seeds. These pre-vegetated modules contain mature plants with 80+% vegetation coverage at delivery, and typically takes only one growing season to establish on the roof. These are called modular vegetated systems. Increasingly, vegetation is first pre-grown in modules on the ground for quicker establishment on the roof. Recovering natural spaces in cities with modular green roof. The initial vegetation coverage typically ranges 5-15% and it takes regular TLC (water, weed and feed) and patience (1-3 years) for the young plants to mature and establish. Development of modular green roof systems. Overall, the green roof retained 34 more precipitation than predicted by the paired watershed calibration equation. Where the purpose of this article is to set optimal solution for modular green roof panel which will be economical and environmentally friendly. These are called built-in-place vegetated systems. The green roof watershed retained 51.4 of precipitation during the study period based on area extrap-olation. Traditionally, vegetation has been established on roofs using plugs, cuttings or seeds.
