The Newest GreenGrid® Modular Vegetative Green Roof System The 5th Generation GreenGrid® Module Launches 2021 These new zero-edged modules are an imporvement to the previous generation of GreenGrid®, maintaing the functionality of the original modular green roof system, but adding improved structural design, multiple depth configurations, connectivity, and excellent stormwater retention. Unlike hybrid /subterranean modular systems and traditional layered systems, G5 modules can be easily accessed and removed to perform maintenance or repairs to the underlying roof without damaging the vegetation. Additionally, G5 modules are specifically designed to maximize stormwater control, and now allow irrigation lines directly beneath modules. GreenGrid offers versatility and design flexibility, with modules available in FOUR different depths for a variety of planting options. Modules can be pre-grown at our nurseries to meet plant coverage specifications up to 95% and delivered to the job site to create an instant mature green roof. This translates to a successful green roof with less up-front maintenance, plus a beautiful look from day one. In addition, GreenGrid modules can be custom cut with curves or angles. www.GreenGridRoofs.com GreenGrid is a registered trademark of Weston Solutions, Inc. (WESTON).
