Innovations to GreenGrid Green Roof Take Stormwater Retention to a New Level
West Chester, PA., November 1, 2011 - Weston Solutions, Inc. (WESTON®) announces the launch of a new GreenGrid® green roof product. The company’s newest release, the G4, significantly improves the benefits the modular green roof system is already known for, including its simplicity of design, flexibility, aesthetic appeal, and stormwater retention capabilities.  The all new “G4” GreenGrid modules maximize stormwater capture by engineering a critical balance between high water retention and system weights. Heavy rainfalls produce higher flows and volumes of stormwater runoff that require storage, channeling, and in some cases, treatment. In many cities this causes excess water and contaminants to overtax sanitary and stormwater systems resulting in flooding and severe surface water impacts. Vegetated green roofs help mitigate those issues, but the G4 system takes it to a new level. It’s capable of mitigating up to 5,300 gallons of stormwater from a typical 1-inch rainfall on a 10,000-sq-ft GreenGrid installation—23% more than previous GreenGrid modules.
With a new zero-edge design, module edges are so thin the seams are nearly invisible beneath a mature pre-vegetated green roof. Fully mature and aesthetically beautiful upon installation, the new module will be sought after for both its visual and functional benefits. It not only expands a building’s useful space by creating dynamic and appealing healing gardens, vistas, patios, and rooftop entertainment areas, it improves energy efficiency and reduces the urban heat island effect. GreenGrid consists of 2-ft by 2-ft modular trays made of 100% recycled materials. Modules, offered in
4-, 6-, and 8-inch depths, are planted and maintained at a partner nursery, delivered pre-vegetated, and then placed directly on the waterproofing membrane of the building’s roof. Unlike layered-style and hybrid systems, GreenGrid modules remain completely modular, allowing easy access to a facility roof. Modules can be removed, set aside, and replaced if rooftop maintenance is needed. “We are pleased so many of our clients choose sustainable projects such as green roofs,” said Patrick G. McCann, WESTON’s president and chief executive officer. “As health care and university installations realize the benefits of green development, the new G4 module is just one more way we can help them achieve their sustainable, green goals, including contributing to Leadership in Energy and Environmental Design (LEED®) credits.” This year WESTON surpassed the 4 million-sq-ft mark of GreenGrid installations around the country—walking the talk by installing GreenGrid roofs on WESTON regional offices in Concord, NH, and Lakewood, CO.
