Carlisle SynTec, the leading manufacturer of single-ply roofing systems, continues to offer innovative roofing solutions with its new, GreenGrid Roof Garden System. Consisting of pre-planted, modular trays, Carlisle's GreenGrid Roof Garden System is a simple, fast and cost-effective way to install beautiful, environmentally friendly roof gardens. GreenGrid Roof Garden Systems are approximately half the cost of a traditional roof garden installation, saving building owners money and increasing profits for roofing contractors. The modular trays are lightweight and easy to handle, allowing roofing contractors to install the entire roof garden system without the need for landscape architects, further increasing profits. Carlisle's GreenGrid offers all of the benefits of a traditional roof garden such as aiding in storm water management and air purification. Roof gardens have also been proven to lower a building's heating and cooling costs while decreasing the urban heat-island effect in metropolitan areas that feature an excessive amount of concrete and pavement. The GreenGrid System comes standard with four-inch deep trays available in 2' x 2', 2' x 4', 2' x 2' triangles and 40" by 40" sizes that support sedum and other plants. The trays are delivered directly to the jobsite and can be installed over Carlisle's time-tested EPDM or TPO membranes. Eight-inch deep trays are also available in the 2' x 4' size.
