Philly Green Wall has recently completed an extensive green roof at the Pleasant Playground Recreation Building in Philadelphia, PA. The extensive green roof is a pre grown mat system utilizing the GLTi mat system by Green Living Technologies Institute that provides superior water retention capacity, a seamless appearance with the roof accessible advantages of a tray system.
Philly Green Wall / g_space provides a waterproofing system that is as green as the vegetation that is installed on top.
In preparing for a green roof at the Pleasant Playground, Philly Green wall and roof installed a Hyload CTEM membrane waterproofing for the roof, adding tapered insulation to insure proper drainage, and a gypsum based decking board underlayment. The Hyload CTEM (Coal Tar Elastomeric Membrane) is a the 2 ply 150 mil thickness, is warrantied with ponding water, and is approved as a root barrier. The CTEM is made from recycled materials, manufactured in a process that does not produce toxic waste, and is low VOC.
The biggest advantage is that the Hyload CTEM and Philly Green Wall /GLTi provide a single source warranty for the vegetative material and roofing membrane, under our maintenance agreement.
