Firestone Building Products offers a SkyScape™ Pregrown Modular System as part of its SkyScape™ Vegetative Roof System Portfolio. The system’s unique engineered design manages stormwater through unitized moisture retention reservoirs and encourages airflow beneath the modules. That airflow passes through a 1.75-inch vertical space created by the reservoirs. Built on a foundation of a 100 percent recycled high-density polypropylene, the unit’s honeycomb design allows for moisture and nutrients to be shared between modules. For more information, visit
