Pregrown Modular System • Firestone Building Products

Firestone Building Products offers a new SkyScape^™ Pregrown Modular System as part of its SkyScape Vegetative Roof System Portfolio. The system’s unique engineered design manages rainwater 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.
