          A.FiberTite Green Multilayer: Patent-pending system includes a drainage layer, filter layer and retention layer, regionally-engineered growing media, specified firewise and firesafe plants, stainless steel or aluminum trim elements. The low profile multilayer system is designed to control flow of water and the drainage layer of the multilayer system is designed to keep the roof structure dry, while providing excellent airflow up through the system and while reducing wind uplift.
 
          B.FiberTite Green Tray System: Includes double interlocking trays, connectors, regionally-sourced engineered growing media, specified firewise and firesafe plants, stainless steel or aluminum edgers and integrated irrigation system. Growing media can be placed above level of interlocking trays for thicker beds because of interlocking design. Drainage system is designed to control flow of water and bottom of trays are designed to reduce wind uplift.
 
          C.Extensive Vegetated Roof Systems: Defined as low to no maintenance garden roof systems that incorporate a roofing and waterproofing membrane system that is covered with soil and vegetation in a growing medium that is less than 6 inches (152 mm) in depth. Extensive systems incorporate the following items within the assembly: deck and substrate, insulation, coverboard, roofing membrane, flashing membrane, sealant and adhesives, metal flashing, protection layer, drainage layer, filter fabric, water retention layer, growing medium, plants and vegetation.
 
          D.Growing Media: The engineered growth media and selection of appropriate vegetation is critical to the system's performance and must be properly engineered for each application. Seaman Corporation will arrange engineering for the vegetated system for a full-service, single-source system warranty.
 
          E.Phytroemediation: Use of green plants to extract pollutants, mineral elements, heavy metals, radioisotopes and other contaminants from soil and water environments.
