American Hydrotech, a market leader in the development and distribution of premium waterproofing and roofing products and assemblies, recently announced the introduction of the InstaGreen® GT-4 pre-vegetated tray, an expansion of the InstaGreen® product line within the Garden Roof® portfolio of assemblies.

The GT-4 tray is one option for a stormwater management plan by providing valuable green space as a BMP on roofs to handle the first rains. It consolidates all growing media, drainage and vegetation in one convenient package for easy transport and installation by roofing professionals and landscape contractors. The tray is composed of 100 percent fully recycled content and features other key benefits such as: 

  • 12” x 24” high performance format can hold up to 4” of media for optimum plant growth
  • Unique reservoir base design for increased water capacity and sustained plant growth in times of drought
  • Perforated side walls to promote inter-tray root growth and water transfer
  • Integral connector clips to form a unified, seamless, vegetated surface and resist wind uplift forces.

Vegetation options for the InstaGreen GT-4 tray are a standard sedum species blend designed to accommodate the rooftop conditions. A range of perennials can also be added to provide increased color, texture and habitat features for the pre-vegetated roof.
