GRT3 Modular Green Roof Trays

A modular greenroof is made up of a series of trays, which hold engineered soil and plants. The greenroof can go directly on existing roofs, assuming necessary support exists, without retrofit and the associated costs. It provides the important elements associated with green roofs, including storm water retention, insulation, and membrance protection. Tournesol GRT3 green roof trays are made of extremely durable HDPE, with 60% recycled content. Unlike injection molded trays, the material resists cracking an splitting. They are available for either 4” extensive and 8” intensive applications. Raised drain holes at corners and along channels allow for 3/4” of storm water retention after rainfall.

How it works

Tournesol GRT3 Greenroof Trays

Tournesol Siteworks offers a simple, durable tray that can be used with any type of greenroof-type engineered soil in nearly any modular greenroof application. Modular trays are ideal for retro-fit applications, and small- to medium- size installations. Trays allow plants and soil to be shifted or moved from time to time, especially for roof maintenance or repair.
 
Tournesol Siteworks uses high density polyethylene to create a flangeless tray that will last the life of the project. The units feature a ½” storm water retention layer, and corner drain holes leading to 1” drain channels below. Use the 4” deep tray for extensive, the 8” for intensive greenroof applications.
