Interlocking Pre-Grown Trays

Roofscape® Pre-Grown Trays are easy-to-install, interlocking tray modules that have been pre-grown with plants (most commonly sedum) for use in extensive and semi-intensive vegetative roof profiles.

Roofscape® Pre-Grown Tray System provides a turnkey solution that meets or exceeds all guidelines for Green Roofs. The trays are easy to install and feature interlocking edges which prevent shifting or migration of growing media onto the roof membrane. At 24” x 24” x 4.625” deep, the pre-grown tray is appropriate for extensive and semi-intensive vegetative roof profiles. The modules are pre-grown with plants (most commonly sedum) selected by the project designer and shipped to the job site with approximately 90% or more vegetation coverage.


Comprised of a heavy-duty recycled polypropylene, the Roofscape® Pre-Grown Tray is designed with a channelized bottom to maximize stormwater retention. It can reduce both the amount and rate of stormwater run-off and is capable of retaining up to 70% of annual precipitation. Detailed stormwater retention calculations and hydrographs are available upon request.



Plants are grown per the project specifications, provided they are appropriate for the local climate zone and sufficient lead time has been provided. Please contact Barrett for more information.
