Green Roof Isolation Cage

Isolation boxes for green roof applications. Made from stainless steel or aluminium in any size to suit the project.

On a Green Roof the outlets must be isolated from the growing media. This can be achieved with a layer of drainage mat against the isolation cage, and two layers of filter cloth placed against the drainage mat to further prevent fines from entering the drainage system.
