Green Roofs for Healthy Cities (GRHC) products

The term green walls encompasses all forms of vegetated wall surfaces. However, there are three major system categories that fall under this term: green facades, living walls, and retaining living walls.

A green roof system is an extension of the existing roof which involves, at a minimum, high quality water-proofing, root repellent system, drainage system, filter cloth, a lightweight growing medium, and plants.
