2.3.2 Installations Cable supported green wall. Materials that are required in the installation of a cable supported green wall are:
Stainless steel hubs, 3mm dia. Stainless steel cable/wire, Wood screws and Plastic wire caps 1. Firstly, façade is marked as per the steel hubs distances. Equally divide the façade in grids.
