Im at work and happened to walk by the loading dock and see a truck loaded with a bunch of office cubical partitions, I asked the guy loading them up what he was going to do with them, his reply was taken em to the dump So I immediately called the building authority and got permission to take what I wanted lol, so I loaded up my truck with about 4 - 5x5 panels, 2 5x3 panels, and 4 5x2 panels and a 3x5 panel with stabilizing feet. I have been mixing in a concrete box with no treatment so I am sure hanging these around the room will make a huge difference.
