The white panels are a 4 mm aluminum composite panel that comes in 4' x 8' sheets. We cut them on site to what ever pattern we are looking for and install them over a 1/2" furring strip to give it depth. They are secured with rivets heads and screws to give it an industrial look. They can be used inside and outside. These panels are called Oculus panels (http://www.oc-ww.com/) and come in different colors. We happen to be a local distributor of these in the Seattle area.

Thank you SO much for the reply. :-)
