Copper is a chemical element (29 on the Periodic Table), and one of the most electrically conductive metals. It has probably been used by humans longer than any other metal. The word copper is derived from the name of Cyprus, where it was commonly mined in ancient times.
The material has a shiny reddish-brown color and weathers to a brilliant pale green. It is considered very attractive as a cladding for ornamental roofs, but is rarely used as a primary facade material.
The reddish metal can develop a green patina during weathering. Copper used as a facade surface is distinct from copper-colored paint or a different metal finished to resemble it.
