Air terminals are more commonly known as lightning rods. They are placed at intervals on the roof and on any high points projecting from the roof. Lightning rods are made of solid copper or aluminum and are drawn to a point. Their design and placement ensure that lightning will strike them and not another part of a building. Specifications for lightning rods vary depending on a roof`s type and size. Recommended height, anchoring methods, and spacing intervals can be found in the codes and standards previously listed. NYS
