Construct a 2x4 frame across the area to be covered. Using nails or screws affix the first panel on the far right side of the frame. Install a panel on the far left side of the frame. Overlap panels by one corrugation and work toward center.
Typically it is just screwed to the wall. Either with normal screw and a pilot hole or with some self tapping screw depending on what it is behind attached to.
