Apparatus and method of installation of a composite building panel

In combination,

• a building panel;
• a corrugated member adhered to said panel to form a back face of said panel, said corrugated member having an outside wall engaging face and an inside panel engaging face;
• anchor means integral with said corrugated member and extending longitudinally from an upper portion of said corrugated member;
• locking means integral with said corrugated member and extending longitudinally from a lower portion of said corrugated member;
• said locking means engageable with an anchor means of an adjacent panel having a corrugated member as a back face;
• and
• at least one elongated stiffener fastened to a surface of said corrugated member such that said stiffener extends within said panel.

A method of installing a plurality of composite building panels to a wall comprising the steps of:

• fastening at least one elongated stiffener to an inside surface of each of a plurality of corrugated members;
• adhering one of said corrugated members to each of said panels to form a back face of each of said panels such that said stiffener extends within said panel, said corrugated member having anchor means comprising a flange-receiving channel and locking means comprising a flange extending from an edge of said corrugated member;
• mounting a track means to said wall and mounting a first of said panels to said track means such that intermittent portions of said corrugated member adhered to said first of said panels are in contact with said wall;
• and
• presenting a second of said panels to said wall longitudinally adjacent said first panel such that said flange of said second panel engages within said flange-receiving channel of said first panel.
