Patent ID: 7562509

Claim:
A building panel subject to interior condensation of moisture and exterior wind-driven moisture, comprising: a sheet having an inner surface onto which condensed moisture forms; an open upper reservoir positioned proximate a bottom portion of the inner surface of the sheet to receive the condensed moisture, the upper reservoir having a floor; a lower chamber positioned immediately below the upper reservoir, the lower chamber and the upper reservoir separated by the floor of the upper reservoir, the floor of the upper reservoir bounding the lower chamber, the lower chamber having at least one drain port; a wicking port comprising an opening in the floor of the upper reservoir; and wicking material that substantially blocks the wicking port, the wicking material extending into the upper chamber and wicking the condensed moisture from the upper reservoir to the lower chamber to drain the upper reservoir, the condensed moisture draining from the lower chamber via the at least one drain port, the wicking material in the wicking port blocking the upward flow of wind-driven moisture that enters the lower chamber via the drain port.
