Abstract: A building panel subject to interior condensation of moisture and exterior wind-driven moisture includes a sheet having an inner surface onto which condensed moisture forms. An open upper reservoir is positioned proximate a bottom portion of the inner surface of the sheet to receive the condensed moisture. A lower chamber having at least one drain port is positioned below the upper reservoir. A wicking port connects the upper reservoir to the lower chamber. The wicking port weeps the condensed moisture from the upper reservoir to the lower chamber to drain the upper reservoir. The condensed moisture drains from the lower chamber via the drain port. The wicking port blocks the upward flow of wind-driven moisture that enters the lower chamber via the drain port.
