Abstract
A water resistant door assembly includes a door frame, a door hingedly mounted with the frame, and a threshold. The threshold has a height selected to be equal to or greater than a water head at a preselected design wind load pressure as a primary means to resist water intrusion. A series of gaskets, internal gutter troughs, and weep holes to the exterior of the door assembly provide a secondary means to resist water intrusion.
