The watertight patio door assembly includes two adjacent and laterally offset door panels mounted in a door frame, at least one of the door panels being slidably movable within the door frame. It also includes a combined air and water passageway located within a sill section of the door frame. The passageway provides a continual fluid communication between a location at a bottom end of a clearance gap, located between adjacent vertical frame members of the door panels when the patio door assembly is closed, and the exterior side of the patio door assembly. Two spaced-apart sets of weatherstrips create a vertically- extending buffer air space within the clearance gap. The disclosed arrangement can greatly improve watertightness between the door panels during severe weather conditions without the need of a complex arrangement and/or weatherstrips impairing the movement of the sliding door panel or panels. A method for improving watertightness between a sliding door panel and of a stationary door panel of a patio door assembly is also presented. |
