Method and apparatus for wall component drainage

摘要

A pan flashing including a pitched pan configured to wrap around a bottom of the door or window on three sides defining a bottom surface thereof; a plurality of spaced wedges extending from the pitched pan providing a weight bearing support for a sill disposed thereover; a front flange projecting perpendicularly and downwardly from a front edge defining a fourth side, the flange being fluted for fluid communication with channels defined by the plurality of spaced wedges, thus allowing ventilation up through the flutes to the pitched pan residing under the door or window and allowing a place for the water to flow out of the pan; and a front wall coplanar with the front flange and extending upwardly and downwardly from the pan, the front wall providing an attachment means for securing to a vertical stud framing the door or window, when installed.
