Abstract
This invention relates to a wind door assembly for a doorway. The wind door assembly preferably has a pair of strip curtain wind doors each having cooperating edge stiffeners to prevent wind from curling the lower inboard regions of the doors out of the plane of the doorway when the doors are closed while allowing an object to move the doors apart from one another so that the object can pass through the doorway without damaging either the object or the doorway.
