Abstract: An apparatus and method for windlocking a curtain over an opening in a building is disclosed and claimed. The windlocking curtain can reside to the exterior or to the interior of the window, door or other opening and protects it from the intrusion of air, water or debris. In its upper position the windlocking curtain permits normal use of the opening and in its lower position it secures the opening. A flexible corrugated curtain has tension rods therethrough and the tension rods run in tracks on each side of the curtain and necessarily on each side of the opening. Interengagement of the tension rods with the tracks is accomplished by deformations in the rods that are referred to as interrupts. In one embodiment the rods are successively longer from top to bottom of the curtain and their interrupts matingly wedge with angled tracks to secure the curtain. In another embodiment the interrupts matingly engage parallel tracks upon the application of force due to wind, fluid (usually water or sea water) or debris.
