Abstract
Abstract An overhead door construction comprising a flexible door mounted on a spring loaded rotatable drum such that the door may be moved to open and close the opening. The door is constructed of panels having edges hingedly connected together, ends of the panels being locked together with keys and being slidable through a guide channel lined with sound deadening material. A resilient wind baffle is secured to the door, and has free edges to allow the central portion of the baffle to spring outward into sealing relation with the wall adjacent the top of the door. Wind locks prevent lateral deflection of the door.
