ABSTRACT:
An improved mechanism for the operation of multiple panels door with increased insulating properties comprises a means that keeps the door panels away from the seal as they move up or down vertically and that brings the panels tightly against the seal when the panels have completed their vertical course. In the prior art, a multiple panel door follows the path of the guide rail where in this instant invention, when the panels have run their course along the path of the guide rails, they are moved away from the guide rails and against the door frame, which results in the door panels to apply pressure against an insulating strip.
