Abstract
A cover assembly for an attic fan or the like permanently mounted in a wall or ceiling is provided which permits quick, easy covering of the fan opening when the fan is not in use during wintertime. The cover assembly is provided with heat insulation and a peripheral seal so that heat loss through the fan opening is minimized. In preferred forms, the cover assembly includes an insulated shell having a circumscribing lip which is adapted for face-to-face mounting adjacent the rim or flange of the fan assembly; a plurality of spring clips are employed for interconnecting the shell lip and fan rim for assuring a tight covering fit over the fan opening.
