A window insulating attachment, including a translucent panel and ridges which form a chamber between the glass of the window and the panel. Air is withdrawn from the chamber through an air passage which is thereafter sealed. The partial vacuum in the chamber secures the insulating apparatus onto the window. The window and the translucent panel are spaced apart by the height of the ridges, forming an insulating layer of air, thereby reducing the transfer of energy through the window.
