ABSTRACT:
A window insulating device is set forth wherein a first member telescopingly receives a second member in an interior surface of complementary configuration to the exterior surface of the second member. Each elongate member includes an inverted "J" shaped forward wall surface formed with an upper edge extending above and rearwardly of a rear edge side wall of each first and second member to provide a trough shape when the device is positioned adjacent a window and positioned upon an associated window sill. Cooled air is captured within the trough and heated prior to its ability to enter the room. To this extent, modifications include a mirrored internal surface of each of the first and second members to effect solar heating of the captured air, or alternatively may enclude a transparent envelope including a gel therewithin that is heated by solar rays and effects warming of the entrapped cold air.
