A thermal insulating shade is made up of a plurality of panels, spaced apart and defining a serpentine air flow path between them. A blower connected to the air flow path ventilates the shade to augment its insulating effect. As least one of the panels has a highly reflective surface to reflect heat. The shade is reversible and removable and useful for insulating building windows and vehicle windows and windshields.

Thermal insulating shade to be placed adjacent to and substantially overlaying the interior surface of an area to be insulated, the exterior surface of said area being exposed to variable weather conditions including sun\s heat and winter\s cold, the thermal insulating shade being both reversible and removable and comprising: a plurality of panels, at least one of which has a highly reflective surface on one side thereof, said panels being shaped to conform in size and shape to the interior surface of the area to be insulated; means for supporting said panels in spaced, substantially parallel relationship to each other to provide air space therebetween; means for releasably mounting said plurality of panels in substantially parallel spaced relationship to the interior surface of the area to be insulated, so that one side of the thermal shade is insulated from the heat or cold prevailing on the other side thereof by reflection of said highly reflective surface, as well as by the insulating effect of said air space between said panels; and means for circulating air through said air space to increase the insulative effect of the thermal shade, said air space being divided into a path for the flow of air provided between said panels, said path being longer than the distance from one end to the other of said panels, said path being provided by attaching each of said panels to its adjacent panel in parallel spaced lines to form air passages therebetween in such a way that each of said spaced attachment lines are terminated short of alternately opposite edges of the thermal shade, leaving openings for the passage of air from one said air passage to the next at alternating edges of the thermal shade.
