Abstract
A heatshield and sunshield for placement within windows or windshields may be coiled within a permanently installed cylindrical container for storage. The container includes a spring in order to bias the shield in the retracted position. Tracks are installed for the upper and lower edges of the shield in order to maintain a precise distance between the shield and the glass. Preferably two storage containers are installed at opposite sides of the glass or window which the shields are to cover, in order that the shields may be extended from each container and joined to each other near the center of the glass or window. The shields are preferably coated with an aluminized or highly reflective coating on their outer surfaces and are preferably formed of a material of relatively high thermal insulating properties. In one embodiment, spacer blocks are used to position the tracks a precise distance from the surfaces to which they are attached in order to allow a positive circulation of air between shields and glass using the thermal siphon effect.
