A flexible device which can be detachably mounted on a window, such as a vehicle window, in order to prevent icing or fogging. The device is a semi-flexible sheet of layered materials having a length and width substantially coterminus with the window and having arranged at intervals along its two dimensions, holders which are used to detachably mount the device on the window. The sheet materials include a rather stiff supporting layer which acts as a backing surface of the sheet and a heat reflecting layer on the sheet side which faces the window when mounted. Optional layers include an insulating layer, a decorative layer, a silicone rubber electrically conductive layer and braided copper electrode strips for connecting the conductive layer to an electric source and causing the generation of heat from the conductive layer. The holders are of a length which will position the sheet a distance of about 5 to 15 mm away from the window. The air in the gap thus created is warmed by heat and light through the window. This process generates a connective warm air flow in the gap which prevents icing of fogging. |
