A shielding device for forward facing and / or windshield mounted / located sensors on an automobile protects sensors in close proximity to the windshield from temperature extremes associated with sunlight and extreme cold or wind. Modern automobiles tend to locate forward-focused collision avoidance sensors (sensors) around the perimeter of the windshield, typically at a central, uppermost portion. The windshield is subject to a substantial solar load, often emphasized by the angle of the windshield in direct sunlight. A reflective, insulating substrate disposed over the windshield mitigates extreme heat that can damage sensors in thermal communication with the windshield surface. The substate is affixed via the door seam, magnetic attachment, or engagement with the side mirrors or wipers.
