A Tesla's windshield is large, and it is often where the most heat comes in, so owners ask about it regularly. Windshield film is regulated separately from side and rear glass, and the rules in Illinois govern what is permitted, so compliance has to be settled before a shade is chosen. Kepler IR+ is designed to deliver heat performance in lighter shades, which is what makes it relevant to windshield work where a dark film would not be appropriate. Ask your installer what is possible on your model and year.
