Solar energy reaching your Tesla's glass arrives as visible light, ultraviolet and infrared. Infrared is the invisible portion most responsible for the heat you feel on your arm through a window, and it is the part that dark, cheap film often handles poorly. Kepler's nano-ceramic layers are engineered to work on that infrared energy along with UV and glare, which is why a lighter Kepler shade can still be a serious heat film. Less solar heat entering the cabin means a more comfortable interior and less UV reaching seats, trim and screens. Because the numbers differ between ranges and between shades, compare the published data for the exact film you are considering, and remember that visible light transmission describes light passing through, not heat performance. An installer can look at your glazing and recommend what suits the car.
