Solar energy reaching your car arrives as visible light, ultraviolet and infrared. Infrared is the part you cannot see but certainly feel, and it is a significant share of the heat that builds up in a closed cabin. Kepler's nano-ceramic IR and IR+ films are built to work across that spectrum at the glass, which is why the shade of a film and its heat performance are published as separate measurements — one describes how dark the window looks, the other what the film does with solar energy. For a Tesla with generous glazing, that distinction matters: you can choose a look you are happy with and still compare films on measured performance. Check the data for the exact film and shade, and ask your installer how it applies to your model's glass.
