Nanoparticle Technology
Nano-ceramic particles are built into the film to target infrared heat, the part of sunlight you feel rather than see. That is what allows a light film to work on cabin temperature.
Comparing car window films properly
When you are comparing films, look at the exact product and shade rather than the headline number. Visible light transmission tells you how much light passes through; it says nothing on its own about how the film handles infrared heat or ultraviolet light. Kepler publishes its ranges so you can line up the shade you like against the performance you need, and a dealer can talk you through the difference on your vehicle's glazing.
