Nanoparticle Technology
Ceramic, not metal, is what does the work here. Kepler builds its ceramic infrared films to take out the infrared heat that turns a parked car into an oven: up to 98% of it on IR+, and 81% on IR.
What the Figures Mean on a Wisconsin Car
Three numbers get quoted and they measure different things. Visible light transmission is how much light comes through the glass, and it is the one Wisconsin regulates. Infrared rejection covers only the part of the spectrum you feel as heat, and total solar energy rejection is the broad figure. The limit applies to your glass and the film together, so ask your dealer to check the combination on your car.
