Nanoparticle Technology
Ceramic particles measured in nanometres sit inside a clear layer of the film, where they take on infrared energy before it reaches the cabin. No dye, no metal.
The Figures Kepler Publishes
Instead of one headline number, Kepler quotes infrared rejection, total solar energy rejection, ultraviolet transmittance and glare reduction for every shade. Total solar energy rejection runs from 66% to 51% across Kepler IR and from 72% to 51% across Kepler IR+. Always ask which shade a figure belongs to before you compare it against anything.
