Nanoparticle Technology
Our ceramic IR window films use nano-ceramic particles to work on solar heat rather than relying on darkness alone, which is why even lighter shades can perform strongly.
Standards behind Kepler car window film
Kepler develops automotive film with a layered approach to solar heat, combining nano-ceramic materials with clarity through the glass. Compare the exact film and shade you are considering, since visible light transmission and solar heat performance are separate measures and a lighter film is not always the weaker choice.
