Nanoparticle Technology
Our ceramic IR films use nanoparticles to address infrared heat across the spectrum rather than relying on darkness alone, which is why lighter shades can still make a noticeable difference to comfort.
The standards behind Kepler car window film
Kepler's multi-layer ceramic films are chosen by drivers who care about how their car feels as much as how it looks. The construction is designed to manage solar heat and glare while keeping the glass optically clean, day and night, and to hold that performance over years of sun exposure. To compare films properly, look at the exact product and shade side by side rather than at darkness alone.
