Nanoparticle Technology
Our ceramic IR films use nanoparticles to target infrared energy across the solar spectrum, so heat performance does not depend on how dark the film looks.
Setting the standard for car window tinting
Kepler's multi-layer ceramic construction is what drivers in Portage are really buying: managed solar heat, controlled glare and a clear view out, across a shade range from near-clear to very dark. Comparing the published specification of the exact film you are considering is the most reliable way to judge it.
