Less solar heat in the cabin
Film works on the heat before it enters the car. With less solar energy passing through the glass, the interior warms up more slowly when the car is parked and settles down faster once you set off.
Whether your Tesla is used for daily commuting or weekends away, the glass does a lot of work. Kepler's nano-ceramic films are made to keep the cabin more comfortable through an Illinois summer while keeping the clean look of the car.




Kepler develops nano-ceramic automotive film in two ranges, IR and IR+, each offered in a set of shades. The shade you choose changes how much visible light passes through the glass; solar heat performance is a separate measure, so it pays to compare the exact film and shade rather than judging by darkness alone.

Plenty of owners arrange film in the first weeks of ownership, while the glass is still clean and unmarked. If a delivery date is approaching, it is worth sending your enquiry early so the dealer can talk through shades and book a slot that suits you.

Teslas carry a large area of glass, so on a hot Rockford afternoon the cabin can heat up quickly and the air conditioning has to work harder. Ceramic film reduces the solar heat reaching the interior, which can take some of that load off the climate system.

Nano-ceramic film also cuts glare and screens ultraviolet light, which is what fades and dries out trim and upholstery over time. In Illinois that matters in winter as well as summer, when low sun sits straight in the driver's eyeline.

Kepler's IR+ range is built around nano-ceramic technology aimed at infrared heat. Because heat performance and shade are measured separately, lighter IR+ options remain worth considering if you prefer a discreet look. Ask your dealer to compare the figures for the exact film and shade.
Kepler's ceramic film uses nano particles to target solar energy across the spectrum, with particular attention to infrared, the part of sunlight most responsible for the heat you feel through the glass.
Tesla glazing varies by model and year, from panoramic roof glass to large windshields and rear glass of different shapes. Identifying what is already fitted to your car is the first step, because it affects which film and shade make sense. A Kepler dealer can walk through the options with you and explain how each one behaves on your vehicle.

The film is a multi-layer construction rather than a single tinted sheet. Each layer has a job, from the ceramic layer that handles solar heat to the scratch-resistant coating that faces into the cabin, and together they give the film its performance and its finish.
Every Kepler film is published with its own performance figures, so you can see exactly what a shade does before you commit. Look at the numbers for the film you are considering, then decide how dark you want the car to look.
