Car, home and commercial window film in National City
Kepler makes advanced window films for vehicles, homes and commercial buildings. Depending on the film and the glass it is applied to, tint can cut glare, reduce solar heat and add daytime privacy in National City, California. Tell us about your project and a Kepler dealer will take it from there.

A window film for every project
Kepler builds ranges for very different jobs, from nano-ceramic automotive film to architectural film for glass at home and at work. The right choice depends on the glazing you already have and what you want the film to do.

Services from your Kepler dealer
Vehicles, homes, offices and storefronts all ask something different of window film. Start with the category that matches your glass, then compare the exact film and shade with your installer.
Tint law
California window tint law
California limits how dark each window can be, with the same limits for sedans and SUVs or vans. VLT is the share of light the glass must still let through: a lower number is a darker tint. Pick a shade inside the limit for each window and you stay legal.
| Window | Sedan | SUV / van |
|---|---|---|
| Windshield | Top 4 in., non-reflective | Top 4 in., non-reflective |
| Front side | 70% VLT or lighter | 70% VLT or lighter |
| Back side | Any darkness | Any darkness |
| Rear | Any darkness | Any darkness |
- Reflectivity: No metallic or mirrored
- Colours: No red, amber
- Medical exemption: Medical exemption available
- Compliance sticker: Required (installer)
Values are a general reference. Confirm with your state DMV before you tint — laws change, and enforcement varies. Checked September 2026.
