:::answer
Privacy glass is tinted during manufacture — the colour is in the glass itself. Window tint is a film applied to the inside of the pane. Privacy glass gives you the dark look; film is what adds meaningful heat and UV rejection.

## Why people tint over factory privacy glass

Privacy glass is usually around 25–30% light transmission, and its heat performance is modest. A quality film applied over it darkens the glass further and adds the infrared rejection the factory glass never had.

| | Factory privacy glass | Applied tint film |
|---|---|---|
| How it is made | Dye in the glass | Film on the inside face |
| Heat rejection | Modest | Good to excellent |
| UV rejection | Partial | Very high |
| Shade choice | Fixed by the manufacturer | 70% down to 5% |
| Matching front glass | Not possible | Legal-limit film available |

:::tip
If your car has privacy glass in the rear and clear front doors, a legal-limit film on the front evens out the look from the outside without touching the legal line.
:::

## Does film over privacy glass look too dark?

It can, and that is a real conversation to have before we cut. Over privacy glass we usually suggest 35% rather than 20% — the combined result lands close to where a 20% film would sit on clear glass.

:::key-facts
- Privacy glass alone does little for cabin heat
- Film over privacy glass compounds the darkness
- 35% film over privacy glass is the usual sweet spot
- Front glass rules are unchanged either way
