VLT explained: what 5%, 20%, 35% and 70% actually look like

Visible light transmission is the one number that decides how dark your windows look. Here is how to read it.

What VLT means

VLT stands for visible light transmission: the percentage of daylight that passes through the film. The lower the number, the darker the glass. A 5% film lets through one twentieth of the light; an 80% film is barely visible.

How each shade looks and feels

5% Often called limo tint. Full privacy in daylight; you cannot see into the car. Rear windows only.
20% Very dark from outside, still comfortable to see out of at night. A popular rear choice.
35% A clear tint that adds style and heat rejection while keeping a natural view.
50% Subtle. Most people notice the cooler cabin more than the colour.
70–80% Almost clear. Used on front side windows, where UK law requires at least 70% overall.

Darker is not the same as cooler

Heat rejection comes from the film's technology, not just its shade. Our Pro HD Nano Ceramic film rejects up to 99% of infrared heat at every shade, so even a light 70% front film makes a noticeable difference on a sunny drive.

A common setup

20% or 5% on the rear windows and screen, 75–80% on the front sides. Dark where it is allowed, cool everywhere.
