In Miami, a parked car can turn into an oven within minutes. Window tint is one of the most effective ways to take the edge off, and not only because it is darker.
Where the heat comes from
Sunlight reaching your car is made up of visible light, infrared and ultraviolet. Infrared is the main source of the heat you feel on your skin. UV fades the interior and is the part that harms skin. Visible light is what makes the glass bright and glary.
What tint film does
- It absorbs or reflects part of that energy before it reaches the cabin.
- Good films block nearly all UV, which protects your skin and slows fading of seats, dashboards and trim.
- It cuts glare, so driving into low sun is easier on your eyes.
- It adds privacy, since people cannot see in as easily.
Darker does not always mean cooler
The darkness of a film is measured as VLT (visible light transmission): the percentage of visible light that gets through. Heat rejection is a separate measure. A light ceramic film can reject more heat than a much darker dyed film, because it targets infrared specifically. Look for the film's total solar energy rejected (TSER) figure, not just the shade.
Choosing a shade
- Pick a shade that is legal for each window on your vehicle. Florida sets minimum light levels for different windows.
- Think about night driving. Very dark film on the rear windows is a common choice, but front windows should keep good visibility.
- Ask to see film samples in the sun, not only indoors.
Other benefits
A cooler cabin means the air conditioning works less hard, and getting into a car after it has been parked outside is less of a shock. Tinted glass also holds shattered glass together slightly better in some situations, though that is a side effect, not the reason to tint.
