A cooler car
Infrared is the heat you feel through the glass, on your arm and on the seats. Carbon IR blocks up to 75% of it and Ceramic IR up to 87%, so less heat builds up while the car sits in the sun.

Car window tintingWhy tint your car windows?
Blocks UV
Both films block 99.99% of UV, the rays that fade a dashboard, wear leather and reach your skin on every commute. That protection comes with every shade, so the lightest film still does the job.
Less glare
Low sun on the evening drive and bright headlights in the mirror both soften behind tint. Choose the depth to suit how you drive: darker on the glass behind you, lighter on the windows beside you.
More privacy
Darker glass behind the front doors keeps bags, car seats and tools out of view at every light and in every parking lot. From the outside, the cabin reads as clean black glass.
A factory finish
Each piece of film is cut for its own window and finished close to the edge, curved back glass included. The side profile looks deliberate and even, as if the car left the factory that way.
Stays black
Dyed film fades toward purple over time. Carbon IR is made with carbon particles, not dye, so it holds its color, and Ceramic IR is built on the same carbon base. Both stay black for years.
The filmTwo Union films, six shades, and what Texas allows
Window tint is a thin film installed on the inside of the glass. The shade sets how dark it looks; what the film is made of sets how much infrared heat it stops. Both Union films block 99.99% of UV, and the shades run from 5% to 70%.
In Texas, the front side windows need film and glass together to let through 25% or more of the light and reflect 25% or less. Behind the driver, any shade is yours, the back glass too when the car has a mirror on each side. The windshield takes a strip across the top.
- Both front side windows, at a legal shade
- Rear side windows, in any shade
- The back glass, shaped to its curve
- A windshield strip, if you’d like one
- Old film removed first, priced in your quote
- A final look over every window with you

Union shade viewerHow dark can you tint in Texas?
Darkest first. Tap a shade and watch the glass change.
35% · legal on the front doors
35% · Our most popular shade
Real privacy and one even shade front to back. Legal on the front doors in Texas, which ask for 25% or lighter.
Texas asks for at least 25% VLT on the windows either side of the driver, so the darker shades stay behind the front doors — rear glass can go as dark as you like.
Why choose usWhy Princeton drivers choose Obsidian Tint Co
- A set time for your car. Cars come in at a booked time, to a clean bay that’s ready for them. You know when to drop the car off and when it will be done.
- Tinted indoors. Every car is tinted inside, under bright overhead light and out of the wind and dust that spoil film. Good light shows every edge and every speck before the film goes down.
- Union film and warranty. As a Union Window Films dealer, we install Carbon IR and Ceramic IR, covered by Union’s limited lifetime warranty on qualifying installations for as long as you own the car.
- Your legal shade checked first. We check your front shade on your own glass before any film is cut, so film and glass together stay at 25% or more. You drive away legal, not guessing.
