Compare window tint

Pick up to three films and see how they stack up on heat, darkness and price. I'll also tell you when two numbers can't be compared fairly, because that happens more than the ads let on.

Darker isn't automatically cooler. A light ceramic film can block more heat than a dark, cheap one.

Rough comparison

These makers measured their films in different ways, with different glass, lab methods or slices of light. The numbers are a fair guide, but a few points either way doesn't mean one is better.

How each one was measured
  • ACrystalline CR BLK: 6 mm clear · ANSI/NFRC 200 · IRER 780–2500 nm; IRR 900–1000 nm film-only
  • BIRX: 6 mm clear · NFRC guidelines · IRER/SIRR 780–2500 nm
  • CXR PLUS: 3 mm glass · EN 410 · IRER 780–2500 nm; IR at 1025 nm

Heat blocked TSER

How much of the sun's total energy the film keeps out of the car. Higher means a cooler car.

  • ACrystalline CR BLK59%32% at the lightest shade
  • BIRX62%50% at the lightest shade
  • CXR PLUS71%52% at the lightest shade

XR PLUS publishes the highest number here, 71%. Measured differently, so treat a small lead as a tie.

Infrared blocked IRER

The part of sunlight you feel as heat on your skin. Higher is better.

  • ACrystalline CR BLK70%48% at the lightest shade
  • BIRX61%59% at the lightest shade
  • CXR PLUS70%67% at the lightest shade

Crystalline CR BLK and XR PLUS tie for the highest published number, 70%. Measured differently, so treat a small lead as a tie.

Shades you can get

The number is how much light gets through, so lower is darker. Check your state's legal limit before you choose.

  • ACrystalline CR BLK80%70%60%50%40%35%30%
  • BIRX50%40%35%30%25%15%5%
  • CXR PLUS70%55%45%35%30%20%15%5%

The number on the box

These are the big infrared figures in the ads. They're usually measured at one narrow slice of light, so they run high. Don't hold them up against the two numbers above.

  • ACrystalline CR BLK95–98% IRR
  • BIRX85–88% SIRR
  • CXR PLUS92–96% at 1025 nm

Ask your installer which of these they carry and why. A good shop will show you samples on real glass and tell you the legal limit in your state.
