Window Tint Film Types: Dyed vs Metallised vs Carbon vs Ceramic

Start with what a film is. A typical car film, such as 3M’s Color Stable series, is a polyester film with an acrylic adhesive on one side and an abrasion-resistant coating on the other. What sets the four types apart is what’s built into the film to darken it and deal with the sun’s heat: dye, metal, carbon or ceramic particles.

That difference decides how the film handles heat, whether it fades, how it looks from outside the car and what it costs. Here’s how they compare.

The four types at a glance

Type and shade are separate choices. Film lines come in several shades, from very dark to quite light: 3M’s Color Stable series, for example, comes in seven. Choose the type for how it performs and how long it lasts, then the shade for the look you want and the law in your state.

Dyed film

Dyed film darkens the glass with dye built into the polyester. It’s the budget-friendly choice, and it usually doesn’t reject as much heat as ceramic film.

Its weak point is age. Over time, lower-quality dyed films can fade, discolour or lose their original look. The purple tint you see on older cars is what happens when the dye that gives a film its black colour breaks down in the sun. Not every dyed film behaves that way: 3M describes its Color Stable series, a non-metallised dyed film, as colour stable, so it pays to check what a particular product promises rather than judging by type alone.

Metallised film

Metallised film uses metallic particles to reflect heat and sunlight, and it can perform well on heat. The trade-offs are its look and the metal itself. Metallised film tends to have a shinier, more reflective appearance than the other types, and some people worry about metal-based films interfering with electronics and signals, such as phones, GPS and radio.

Some metallised films can also lose their metal layer over time, which is why Solar Gard’s Australian warranty lists separate cover against demetallisation for some of its lines.

The shine matters legally too. Every state and territory limits how reflective window film can be, and some ban mirror-like film outright, so check the rules before you choose a highly reflective film.

Carbon film

Carbon film replaces the dye layer with carbon particles embedded in the film, and it sits in the middle of the range on price. It has an attractive, non-reflective finish, often described as matte black, helps reduce heat and glare, and has a more stable appearance than dyed film. Like dyed and ceramic film, it’s non-metallic, so it won’t interfere with GPS or phone signals.

Ceramic film

Ceramic film has tiny ceramic particles built into it. Because those particles are non-metallic, ceramic film avoids the concerns about metal-based films interfering with electronics and signals. It offers higher heat rejection than dyed film, long-lasting colour stability and a clean, non-reflective look.

The catch is cost: ceramic film may cost more than basic film options. For a customer, that buys comfort and longevity. For a beginner, it means every wasted piece costs more, which matters when you’re learning.

How to read a film’s spec sheet

Film makers publish performance figures for each shade, and the headings are similar across brands. 3M’s product bulletin for its Color Stable series is a typical example:

• Visible light transmission (VLT): how much visible light gets through. This is the number the law cares about, and lower means darker.
• Total solar energy rejected: how much of the sun’s energy, heat included, the film keeps out.
• Infrared rejection: how much of the sun’s infrared energy the film blocks.
• UV block: how much ultraviolet light the film stops.
• Glare reduction: how much the film cuts glare compared with the bare glass.

Two things stand out in 3M’s figures. Within the series, the darker shades reject more total solar energy than the lighter ones, while UV block is the same 99% across every shade. And each shade is measured on more than one kind of glass, with lower light transmission on lightly tinted car glass than on clear glass. The same film gives a different result on a different car, which is exactly why the legal limit is measured through the glass and the film together.

Warranties

Film makers back their car films with long warranties, but read the conditions. Solar Gard’s Australian warranty, for example, lists most of its car films with a lifetime warranty against defects such as adhesive failure, bubbling, cracking, delamination and peeling. It applies only to the registered owner of the car when the film was installed, ends when the car is sold, and doesn’t cover the installation itself. XPEL’s warranty for its PRIME car films, linked from its Australian site, covers defects such as discolouration, fading, bubbling, peeling, cracking and delamination for the life of the vehicle. It applies only to film professionally installed the way XPEL recommends, and it passes to a new owner only with proof of the original installation date.

In Australia, you also have rights under the Australian Consumer Law that a manufacturer’s warranty can’t take away. The practical point for a beginner is that warranties cover defects in the film, not mistakes in fitting it. Dust, creases and light gaps come from the fitting, and they’re on you.

Which film to practise on

Learn on film you can afford to waste. A piece with dust or a crease under it can’t be saved and has to be cut again, so you’ll use more film than the car needs while you learn. Cutting, shrinking and squeegeeing are the same basic skills whatever the film, so a budget dyed or carbon film is fine for practice.

Our guide on how to tint car windows covers patterning, heat shrinking and installing step by step, and works with any of the four types.

What Australian suppliers stock

You can buy all four types in Australia. A few examples from suppliers’ own websites, checked 12 October 2026:

• Solar Gard (Australian site): car film lines described as nano-ceramic, non-metallised and metallised, plus newer ceramic ranges.
• XPEL (Australian site): a range of car films that includes ceramic and dyed options.
• 3M (Australian site): the Crystalline series, a non-metallised film.
• Polyfilm Australia: an online supplier in Queensland selling film by the roll, including a carbon film infused with carbon particles and a ceramic film made with microscopic ceramic particles.

Prices vary a lot between brands, shades and roll sizes, so compare like with like. Our window tinting cost guide covers what film choice does to the price of a tint job.

The legal limit applies to glass and film together

Film type doesn’t change the law. The legal reading is the glass and the film together, and the glass in many new cars is made with a slight tint already, so a film that looks legal on its own can take the finished window below the limit.
