Darkness and heat are two different things
How dark a film looks is its VLT, the share of visible light it lets through. How much cooler the cabin feels is infrared rejection, the part of sunlight you feel as heat on your arm. A film can be dark and still let the heat in.
| What you notice | Dyed film | ZV ceramic film |
|---|---|---|
| Heat | Does little for heat | 78.5% to 96.7% infrared rejection |
| Colour over time | Fades, often to purple | Lifetime warranty includes colour change |
| UV | Varies | 99.9% at every shade |
| Radio signal | No metal layer | ZV90 is fully metal-free |
The three ZV tiers
All three are in the ceramic family. They differ on construction and on how much heat they stop.
Questions
Is ceramic tint worth it?
If heat is the reason you are tinting, yes. Cheap tint is usually dyed film, which fades to purple and does little for heat. ZV90 rejects 96.7% of infrared.
Does ceramic tint look darker?
No. Darkness is the shade (VLT), and it is chosen separately. A light ceramic film can stop more heat than a dark dyed one.
Does tint interfere with phone or GPS signal?
ZV90 is fully metal-free, so it does not attenuate radio signals.
Will ceramic tint fade?
ZV automotive film carries a lifetime warranty that includes colour change.
Which tier should I pick?
ZV70 is the way into the range, ZV80 is the middle, and ZV90 is the one most customers choose. They differ on heat: 78.5%, 87.2% and 96.7% infrared rejection.
