I read on http://thespokaneshop.com/spokane-window-tinting/different-types-window-tint-film (mirror):

Ceramic film is also most effective in its blocking of ultraviolet light from the interior; in the case of ultraviolet light (the kind of light rays that contribute to sunburn and skin cancer), ceramic window-tinting film can block up to 99% from entering the interior.

However, the 3M official page on the 3M™ Automotive Window Film Color Stable Series (mirror) (made of carbon and not ceramic) also claims a 99% UV reduction:

Blocks up to 99% of ultraviolet (UV) light to provide a total Sun Protection Factor (SPF) of up to 1000 for you and your passengers.

Is ceramic window-tinting film the type of window-tinting film that is able to block the most percentage of UV radiations from entering the interior of a vehicle?

  • What are you skeptic about? That ceramic film can block "the most"? That claim is not made in the quotes. They both claim they can block UV radiation (and I don't see much reason to be skeptic of their claims, blocking UV is hardly rocket science). – DevSolar Feb 3 at 9:20
  • @DevSolar the first quote claims "Ceramic film is also most effective in its blocking of ultraviolet light": that's what I'm skeptical about. You think by "most" they meant "very" and didn't compare to the other types of tint? – Franck Dernoncourt Feb 3 at 9:21
  • That would indeed be my take. It is "most effective". Not "the most effective material, bar none". And as I said, blocking UV is rather easy. Even if you don't have the most effective material, you make the film a couple microns thicker. We're talking sunglasses-level technology here... – DevSolar Feb 3 at 9:36
  • It seems to me that the carbon window film might be the same/similar as the 3M product they are talking about. – JMac Feb 3 at 13:42

    Glass on its own is a pretty effective UV shield. – GordonM Feb 3 at 14:12
