Glass UV Transmittance is About 70%

You might think that since glass is colorless and transparent, letting through almost 100% of visible light (as it appears to us), it would also let through 100% of UV rays. However, UV rays actually get attenuated. This varies depending on conditions like thickness and surface state, but with ordinary glass, the transmittance is about 70% at a thickness of 5mm. For 12mm thick glass used in automatic doors, it's 50%. With laminated glass, it's almost 0% (meaning it can block almost all UV rays). I once saw an advertisement in a car catalog that said, "This car's window glass has a 99% UV cut rate!" I don't think they were lying, but it felt like a tactic similar to "unbleached XX (food)" – where they emphasize "unbleached!" even though "bleached XX" doesn't even exist, to differentiate from other companies' products. It's a way of advertising that isn't technically false but misleads consumers (when all other companies are doing the same without advertising it). In reality, are there cars that actually use window glass with less than a 99% or 100% UV cut rate?
