As a follow on to @TwinTurbo’ reply, UV light, especially with a wavelength shorter than 250 nm, is almost nonexistent compare to visible and infrared light. The light emission spectrum for the Sun is shown below. The 220 nm wavelength mentioned above is about where the solar spectrum appears to touch zero. As expected, visible light has the greatest intensity and IR light is a bit less. There is no need to block the nearly nonexistent UV sunlight. Use a sunshade for your windows if you want to block UV from damaging your dashboard and fogging the inside of the windshield.
I mentioned this because there is enough UV light to break bonds in dashboard plastics and create gases that migrate to the windshield, but not enough to generate any significant heat compared to the balance of the sunlight.
