Are the windows at the airports UV protecting? If it depends, how can I know?

I'm asking as one sometime wait under the sun for a prolonged period of time waiting for the plane to board.

    Most airports have tinted glass but how much UV protection it affords would vary from airport to airport, as I don't think there are any global legal standards for that. Personally I just avoid sitting in chairs that the sun is shining on. – user13044 Sep 8 '17 at 3:16
  • @Tom That's probably the best policy :-) – TheGrouch HK Sep 8 '17 at 4:35

As far as I know, glass is opaque for UV (partially opaque for near-ultraviolet) and plastic is even more so. This probably means that most of UV is blocked even without any special treatment.

  • Thanks. Are airport windows made of glass, plastic, or something else? – Franck Dernoncourt Sep 10 '17 at 8:06
  • @FranckDernoncourt I think that depends on which airport. – alamar Sep 10 '17 at 15:40
