I looked up typical coated window glass, and yes, it transmits some UV. You know that is the case because if it didn't transmit some UV, it would block some visible light and would have a prominent visible tint. So I think they all do, except maybe those strongly colored glasses on some office buildings.Most of it - it always depends , you would need to get the spectral transmission curves from the glass manufacturer.
EDIT: I was shocked to find out how much UV my windows pass. I thought I had a UV-free environment.
Just wondering if you have ever checked for fluorescence in ink (which could be unintentional). It might be subtle in appearance, but it could have an effect. The OBAs are subtle in appearance, but they have an effect. The ink on my calendar was certainly not intended to be fluorescent, but it is definitely not subtle.
