Our gallery windows were coated with 3m Scotchtint film when the
facility was constructed in 1986. To date the product has performed
adequately (no apparent discoloration) though we have not tested its
efficiency for blocking UV recently (tests from about 4 yrs ago were
satisfactory). Because of glare from large or poorly placed windows
we have also installed polyester coated window shades, which have
been very successful. They are good-looking and provide greater
lighting control.

I would be interested to hear of any studies on longevity of various
window films/treatments.
