You might want to contact outdoor venues, like the National Park service, state parks, zoos, etc.  Not only do they have UV experience, but longevity in product.

>Hello-
>I'm wondering what materials folks are making indoor interpretive signs out of at your institutions?  Any thoughts on which materials resist UV best? 
>
>Currently we have a series of heavily faded signs that were originally printed on a hard black plastic that appears laminated to a clear acrylic/plexi front.  We're considering reprinting them (for a variety of reasons besides the fading), and due to the high amount of natural sunlight in our public spaces (and despite the 97% UV filtering windows) we're considering the option of doing more temporary signage this time around with the idea that we'll have to reprint them in another five years.  By more temporary, I mean drymounting UV-resistant content to something like gatorboard and mounting it under UV-resistant matte plexi.

>This would be significantly cheaper in the short run, but I'm willing to invest in something more longterm if it seems like it would work longer term, too...
