There have been some rumors about new materials that are embedded with UV "filters".  You may want to ask your fabricator for more info.

>Museum Colleagues:
>
>We plan to hang a large banner on the exterior of the museum, to draw
>people's attention to our building. This will be located on the east side of
>the building and will be 120" wide x 245" high.
>
>In the past, we have had such banners for traveling exhibitions. Lately, we
>have used ultraflex ultramesh for the banner, with no wind slits. This
>worked fine for the 3 - 6 months of the exhibition, and there was no
>substantial fading from the sun or wind problem.
>
>We now want to design a generic banner that can be up for long periods of
>time when we are not doing a traveling exhibition, e.g., for a year  or
>more. And, of course, we want the banner to withstand sun fading for as long
>as possible.
>
>I would much appreciate hearing from any of you who have experience with
>outdoor banner materials, and can advise on which materials will last the
>longest.
>
>Many thanks for your advice,
