UV Protection for Slabbed Cards?

[BruceinGa]

This is from framedestination.com's website:
Frame Destination carries several types of UV-filtering glazing:

Artglass 99 UV-Filter, blocking 99% of UV light
Artglass AR92 Water White Anti-Reflective UV Glass, blocking 92% of UV light
UV Filter Acrylic, blocking 98% of UV rays
UV Filter/Non-Glare Acrylic, blocking 92% of UV light
Neither is “better” than the other, and the quality of the framing glass depends on many more factors than the mechanism of UV filtering, such as its clarity and any anti-reflective properties. The only surefire way to protect artwork from UV light is to store it in archival photo storage boxes and display a framed copy, as even glazing that filters 99% of UV light cannot completely stop degradation.

To best protect your possessions but still display your artwork, choose a suitable UV-filter glass and rotate out the pieces you display every few months, making sure that no paintings, prints and photographs are hanging in direct sunlight.
