Who cares about the long-term preservation of art? This is SF where we worry about the hyphen in "anal retentive." I'm sure we could go on for pages about the advantages and disadvantages of various kinds of framing materials. We went on for 20 pages about Matt's toilet paper holder.
But you are probably right. Regular window glass blocks about 2/3 of UV light. Even if you frame with just regular glass you are blocking about 90% of the incoming UV.
But the museum glass thing gets really fiddly. You get to obsess about things like Krochman functions and whether the improved viewing angles from anti-reflective coatings are worth the possible increased damage from additional UVA transmission.
I feel this is just the sort of thing that could add meaning to SG's life, if only his homeowner's association would allow him to build small float glass bath in his back yard.
