all created equal?

Maybe you're going to need to define "archival" in this context.

Are you asking if the coating will harm the artwork? (I'd say the answer is no.)

Or are you wondering if it will prevent fading? (Again, no, but it will slow it down.)

Or maybe you're wondering if the UV filtering will diminish with time? (Despite rumors to the contrary, I believe the answer is, once again, no.)

Ron,
Is this realy an urban myth? I have ALWAYS been told that UV filtering products will diminish in their effectiveness over time. Is this a widely held belief that everyone has been keeping from me for all these years?

UV coatings that are sprayed on photos & such will degrade over time. Perhaps that is where you got your information.

The UV coating on glass is an entirely different kind of product, and it will not degrade over time. An alloy is actually fused to the glass; it is quite permanent, according to all of the manufacturers who use that technology.

Ah.

You could ask to see the spec sheet from the manufacturer and you could compare them with the specs on Tru Vues website.

You could post the name of the company you're considering and ask if anyone here has had any experience with them (keeping in mind that such narratives are not going to be as objective as the technical specs.)

Tru Vue is by no means the biggest company that sells UV-filtering glass, though they have arguably done the best job of marketing to framers (and thereby appearing to be the biggest.)

For what it's worth, I use the Tru Vue products, but would never dismiss a competing product if:

</font>
  • Its specs were as good or better</font>
  • I could get delivery, preferably from a company I was already buying matboard and/or moulding from</font>
  • It was intelligently packaged and consistently arrived in good shape</font>
  • It looked at least as good as Tru Vue CC. I don't object to the slight orangepeel rippling, but I won't tolerate an obvious color cast or frequent flaws.</font>
 
When I was still living in Calgary, AB, I had purchased a 32x40 case of Artist Choice UV clear glass from my supplier in Edmonton (before they started carrying Tru Vue). When I finally got around to using some of it here in N.S., I discovered that a lot of the glass has small pits in it and it is unusable. I won't be purchasing that brand again and I find the Tru Vue conservation clear much better to work with.
 
Tru Vex is a manufacturer of curved and convex glass. They may be distributing someones else's UV coated glass or, I suppose, it's possible they are coating someone else's glass.

Find out how it's packaged: paper interleaving between lites, blue film on each lite, or whatever. That might give a clue about where it really comes from.
 
Also, check on the delivery of glass by the company. I am in the Fingerlakes, and it was almost impossible to get glass for framing delivered. I have one local distributor that delivers and they sell Tru Vue.
