I believe Miroguard is being offered by supply vendors as an alternative to Tru Vue's glass for it's cost savings and a way around Tru Vue's very rigid purchasing agreements. I'm not sure of the difference in quality.

Mirogard from Schott AG and is a low iron, anti-reflective glass, with coatings that have been applied through a dip and bake system, as opposed to the ionic sputter coating that is used with Tru Vue or Luxar, from Glastrosche. All of these products have superb optical properties, but to get UV filtering one deeds the extra coating that Tru Vue can apply or to use another Schott product, Amiran TN, which is laminated,with UV filter in the laminate layer. Luxar Classic is the equivalent product from Glastrosche. These laminate products offer safety, UV protection, and great optics, but their price keeps them in limited distrubution.

Conservation Clear and Mirogard are not comparable products. Mirogard products are optically coated, but Conservation Clear is not. Mirogard would be more comparable to AR Glass (non-conservation) and Museum Glass (conservation).
According to the Schott Mirogard specifications attached, Schott Mirogard Plus would be similar to Tru Vue AR Glass.
Only Schott Mirogard Protect filters UV light comparable to Conservation Clear and Tru Vue Museum Glass. However, it is probably much more expensive than Tru-Vue's product, since it is laminated, almost twice as thick, and optically coated.

Thank you all. If I understood correctly Amiran TN would be the ultimate glass product if price was not important? The safety you have mentioned, is it shatterproof?

Which one of those products would be most suitable for conservation purposes? Do you know what museums use on more expensive works of art?

Museums use Amiran TN and Luxar Classic, when planar stability is of greatest importance. Optium has taken the place of these glazing materials, for many applications, but it is not a vapor barrier and can warp, when the relative humidity on one side is greater than relative humidity on the other.
