TRUEVUE: Glazing that enhances and protects
Is all UV filtering Glass the same?
No. There is a distinct difference between UV filtering glazing and glazing that provides UV protection. According to PPFA Guidelines for Framing Works of Art on Paper, for glazing to be labeled as providing UV protection, it must block at least 97% of the UV light rays in the 300 to 380 nanometer range.
Tru Vue® Conservation Grade glass and acrylic products are the only glass and acrylic products available in the industry that offer this level of protection. In providing at least 97% UV protection, Tru Vue Conservation Grade glass and acrylic products are considered "photo-safe" by meeting ISO 18902 and passing ISO 18902.
Is the UV coating permanent?
Yes. Tru Vue manufactures its Conservation Grade glass products by applying an inorganic silica-based UV inhibiting coating to the glass surface. The UV coating is “baked” into the glass, producing a permanently bonded coating. Tru Vue Conservation Grade glass products have been field tested for over 20 years and do not delaminate or degrade over time.
When should UV glass be used?
UV filtering glazing should always be used to frame artwork, since damge from UV light rays happens whenever your art is exposed to non-UV filtered light sources.
Why is UV protection important?
Without at least 97% UV protection framed pieces will age and fade more rapidly. Indoor and outdoor UV light rays contribute to severe color loss, paper embrittlement and deterioration of framed pieces. These effects are both cumulative and irreversible. The materials that make up the piece, the paper or fabric on which the image is displayed, may become brittle. Photos may appear yellow or stained with ghostly silver deposits rising to the surface. Once damage from light has occurred, it can never be reversed. That’s why it is important to understand what you can do to minimize this type of damage before it happens.
How does anti-reflective glass work?
How does anti-reflective glass reduce reflection?
The thin film coatings on Tru Vue anti-reflective glass disrupt the energy contained in light waves causing them to flow out of sync. This disrupted wave pattern virtually eliminates all reflection from the glass surface. Diagrams of how this process works are available from your framer.
