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.
Are there forces other than UV light that can contribute to damage to items on display?
Yes. While it is very important to reduce UV light exposure, this alone will not eliminate fading and other deterioration. All light, not just UV light can be damaging. Heat, pollution, moisture, the materials that make up the piece as well as poor quality framing materials are all contributing factors. Using conservation framing techniques and materials as well as properly displaying framed artwork will help minimize the risk of damage caused by these factors.
Is all UV filtering glazing 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 rays in the 300 to 380 nanometer range.
When should UV protection glass and acrylic be used?
Since UV light rays come from indoor and outdoor light sources, all items on display are vulnerable to the damaging effects of UV light exposure. That’s why it is important to use glazing with at least 97% UV protection on all of your custom framing projects.
Conservation framing materials and techniques should always be used on sentimental, valuable, limited edition and one-of-a-kind artwork. Also use UV protection glass or acrylic on all works of art your customers want to protect, especially posters and open edition prints. Posters or open edition prints are more susceptible to UV light damage since the inks, papers and other materials used to create them are more likely to deteriorate than those used in higher end reproductions.
