Sunlight is one of the most obvious threats to artwork, but it is far from the only source of harmful ultraviolet (UV) radiation. Everyday environmental exposure, including natural daylight entering through windows, can gradually affect pigments, paper, and textiles over time.
The effects are often subtle at first. Colours may slowly lose their vibrancy, whites can yellow, and delicate papers may become brittle after years of cumulative exposure. By the time these changes become noticeable, they are often irreversible.
This is where UV-filtering glazing plays an important role. Conservation-grade glass is designed to block a high percentage of ultraviolet light while still allowing the artwork to be viewed clearly. By reducing UV exposure, it helps preserve colours and materials for longer, particularly in works on paper, watercolours, photographs and limited-edition prints.
While no framing solution can eliminate every environmental risk, choosing glazing with strong UV protection is one of the most effective investments you can make in the long-term care of your artwork.
Display conditions also matter. Avoid hanging valuable pieces in direct sunlight or areas subject to excessive heat or moisture, and consider rotating sensitive works if they receive regular light exposure.
For collectors and artists alike, UV-protective glazing offers peace of mind that the artwork you enjoy today is more likely to retain its character for years to come.
If you're unsure which option is best for your artwork, the team at Artis Pura can help guide you through the choices.
