Nothing will fade vulnerable artwork faster than exposure to UV light. While direct sunlight is, obviously, the most common source, all light has some degree of ultraviolet light. We carry four products that are all effective at blocking up to 99% of all UV light, filtering it out before it can damage your art. Two are Conservation glass and acrylic Plexiglas. In addition, we carry TruVue's Museum Glass and Optimum Acrylic Plexiglas, which offer all the protection of Conservation glass, but also feature a non-reflective coating that provides a crystal clear, non-reflective medium that has to be seen to believe.
