Clear

     Clear glass offers protection to your artwork from airborne particles (yes, there is dust even in your home!) and damage from small impact.  However, artwork framed with clear glass is still susceptible to fading from ultraviolet light.  Clear glass also reflects much of the light source, causing a distracting glare. This type of glass is ideal for non-valuable artwork, posters, and sometimes object framing.

Reflection Control

     Reflection Control glass, also known as "non-glare", is quite useful for subduing glare from the light source.   Glare is not completely eliminated, but rather is diffused to a soft glow.    Reflection Control glass has made vast improvements, even in the last few years.   This type of glass once had a reputation for image distortion, but that problem has been cut down drastically through an improved design.  Use this glass for non-valuable artwork that is displayed in areas with strong direct light.  While Reflection Control glass does block a percentage of UV light, valuable artwork should still be protected with Conservation glass.

Anti Reflection

     When it is imperative that your artwork be displayed without any distraction from glare, Anti Reflective glass is the best choice.   AR glass will make you want to reach out, just to see if there really is any glass between you and the 16th century tapestry you just had framed.  All but the very brightest and most direct reflection  is eliminated, so that your enjoyment of the artwork is completely unfettered.

Conservation

     Often, the most important consideration when choosing the glazing material is the longevity of the artwork.  Some inks and mediums are more susceptible to fading than others, and some artwork is completely irreplaceable.   Conservation glass blocks about 98% of damaging UV rays, protecting both the aesthetic and monetary value of the art. 

Acrylic

     Acrylic glazing, of which Plexiglas or Acrylite are examples, is used when weight or fragility is a concern.  Acrylic's light weight and resistance to impacts make it a wise choice for framing that is frequently exposed to flying objects (like any house with kids), framing that is moved often, or any unusually large framing project.  Acrylic glazing is also available with non-glare or conservation features.
