With framing that requires glazing we recommend using glazing with the ability to block the harmful UV light that is the biggest cause of fading and the deterioration of framed artwork. Museum glass blocks 98% of the UV and is coated to reduce reflections to the point that the glazing can almost disappear or look to be nonexistent. Conservation glass has the same clarity and reflections as regular glass, but with the ability to also block 98% of the UV. Both of these glazing options also come in acrylic forms when shatter resistance or, to some extent, weight is a factor in the framing decisions.
