Framing: Museum Glass vs Art Glass, by nrgball on Sept 15, 2016 2:46:54 GMT 1, I was at my framer today and he offered me Artglass as an alternative to Museum glass. It's 1/3 the cost, has less reflection than Museum glass but only has 70% UV protection.
I wouldn't mind saving a few hundred bucks but will the art remain protected from UV light over the long haul. I could easily see this print staying in my life for 10-20 years. It's a Giclee by David Choe.
I'd love some thoughts from framers or those knowledgeable about the subject.

Framing: Museum Glass vs Art Glass, by iamzero on Sept 15, 2016 7:15:45 GMT 1, I have samples of Artglass and it claims 90%. UV protection. Slight green tint to it. Always been a trade off between this and Tru Vue con clear for me which has 99% uv protection. The amount of light protect offered has always won for me as the reflections I can live with.

^^^Agree with the above - go for optimum uv protection - the reflections won't damage your art, and as mentioned you can live with them.

Framing: Museum Glass vs Art Glass, by RoboJ on Sept 15, 2016 8:07:35 GMT 1, As above although I am surprised to hear of an Art Glass with only 70% uv protection. I think most are in the low 90%s. The museum glass tends to have a very high percentage uv protection (98%+) but it also tends to have better anti reflective properties too.

Framing: Museum Glass vs Art Glass, by agu on Sept 15, 2016 8:23:39 GMT 1, The % are minimal as it only refers to a portion of the spectrum that we cannot see. I.e uv. The entire spectrum contains energy that can cause fading but it would be silly to block visible wave lengths, as it would ruin the appreciation of the art.
UV accounts for 50% of light damage. Normal windows remove 57% of the UV already so 21.5% of the damage done to your art is UV the rest of the spectrum doing the remaining 88.5%.
So if you get 90% protection you prevent an additional 18% of damage 70% you prevent and additional 14%. So you only really gain 4% for your bucks. Over 20 years this might matter but far more important is the light source.
Contrast this to the source of light. Direct sunlight is 100,000 lux (lumens per Sq meter), full daylight is 10,000 lux. And overcast day 1000. Ambient lighting in the home is 150 lux (general /mood) to 500 lux (task lighting). Management of this will help across the entire spectrum not just the UV portion so.
So NEVER allow direct sunlight to fall on your pictures. No matter what glass you have it will destroy your art. After that any UV glass choice is fine (IMHO)... curtains, if you can bear them, work the best. Really valuable stuff interior or north facing rooms/walls .

Framing: Museum Glass vs Art Glass, by nrgball on Sept 15, 2016 14:50:41 GMT 1, Agu, thanks for the break down. I appreciate the info. What is your recommendation then? FYI, this piece will not be hung within range of direct. sunlight.
This particular art glass is 70% with better clarity than the museum glass and less reflection.

Framing: Museum Glass vs Art Glass, by nds on Sept 15, 2016 19:07:42 GMT 1, In fact I think the matter is even more confusing.
57% doesn't seem enough to me, bearing in mind by today's standards with sustainability requirements I think you'd be hard pushed to find a recent building that is below 69% transmittance double glazing 28mm split 6/16/6.
what gets me is 70% for a single pane and 95%+ for a single pane of museum glass, however a 28mm thick even with a coating on 1 pane can not achieve this. Maybe I am wrong in terms of the way I am understanding the G-value of glass. To be honest i'm curious as I have often gone for museum glass however I'm still unsure of it's protection apart from its visual clarity and the whopping great hit on my wallet.
