[frameconnews] Glass and UV

[IMarsh5475@aol.com]

Wish regard to the general discussions on glass, two things.

Sue Maltby asks about UV filtering films. We have experimented with them, but 
found it impossible to apply them without getting small air bubbles trapped 
underneath This is no doubt down to our inexperience in application But the 
visual appearance was not pleasant. Since most customers will reject frames 
with even tiny faults this was obviously a non starter. laminated glass 
offers a good physical protection as well as UV filtering and is our 
preferred choice in these situations. We have however advised clients to a 
have these films applied to windows to protect contents inside their 
properties. There are specialist firms who can carry out this work. These 
films (like all UV filters) do have a lifespan and need to be checked on a 
regular basis.

We also have a uv monitor and periodically check filters but not every piece. 
I was interested in the posting from The fine Arts Consultancy on this matter 
and think it a sound policy that we will likely adopt. I would like to know 
what light source is used as a control, what the UV and lux output is, and 
wether there is an accepted  standard for this test source.
