What about reducing the UV with window film then you don't have to worry
about the shades doing the job for you.  Check out Llumar films which
claim "Depending on the film selected, LLumar can cut from 12 to 93
percent of incoming light, eliminate 99% of the harmful ultraviolet
radiation
to protect fabrics and finishes, block 92% of glare and cut up to 76% of
solar heat gain through the glass."  The web address for US
architectural films is
http://www.llumar.com/na-eng/Architectural/building.html.  The plant is
in our town and the CEO has told me that they feel they block 100% of UV
but they don't claim it because it is possible to have tiny holes in the
film that render it 99%.  He said they sell quite a bit of it for people
who cannot be exposed to UV at all and have to have their windows
filmed, can only go out at night in the dark, etc.

Subject: Window Shades For A 1910 Structure

Our small cultural history museum is housed in a former Carnegie Library

building built in 1910. Sometime in the last 20 - 30 years someone 
replaced the original white shades with dark brown miniblinds. The
effect 
is to make the windows look like dark holes from the outside and hide
much 
of the beautiful original window framing on the inside. Although the 
entire building is in need of refurbishment (a project we hope to take
on 
in the near future in conjunction with the city who owns the building),
we 
think changing the miniblinds with white shades appropriate to the 
buiding's 1910 period of construction would go along way toward
improving 
the appearance and authenticity of the building.  
I am asking for help in my research for the appropriate shades. I would 
like to minimize the amount of harmful uv rays coming into the building 
while maximizing the light. Any references or sources as to all 
conservation considerations and vendors will be greatly appreciated. 
Thanks in advance.
