Hi, Folks-- Our Museum is housed in a 100 year old building, and our galleries are ringed with windows, which allow an unacceptable amount of heat, light, and attendant UV into the spaces. I am looking for some solution to mitigate the problem, other than masking the windows completely--we have no climate control, so it is necessary to open the windows on occasion, and *some* amount of natural light is not too obnoxious. Any of you out there had a similar problem, or can suggest a place to look? I've considered both UV plex sheathing and adhesive film for the windowpanes. . .any of you had experience with these? Specific brands or purveyors? Thanks in advance for any assistance! Dana Buck Kelsey Museum of Archaeology University of Michigan [log in to unmask]
