Dear listers (please pardon the cross-posting), I would be interested to hear from the field about experiences (good and bad) with UV film and other methods of reducing UV levels through windows at historic house museums. Here at Drayton Hall, we are conducting paint consolidation and passive environmental management work as part of a larger conservation project, and we are having a hard time reconciling the benefits of UV film with the difficulty and expense of removing the film for replacement when the filtration degrades. For those who are not familiar with Drayton Hall, it was built 1738-1742 and is presented to the public unrestored and unfurnished. The paint in most rooms is only 7 generations thick (some spaces have only 1 or 2 generations). We wish to control the UV light in order to prolong the life of this fragile historic paint record, as well as to slow the process of degradation of other historic fabric. We are considering the reinstallation of interior louvered blinds (shutters from c. 1880) in selected spaces, but this will not be practical in much of the house. We, therefore, need a means to filter the light at the windows, either by installing film on the glass, film on roll-up shades, or some other method. Reversability is VERY important, as is low impact on the surrounding historic fabric, effectiveness of filtration, and the ability to continue operation of the window sash. Any comments would be appreciated. Our Web site at http://www.draytonhall.org has more information about the project and our site in general. Of particular note would be our Project Diary, which has a link on our home page.
