As one of four cultural institutions in the Catholic diocese of Würzburg, the “Museum am Dom” is an insider tip among culture lovers. Works of art from different centuries and styles, from Tilmann Riemenschneider, Johann Zink and Friedrich Karl Gotsch to Josef Beuys and Salvador Dali, can be found in the exhibition rooms. In order to create a visual connection with the museum forecourt, the museum management decided on a transparent solution and equipped the side facing the cathedral with a large glass facade. Seamless Protection The protection of the valuable exhibits, including lots of graphics were the focus of the structural work. This was particularly true when it came to UV protection. All exhibit pieces are additionally protected with special framing, which also protect from UV rays, but that was not nearly enough for those responsible: UV rays are known to have a strong bleaching effect on paper and textiles. Aggressive UV radiation leads to a gradual destruction of the precious pictures which are irreplaceable.  Therefore, the museum decided on the UV protection film type 2041 clear from Bruxsafol. UV filter additives in the adhesive system allow the film to reach an extremely high rejection level of UV radiation. The absorber formula is chosen so that the largest possible proportion of the UV-A spectrum – namely 99% (at 320 – 380 nanometers) – will be filtered out for many years.

Another significant advantage of the film is its visible light transmission of 90%. The crystal-clear film is absolutely transparent, so any color changes are not noticeable to the human eye. As a result, the museum rooms remain bright and translucent, making the exhibition appear spacious and open. In 2008, the “Clothing Physiological Institute Hohenstein e. V.” tested the film. It reached the maximum value for UV standard 801. In addition, the light fastness was tested and confirmed based on ISO 105-302.

“Flexible film systems offer architects, but also security managers, many options. Often easier to install and remove than glass, the products that are highly developed in solar technology provide an extremely high level of protection, not just in terms of solar and heat radiation,” explains Winfried Brux, Managing Director of Bruxsafol.

So for the Würzburg museum officials, film installation was the best way to sustainably preserve the unique works of art. It’s good to know that the films can be removed at any time, but it’s not worth mentioning. “We are glad that we have them,” says the museum management.
