Object: Scharfenstein Castle, Leinefelde Worbis - Germany

Execution: Floor, Acoustics and Wall paints


The Scharfenstein castle in Thuringia was equipped with new sound absorbers made of hemp

More than 800 year old walls, medieval flair and an impressive view of the Leinetal: The reconstructed Scharfenstein Castle in Thuringia has developed into a popular excursion destination in recent years. The historical property owned by the city of Leinefelde-Worbis has been extensively renovated and converted since 2006 and now offers visitors a café with a large panoramic terrace, guided tours, regular events and since autumn 2018, a "whiskey experience center": the "Number Nine Spirituosen Manufaktur LTD" demonstrates in the old walls of the core castle a show distillery the production of whiskey, offers tastings of various types and provides information about the many facets of the spirit.

Authentic lime paint

Since the castle is a listed building, special demands were made of the materials used during the renovation. The walls inside the core castle were to be given natural coatings - this requirement even applied to modern cultivation - an almost 20-meter-high tower that closes the former gap between the east and west wings. An authentic coat of paint was achieved with lime paint HISTOLITH.  This Paint is part of a special product series HISTOLITH from Caparol, for listed and historic buildings, is highly water vapor permeable, absorbent and can be painted over several times.

New generation of ecological sound absorbers

The other building materials should also meet the requirements of an interior design that blends harmoniously into the historic building. The "whiskey experience center" includes a vaulted cellar with a restaurant and bar, which is also used for tasting evenings and private events. Sound-absorbing measures were necessary to make this space usable and to provide entertainment there.CapaCoustic Nature is the name of the new generation of ecological sound absorbers from Caparol, which are made from the straw of the hemp plant. The commercial hemp is grown in Austria in regional agriculture without pesticides and synthetic fertilizers. The high degree of utilization of the hemp plant makes it a particularly efficient agricultural raw material. The hemp fibers obtained from the straw are pressed with the help of pressure and heat into a solid plate, similar to a fleece.

Visually appealing

"The effect is the same as with any other porous absorber," explains Caparol product manager Alexander Barchfeld: "The sound penetrates, is broken on the fibers and converted into heat." The panels can be glued flat on the wall or on the ceiling and recently also suspended from the ceiling as a ceiling sail. "The processing is pleasant," painter Lutz Engelmann reports, "the panels are dimensionally stable and can also be cut to size if necessary."

Scharfenstein Castle is one of the first objects in which the new hemp acoustic panels were used. "The main trigger was the look," says Burgpächter and whiskey world operator Bernd Ehbrecht. The robust surface was deliberately chosen so that the naturalness of the product is also visually visible. "The fact that it is a natural product makes things even more charming . "
