Württemberg State Library

Coexistence of communication and concentration made possible

In 2011, the architectural office LRO from Stuttgart won the competition for the extension of the Württemberg State Library. The extension building, which is located opposite the New Palace on the important Konrad-Adenauer-Strasse, together with the reading room of the old building and the neighbouring State Archives define a forecourt.

Württemberg State Library │ feco system partition walls │ system walls are acoustically decoupled

With handcrafted formwork of rough-sawn boards, the high quality of the exposed concrete is continued in the extension building as a reference to the old building. For the system partition walls, feco-feederle was chosen as the most cost-effective supplier. The corridor walls of the offices on the 1st floor and parts of the ground floor meet the architects’ high design standards. Continuous skylight strips with the frameless, flush fecostruct glazing with all-round 20-mm-thin edge bonding transport daylight into the corridor zones. The solid wall and door leaf surfaces have a white finish. The fecotür H70 with R_w,P = 37 dB and visually identical H85 with R_w,P = 42 dB corridor doors have concealed frames and flush door leaves on the corridor side. The flush, lacquered wooden skirting boards are visibly screwed on.

By mounting the feco system partition walls on pre-assembled sleeper timbers, the system walls are acoustically decoupled. Together with the high sound insulation test value of the fecowand solid wall of R_w,P = 52 dB with a wall thickness of just 105 mm, excellent sound insulation of the offices is achieved and the coexistence of communication and concentration made possible.
