Project Overview
Founded in Vorarlberg in 1985, Baumschlager Eberle Architects has grown into an internationally active practice with offices across Europe and Asia. In 2016, the St. Gallen office moved into a new workplace building reflecting the city’s historic tradition of globally renowned embroidery craftsmanship. The interior design references this heritage through traditional St. Gallen embroidery integrated between glass layers along the façade, connecting local cultural identity with contemporary architectural design.

Acoustic Challenge
Extensive glazing and open office spaces required acoustic solutions that improve comfort and speech clarity while preserving transparency and the delicate visual character of the embroidered glass walls. Acoustic Solution Along the window façades and glass walls, the transparent acoustic curtain STREAMER pro (αw 0.8) was installed as a highly efficient sound-absorbing element. The translucent textile allows natural daylight to flow into the workspace while enhancing acoustic performance and maintaining visual openness. The acoustic curtain creates a subtle dialogue between function and tradition, complementing the ornamental glass surfaces without visually dominating them.

Application

• transparent acoustic curtain STREAMER pro
• sound absorption coefficient αw 0.8
• installation along glazed façades and glass walls
• preservation of daylight and transparency
• improved speech intelligibility in office environments
• integration with architectural and cultural design concept

Architectural Impact
The project demonstrates how textile acoustic solutions can bridge tradition and contemporary architecture, combining cultural identity with functional performance in modern workplace environments.

Textile acoustic solutions by Annette Douglas Textiles improve room acoustics, are flame-retardant, and preserve architectural transparency and design intent.
