Restoration glass provides performance and history
Bauhaus-University Weimar, Van de Velde Building
"The authentic restoration of the two buildings also called for recreating the appearance of the windows used at the time of construction. At the same time, we also put a lot of emphasis on glass functions that are consistent with the latest state-of-the-art technology."— Gerd Zimmermann, rector of the Bauhaus-Universität Weimar.
Bauhaus-Universität Weimar, Bauhaus.Atelier.
The basics: To celebrate the 150th anniversary of Bauhaus-Universität Weimar, Germany, officials had two of the university's historic buildings restored, the Van de Velde building and the Bauhaus.Atelier. Architects working on the buildings relied on restoration glass to create an authentic appearance while meeting requirements for security, performance, solar and UV protection. The Van de Velde building features restored window units, and the Bauhaus.Atelier a restored glass roof.
