Sustainable thin glass composite panels

Prof. Christian Louter, Daniel Pfarr, Silke Tasche The Institute of Building Construction is developing novel thin glass composite panels that are to be used as sustainable glazing. This is done by combining thin glass sheets with 3D printed cores that stiffen the panel. The 3D printed core enables a variety of structures that can be adapted to mechanical, physical or aesthetic requirements. An adhesive bond between the lightweight core structure and the flexible thin glass creates a rigid sandwich element for use as interior separation walls, façades and various other applications. The result is a lightweight and insulating glass panel for architecturally appealing glazing. Compared to traditional glazing, the novel thin glass composite reduces the use of raw materials and reduces the CO2 emissions related to its transport and installation. Also, by means of the 3D printed core, a sun shading effect is created thereby preventing overheating of the indoor environment and reducing cooling energy consumption.

Bauhaus Vision Sustainability: This project provides a sustainable glazing solution and targets for a reduced material use and reduced CO2 emissions compared to traditional glazing. Aesthetics: Compared to traditional glazing the 3D printed cores provide the opportunity to individualise the glass panels and to enhance the aesthetic quality of the panels.
