Approaching Curved Annealed Glass

Contemporary architectural designs of transparent building skins with curved geometries challenge the industry. Approaches using geometry rationalization in combination with planar glazing, cold bent glazing or warm bent curved glass are coupled with geometry constraints and not always architecturally desired. Warm bent annealed glass opens up additional freedom in design especially more and biaxial curvature in the building skin’s glazing.

The paper will provide an overview of the currently applied engineering approach applied in the industry for curved warm bent glass in the absence of standards and codes. Design specifics of warm bent annealed glass applications will be highlighted and test results shown. It is an experience report of how innovative annealed curved glass applications can be realized with the currently available knowledge of research projects, engineering tools and project specific testing.
