ABSTRACT
Traditional systems to co nnect glass t o the underl ying structure consist of linear supports. By using these systems the transparency of the facade i s highly reduced (Koch, 2 009). In contrast, the overall transparency improves significantly by using so-called point fixings. These fix ings typically consist of locally installed metal connecting elements of limited size. With this system glass facades can be constructed with hardly any visible fixing points. With the current state of technology it is common to make glass-metal point-fixings using bolts. More specifically, the latter requires the glass panel to be drilled near the corners or edges, tem pered and bolted. Th e bolts are then attached to the underlying structure, for example with cross-shaped anchors ("spiders").
