Cable Facades – the flexible facade is the better facade Cable facades are, by far, the most filigree load-bearing constructions for building shells made of glass. They allow for maximum utilisation of light and solar energy, while exhibiting great stability in spite of being lightweight. Glass, point-holders (spiders), load-bearing cables and tensioning ropes form the primary components of a cable-supported facade. The pointholders are screwed together with glass panes, which are usually fitted at the glass pane interfaces. The special skill of facade engineers comes to bear in connecting tensioning and load-bearing cables made of stainless steel wires with spreader bars, both easily and in a forcefit manner. At the same time, load-bearing cables hold the weight of the glass, whereas tensioning cables provide the necessary pull to hold the facade in a stable position. Despite this, cable-supported facades are not rigid; compared to post-and-lock facades they have high levels of deformation and are flexible. However, this is not a sign of inadequate stability – on the contrary, due to their flexibility, facades with a stretched cable at the rear can be designed as explosionretardant, since they partially absorb the impact of an explosion. Additional arrangements have to be discussed from project to project.
