Turning Crystal Rainbows into Reality – Prismatic Glass Facades

By use of prismatic shaped glass, it is possible to transfer large scale vision glass areas into crystalized chandelier-like facades, turning natural sunlight into a fascinating optical interaction between façade responsiveness, cycle and solar altitude. Creating prismatic shapes on architectural glass can be achieved by different fabrication technologies. These are roll-forming of solid sheets, machine supported milling of glass surfaces and structurally laminating of prismatic glass elements onto a flat substrate. Each one of these techniques provides a different result in view of optical quality, safety and mechanical property. Based on three different case studies, the variety of technologies creating chandelier-like crystal prism-glass facades is being explained. The result is a design & engineering guideline usable for future approaches embedding deep textured and light-refracting glass into exterior architecture.
