Franz Safford, an architectural engineer, invented the VS-1 system in 2005 and was patented in 2015.
It was a response to what Franz observed as a profound need to improve building envelope performance and better
meeting the demands of architectural aesthetics and creative variation of the basic curtain wall.
Standard 70-year-old curtain wall technology remains largely unchanged and demonstrably unable to respond readily to the modern visions of architects and their clients. Franz saw the opportunity to evolve the technology and better meet these new demands with a new system.
Franz took a significant step forward by combining his knowledge of lattice structure (space frames), integrated wall systems, tension structures and all-glass assemblies using glass as the primary structural load-bearing system. It broke through the stagnant, stale concepts of the 1950s that have stunted innovation in curtain wall design.
No longer are curtain wall design details and performance attributes too expensive and unrealistic for large façade applications. This breakthrough enables designers to enact a level of detail that was previously too expensive or too complex. In its short history, VS-1 has already achieved that goal and begun to transform the curtain wall industry at exceptional value to the building owners.
