54' facade · 19" VS1 mullion; largest unreinforced aluminum curtain wall in US
This project is our largest unreinforced aluminum curtain wall in the US at 54’, and is made possible by a 19”-deep VS1 aluminum mullion. This impressive clear span is achieved without any steel reinforcement or backing structure and will be a new world record for an unreinforced aluminum curtain wall. Only one splice plate is required for the entire 54’ assembly at mid span offering an incredible display of structural aluminum.
