San Diego Highrise Uses Fire Rated Glass on South Facade

Because the Sapphire Towers' south facing elevation was in close proximity to the adjacent property, code regulations required the south façade to either be solid, which was contrary to the design, or to have openings with a minimum fire protection of 45 minutes. SAFTI FIRST® engineered a system that met the uniform design demands and performance requirements for the windows and balconies in all 32 floors in the south-facing elevation.
