To meet all the design and code requirements, the architects selected fire-resistive, ASTM E-119 rated SuperLite II-XLB 120 by SAFTI FIRST® with Starphire Ultra-Clear glass for its superior optical clarity, large panel sizes and butt-glazing capabilities, which eliminated the need for obstructive vertical mullions for maximum transparency. With the largest individual glass panels over 10’ tall and over 4’ wide, this was easily accommodated by SuperLite II-XLB’s tested and listed size, which is the largest in the industry (133” maximum clear view height or width; 7,980 sq. in. maximum clear view area). As standard glass tends to have a slight blue-green tint from the iron-induced from the glass manufacturing process, low-iron Starphire Ultra-Clear glass was used for its superior clarity, improved color neutrality and high visible light transmission – all of which are integral to highlighting the vibrancy of Ortega’s artwork and transforming what would have been an ordinary stairwell into a significant element to this Starbucks’s immersive experience.
