Described as an affordable complement to Vitro’s Starphire Ultra-Clear glass, the new Acuity low-iron glass offers a transparent, neutral and crisper view with a greater fidelity than regular clear glass. Compatible with Vitro’s suite of Solarban glazing, Acuity is also available in 6-mm. thickness for monolithic spandrel glass applications where true-color rendition is necessary, or to be paired with a low-E coated lite in an insulating glass unit.

The 55-story 181 Fremont high-rise features a distinct sawtooth patterned façade which dictates that window mullions in the curtainwall angle slightly in against one another, essentially functioning as a shading device. Vitro’s triple-silver-coated Solarban 70XL glass blocks 70% of the sun’s heat energy while enabling 65% of the ambient daylight to pass through.

NBBJ selected Vitro’s Solarban 60 and Starphire Ultra-Clear glass for their clarity and ability to facilitate photosynthesis. In fact, low-iron glass and a specific low-E coating—that allowed for 480 nanometers of light to come in while rejecting heat—was carefully chosen to promote plant growth for the more than 40,000 plants in the greenhouse.
