Vitro Architectural Glass

Affordable Low‑E, Low‑Iron Glass

The right glass can be the centerpiece of your design. Combining the color fidelity of new Acuity low‑iron glass with the performance you expect from the Solarban® family of glasses, you can design an ambitious façade—and actually realize it, on budget and on time. Acuity glass is available with the full range of Solarban® solar control, low‑e coatings.

Less Green. For Less Green.

Vitro market research indicates the installed cost of a glass and metal curtainwall averages $90 per square foot nationally. Upgrading a standard low‑e coated clear insulating glass unit (IGU) to Solarban® Acuity glass unit typically will increase the total installed curtainwall cost by only $1-2 per square foot.

Developed based on 30 years of Starphire® glass manufacturing know-how, using proprietary low‑iron materials and processes, Acuity glass is 60 percent less green than standard "clear" glass. For the ultimate in transparent low‑iron glass, Starphire® glass is 87 percent less green and also can be coated with Solarban® low‑e coatings.

Acuity™ low‑iron glass is specially engineered for vision glazings, both as a substrate for Solarban® low‑e coatings and for all lites in an insulated unit or laminated configuration. Because Acuity™ glass is designed for use in an IGU, it offers superior performance and optimal aesthetics for a wide range of façade projects. For configurations that require exposed edges, such as interior applications, Vitro recommends Starphire Ultra-Clear® low-iron glass for its signature azure blue edge and sparkling clarity.

All configurations include uncoated Acuity glass as the interior lite. Available coatings include:


In addition to office buildings, institutions, hotels and schools, Solarban® Acuity glass can be specified for exterior applications from luxury condominiums and mixed-use buildings to entrances and storefronts. Solarban® Acuity glass is also ideal for distinctive exterior applications such as atriums, skylights and spandrel glass.

Fabrication & Availability

Acuity glass is available in 6 mm, 8 mm and 10 mm thicknesses. Solarban® Acuity glass is stocked at all Vitro facilities for immediate shipment with the same lead time as all Solarban® glass products. All Solarban® solar control low‑e glasses are available through the Vitro Certified Network.

* Like Solarban® Starphire® glass, Solarban® Acuity glass delivers a distinctive low‑iron aesthetic with high transparency and visible light transmittance.
