Vitro Architectural Glass (formerly PPG Glass) announced that it has launched Solarban R77 solar control, low-emissivity (low-e) glass, which unites a crisp, neutrally reflective silver-blue aesthetic with building-code-friendly solar performance.

The glass was designed by Vitro Glass to fill a specific niche in the company’s portfolio, offering architects a pleasant exterior-transmitted color that is more subtle than that of Solarban R100 glass, yet more pronounced than the quietly reflective appearance of Solarban 67 glass.

Nathan McKenna, director, marketing and innovation, Vitro Architectural Glass said Solarban R77 glass fulfills demand for a product that captures the visual character of the sky and ambient environment while enabling specifiers to meet increasingly stringent building code mandates.

“Architects are looking for a product that hits that sweet spot between transmitted color being too reflective and not reflective enough,” he explained. “Solarban R77 glass meets that challenge.”

Featuring a magnetron sputtered vacuum deposition (MSVD) coating, Solarban R77 glass delivers a solar heat gain coefficient (SHGC) of 0.25 in a clear 1-inch insulating glass unit (IGU). It also offers visible light transmittance (VLT) of 47% in the same configuration, providing clear exterior views and illuminating interiors with soft, natural, neutral daylighting. Exterior reflectance is just 25%.

Available through the Vitro Certified Network, Solarban R77 glass can be coated on conventional clear glass, Acuity low-iron glass, Starphire Ultra-Clear glass and Vitro Glass’s entire line of tinted glass. It must always be heat-treated, even for laminated applications commonly suited for annealed glass.
