Vitro Architectural Glass

Just the Right Balance of Reflectivity

Solarban® R77 glass reveals new design possibilities with its neutral-reflective, soft silver-blue aesthetic.

Clear Views. Natural, Neutral Daylighting.

Utilizing a magnetron sputtered vacuum deposition (MSVD) solar control, low-emissivity (low-e) coating, Solarban® R77 glass joins Vitro Glass’s family of neutral-reflective low-e glasses to showcase reflectivity that is higher than that of Solarban® 67 glass but lower than that of Solarban® R100 glass.

Thanks to its balanced, reflective visual quality, Solarban® R77 glass is ideal for realizing façade and curtainwall designs intended to capture the visual character of the sky and ambient environment.

On the building exterior, Solarban® R77 glass offers a crisp, silver-blue transmitted color. On the building interior, Solarban® R77 glass provides clear exterior views and soft, natural, neutral daylighting. Its low interior reflectance means Solarban® R77 glass offers crisp, lively views of the outdoors.

Solarban® R77 glass must always be heat-treated, even for laminated applications commonly suited for annealed glass.

Building Code Friendly

Solarban® R77 glass allows specifiers to meet increasingly stringent building code mandates and satisfies performance requirements for all climate zones in the United States and Canada under ASHRAE 90.1 standards.
