SOLARBAN z75 solar control, low-emissivity glass, with a neutral, cool-gray tint and an exterior reflectance of 9 percent, enables it to harmonize with other building materials and other color-neutral, low-e glasses. In a standard 1-inch insulating glass unit, the glass has visible light transmittance of 48 percent and a solar heat gain coefficient of 0.24, resulting in a light-to-solar-gain ratio of 2.00.
