The transparent-reflective Solarban R100 glass from PPG Industries adapts the same coating technology as Solarban 70XL glass. The solar-control, low-E glass delivers comparable solar performance with color-neutral, low exterior reflectance of 32%. Interior reflectance for Solarban R100 glass is 14% and it has a visible light transmittance of 42%. Its solar heat gain coefficient is 0.23, and its light to solar gain ratio is 1.79, which is 29% greater than comparable low-E glasses. It can be used in privacy glass applications and blends well with spandrels and other materials because of its neutral appearance. It also helps lower energy use for heating, cooling, and lighting.
