PPG Industries has introduced OPTIGRAY® glass, an ultra-neutral, warm-light-gray glass designed to maximize light transmittance and clarity, and to work with SOLARBAN® coated, solar control, low-emissivity (low-e) glasses to enhance solar control performance.
Glenn T. Miner, PPG director of construction, flat glass, said Optigray glass is formulated to offer an extremely light-gray tint that eliminates the green naturally present in conventional clear glass formulations. The result, he adds, is “a highly transparent, super-neutral aesthetic that can actually show less color than clear glass.”
To optimize performance, Optigray glass is designed to function as a substrate for solar control, low-e coatings such as those on Solarban 60, Solarban 70XL, Solarban 67 and Solarban R100 glasses. In a standard 1-inch insulating glass unit (IGU), Solarban 60 Optigray glass has visible light transmittance (VLT) of 50 percent and a solar heat gain coefficient (SHGC) of 0.30, which yields a light-to-solar-gain (LSG) ratio of 1.67.
With Solarban 70XL glass in the same configuration, Optigray glass generates an LSG ratio of 1.99 based on VLT of 47 percent and a SHGC of 0.24.
Solar control, low-e, coated Optigray glass joins Solarban z50 glass and the recently announced Solarban z75 glass as the newest additions to a growing collection of high-performing, neutral coated glass from PPG. While coated Optigray glasses provide an extremely neutral warm-gray aesthetic, Solarban z-series glasses offer a cool-gray hue with a slight blue tint. All PPG neutral-coated glasses deliver excellent solar performance.
As part of PPG’s wide range of tinted float glasses, Optigray glass features an appearance that is considerably lighter and more subtle than that of SOLARGRAY® (light-gray) and GRAYLITE® II (rich dark-gray) glasses. Other tinted glasses from PPG are SOLARBRONZE®, SOLARBLUE®, PACIFICA®, ATLANTICA®, AZURIA® and SOLEXIA® glasses.
