In a one-inch insulating glass unit with clear glass, Graylite II glass has a solar heat-gain coefficient (SHGC) of 0.21, which is 36 percent greater than the original composition. It also retains the aesthetic appearance of the original glass, but has slightly lower visible light transmittance (VLT) of 8 percent.
Like its predecessor, which was launched in 1960, Graylite II glass is part of PPG’s Earth & Sky collection of nature-inspired tints. As a monolithic glass, Graylite II glass has a SHGC of 0.35 and VLT of 9 percent, which gives it the flexibility to satisfy a variety of glazing applications, including privacy glass.
Graylite II glass is available through members of the PPG CERTIFIED FABRICATOR (R) NETWORK and other qualified suppliers. To learn more, visit www.ppgideascapes.com or call 1-888-PPG-IDEA (774-4332).
