Guardian Industries has introduced its first commercial low-E glass product with visible light transmission (VLT) above 50% and a solar heat gain coefficient below 0.25, in a standard insulated glass unit. The latest addition to the Guardian SunGuard portfolio of high performance, low-E glass, triple silver SunGuard SNX 51/23 has the highest visible light transmission in its class, low reflectivity and a neutral blue appearance. The glass is designed to meet the most stringent energy codes in North America without sacrificing appearance. SNX 51/23 is produced at Guardian's Dewitt, Iowa float glass plant. It is available on clear, green, UltraWhite, CrystalGray, grey and TwilightGreen substrates, in both annealed and heat treatable versions.
