See style and efficiency make a match

Choose SunGuard™ SN 68 coating on gray glass and redefine style and efficiency in your project. This double-silver solution on gray-tinted glass offers 34% visible light transmission, 6% outdoor reflectivity and 0.24 SHGC. Guardian gray glass achieves a pleasing color, excellent energy performance and enhanced privacy due to its low transparency compared to clear glass. This makes it a suitable choice for contemporary architectural designs.
