Natural light, neutral color

Build bright, airy spaces, earn LEED® credits and reduce operating costs. With SunGuard SuperNeutral 68 coated glass, it’s all possible. This solution lets in high amounts of natural light while preventing the heat that usually comes with it. SuperNeutral 68 coated glass transmits the most light and has the most neutral appearance of any SunGuard solution. It can also be laminated to deliver sound reduction, security, safety and hurricane protection.
