SunGuard® SN 51 Double Glaze on ExtraClear Glass (Europe)

Striking the perfect balance

Guardian SunGuard® SuperNeutral (SN) 51 is a new double-silver coated solar control glass with significantly reduced internal reflection. The introduction of SunGuard SN 51 is part of Guardian’s project to optimise its SunGuard SuperNeutral (SN) family of products in terms of their aesthetics and performance. SunGuard SN 51 is a high selectivity glass product with low solar factor and a slightly more neutral appearance than its predecessor, SunGuard SN 51/28.

The outside reflection has been set to an optimized level and provides a striking and vivid appearance of the glass. For exterior glass design projects in Europe, architects are moving towards glass solutions for facades that provide a more neutral appearance, giving a sophisticated, classy touch and look to the building. SunGuard SN 51 coated glass satisfies current architectural design trends by providing a highly desirable, consistent, neutral, transparent appearance – regardless of the viewing angle, combined with high light transmission and excellent thermal insulation, making it an ideal choice for both double- and triple-glazed windows and façades. SunGuard SN 51 is available in both annealed and tempered versions.
