Guardian Glass Europe Launches a Double-Silver Coated Solar Control Glass with a Neutral Grey Appearance and Enhanced Performance

Bertrange, Luxembourg, September 05, 2018 – Guardian Glass has introduced a new double-silver coated solar control glass with a grey, neutral appearance that meets current architectural trends for glass facades and windows.

Guardian SunGuard® SuperNeutral™ (SN) 63 not only satisfies current architectural design trends, but also offers a range of performance enhancements, including:

  • high light transmission (63% in double insulating glass unit (IGU)* and 56% in triple IGU*)
  • excellent thermal insulation (Ug value = 1.0 W/M2K in double IGU and 0.5 W/M2K in triple IGU)
  • excellent solar control (33% in double IGU and 30% in triple IGU).
  • very low external reflection (12% in double IGU and 14% in triple IGU)
  • neutral and low internal reflection (16% in double IGU and 19% in triple IGU).

These performance attributes make SunGuard SN 63 an ideal choice for double- and triple-glazed windows and façades.

Nicolas Gouzou, Product Manager at Guardian Glass Europe comments: “In interior design projects, the colour grey has long since shaken off its image of being gloomy and depressing. Homes, offices and public buildings are now being decorated with fashionable grey, a colour that is extremely versatile. Exterior glass design projects in Europe are following this same trend. Architects are moving away from glazed facades with a greenish tint appearance towards glass solutions that provide a neutral grey appearance, giving a more sophisticated, classy touch and look to the building.

”With input from the design and architectural community, Guardian Glass developed the product specifically to meet this growing trend.

“In addition to its appearance, we’ve also enhanced its performance to provide anexceptional combination of benefits, allowing architects to precisely tune the building envelope to suit the environment, the climate and to provide optimal comfort for building occupants,” adds Gouzou.

SunGuard SN 63 is available in both annealed and tempered versions.

Guardian Glass is continuously developing and refining its SunGuard range of coated solar control glass products to more closely meet and exceed the demands of architects and designers.

Guardian Glass will showcase SunGuard SN63 at glasstec - HALL 10 | STANDA24 (23-26 October 2018 - Düsseldorf, Germany).
