The SunGuard® eXtra Selective range leads the way in state-of-the-art solar protective glass from Guardian. SunGuard SNX 50/23 helps to create a comfortable interior environment. Thanks to its world-class selectivity it lets in an astonishing 50% of natural daylight combined with only 23% of the solar heat. This will help to save energy costs thanks to a lower demand for artificial lighting and air-conditioning. SunGuard SNX 50/23 has a beautiful neutral transparent appearance and a low reflection, adding a sophisticated touch to the design of your building. Our tightly controlled manufacturing is able to deliver a consistent colour which makes the SunGuard SNX 50/23 the ideal choice for completely glazed facades. When used in a standard double glazing unit SunGuard SNX 50/23 delivers a U-value of 1.0 W/m²K, providing optimal thermal insulation. Guardian has an extended knowledge of glass applications and a team of highly qualified specialists who are there to advise you on our products and their use. • World-class selectivity: lets in 50% natural daylight, whilst reflecting 77% solar heat gain • Save heating costs during colder periods thanks to its very high insulation: U-Value of 1.0 W/m²K • Aesthetically superior thanks to its neutral transparent colour and its low reflection • Available on laminated glass for safety, security or acoustic applications • The heat-treatable (HT) and annealed versions are uniform in performance and appearance • Unique patented foil (TPF) to protect the glass during processing
