SunGuard® eXtra Selective

SNX 50

Brands SunGuard SNX

Boost thermal insulation, banish energy costs

By delivering world-class selectivity, eXtra Selective (SNX) 50 helps reduce energy costs by lowering the demand for artificial lighting, air conditioning and heating.

With a transparent appearance, low reflection and consistent colour, it is the ideal choice for completely glazed facades.

It delivers optimum thermal insulation when used in a standard double-glazed unit.

Excellent selectivity

Combining high solar protection with high light transmission

Uniform appearance and performance

Neutral, transparent colour and low reflection

Can be laminated

For safety, security or acoustic applications

Unique patented foil

Protects glass during processing

Color Disclaimer Color Disclaimer

Displayed colors are intended to represent actual color. Color is a function of light and reflectivity and cannot be accurately portrayed online. Actual glass samples should be used to determine color. Please order a sample and discuss color with your Guardian Architectural Design Manager to ensure you are pleased with your SunGuard selection before ordering glass for your project.

Thermal Stress Disclaimer Thermal Stress Disclaimer

The thermal stress guideline is only a rough guide to the thermal safety of a glazing. Other factors such as large glass areas, shapes and patterns, thick glass, glass damaged during shipping, handling or installation, orientation of the building, exterior shading, overhangs/fins that reduce wind speed, and areas with high daily temperature fluctuations can all increase the probability of thermal breakage. The results shown are not for any specific glazing installation and do not constitute a warranty against glass breakage.
