SunGuard® eXtraSelective
SNX 62/27
How low can solar heat gain go?

Bright natural light makes spaces inviting and improves the quality of life for building occupants, but it has traditionally come at the expense of higher air conditioning costs. SunGuard® SNX 62/27 sets Guardian’s new standard for maximising light and minimising heat. On clear and Guardian UltraClear ® glass, the coating has a highly transparent look, or the coating can be applied to Guardian’s specialty float options for grey or green colour. By admitting more light than ever, SNX 62/27 is a top choice for daylighting.
