Some of the most advanced coated glasses available today apply three layers of silver during the magnetron sputter coating process and the technology provides the glass market with the broadest level of selectivity. The selectivity refers to the ratio between light transmission and the solar factor or g value. The SNX68/28 coated glass products launched by Guardian Industries are the products with the most advanced technology and the best performance in the present market.
Architects today are asking for the highest light transmission combined with the lowest possible solar factor, desirably with U-value of 1.0W/m2K or so, while having natural and beautiful appearance. Guardian Industries’ SNX68/28 coated glass processed with triple-silver coating technology can meet the above various requirements. The product has a 60% light transmission and a low 28% solar factor reflecting 72% of the sun’s heat away from the glazing, and achieves an optimum selectivity ratio of 2.14.
