Viracon, a single-source architectural glass fabricator, has introduced the latest coating in its products.
A high-performance glass coating, VUE-30 offers architects and designers visible light transmittance relative to the solar heat gain performance.
VUE-30 meets both the aesthetic and energy-performance requirements of today’s design environment. According to the company, the percentage of light through the glass allows designers to maximise window-to-wall ratios, while its performance exceeds both those of other coatings in its industry and current domestic energy code requirements – including ASHRAE 90.1 requirements for sustainable design.
When VUE-30 is applied to a ¼” (6mm) clear substrate, the performance provides a solar heat gain coefficient of .18 and a visible light transmittance of 31%. The result is a superior light to solar gain ratio of 1.72. The Department of Energy’s Federal Technology Alert publication of the Federal Energy Management Program views an LSG of 1.25 or greater to be Green Glazing/Spectrally Selective Glazing.
