Glazing that manages solar heat gain while providing clear views out aren’t new to commercial buildings. But glass manufacturer
PPG is now offering the technology for residential applications. Its Solarban 67 glass features a neutral coating with a visible light transmittance rate of 55% for clear sightlines and a solar heat gain coefficient of 0.29 to improve a space’s energy efficiency. Offered as a standard ¾” dual-pane unit, the window can block more than 70% of solar heat in the summer, according to PPG, while a U-value of 0.25 helps retain heat during colder months.
