When the sun starts shining and the temperature rises, SolarSmart self-tinting glass from Innovative Glass automatically darkens to reduce light and keep interiors cooler. Then, as the sun sets, the tint fades. Since the glass is 100% solar-activated, it requires no power, wires, or control systems, which simplifies installation. It’s the perfect product for curtain walls, atriums & skylights. The need for blinds and drapes is reduced, and in many cases buildings with self-tinting glass can see between 20 and 43% in annual energy savings. Professional Builder
