SolarSmart is a self-tinting, high performance glass. It automatically darkens in the presence of direct sunlight to block heat, glare, and damaging ultraviolet light.
It is completely solar activated, powered, and controlled, requiring no wires, electronics, external power, or user involvement. This simplifies installation and maximizes potential energy savings. It has passed NREL durability and exposure tests and meets the ASTM E2141-06 standard for long-term, maintenance-free performance. BUILDINGS.com
