AGC announced today that its light control glass WONDERLITE™ has been selected for the Magic Sky Control panoramic glass roof available as an option for the new Mercedes-Benz S-Class Coupé, which was released on the European and North American markets on September 27, 2014.

The Magic Sky Control glass roof equipped with WONDERLITE is the world’s largest light control glass roof for automotive use that changes its color from transparent to dark blue just by pressing a button.

AGC’s WONDERLITE, a SPD1-based light control glass for vehicles, will contribute to increased comfort and energy savings of cars for the following features.

Three times larger than conventional light control glass roof

Covering an area three times larger than the existing product, the large-sized light control glass roof affords a unique open-air feeling whatever the outside conditions, and dramatically increases the lighting comfort inside the car.

UV & IR protection achieved with AGC’s special coating

WONDERLITE used for the Magic Sky Control glass roof has been applied with special solar control coatings2, which filter out sunburn-causing ultraviolet radiation and heat-producing infra-red radiations even in the transparent mode. Through the effective integration of its light control and special coating technologies, AGC provides drivers and passengers with an optimal driving environment and contributes directly to reducing the need for air-conditioning, thus lowering fuel consumption.

By leveraging its diverse materials and technologies, AGC will continue to offer high value-added products that help to reduce environmental load and create comfortable living spaces.

1. Suspended Particle Devices (SPD): thin-film technology in which particles inside laminated glass become aligned when an electrical voltage is applied, making the glass structure transparent.
2. Metal thin film coatings which, when deposited on the glass surface, give it greater insulating and/or solar control properties.
