Guardian Glass brings the process and results of glassmaking to new levels, applying deep knowledge of chemistry, physics and advanced technologies to create glass with optimal light transmission, clarity and integrity for custom treatments and fabrication. As part of the Guardian Glass manufacturing process, sputter-coatings can be deposited on the glass to support application based energy performance and occupant comfort. These coatings also facilitate aesthetics involving light transmission, color and reflectivity.
