Cardinal Glass Industries is considered one of the world's leading providers of superior-quality glass products. From the melting of the sand to produce clear float glass to the vacuum sputtering of silver to produce low-emissivity coatings.

Cardinal Glass Fargo specializes in insulated glass. Insulated glass is double-pane and triple-pane units separated by spacers and filled with argon; panes can be annealed, tempered, or coated.
