Raw Glass

Quality from the Beginning

Top of the line residential window manufacturers rely on a constant supply of high-quality float glass. At Cardinal FG Company, such quality is what you can expect–our seven U.S. FG facilities will provide it for you every time.

The pursuit of perfect glass

Cardinal looks ahead of the industry by using new technologies that will meet even tomorrow’s marketplace. Our constant growing spirit takes glass manufacturing to a higher level. Our modern furnace design gives Cardinal an excellent system for producing float glass in a 24/7 environment.

The capabilities built into the process give our operations maximum flexibility to produce the many different thicknesses of glass – from 1.6 to 7mm that are required for the residential market.

A vision of excellence from
production to shipping.

Our practical packing system preserves glass quality. State-of-the-art glass packing is done on automatic or manual spur lines, depending on size. The need for clean production has resulted in a system that minimizes contact with glass surfaces during the packing phase. A capping system uses 90° rotators, barrel turnovers, robots, and stackers to ensure proper glass orientation for downstream operations.
Our computerized inventory program provides accurate supply intelligence down to the very lite. The glass warehouse accommodates storage of up to 25,000 tons of glass for our customers. To ensure that we have the proper on-hand inventory, we have a tracking and stock locator system that connects this inventory with current and projected customer demands.
Our patented rack system minimizes handling. To reduce the times a pack of glass is handled, we introduced a system called a collapsible A-frame. It ships the glass from our floor via standard sized trailers directly to the customer’s line for processing. The racks need minimal separating or bracing materials, which saves time and factory space in the process and reduces waste.
Intelligent Quality
In addition, with our exclusive Intelligent Quality (IQ) program, customers can depend on the quality and consistency that our products are known for. IQ represents a series of quality control processes that guarantee that glass always meets or exceeds specifications. In our float glass facilities, we installed IQ inspection systems in these areas:

Did you know?

Float glass plants are enormous–over 350,000 square feet under each roof.

Each plant uses $500,000 of natural gas and $85,000 of electricity every month.

Float plants run nonstop 24 hours a day, 365 days a year.

Each FG plant ships 35-40 trucks of glass every day, at almost 35,000 square feet per truck.

Glass is cut in sizes as small as 16″ x 20″ to as large as 130″ x 204″.

These systems as well as our industry-leading inspection processes are the assurance that Cardinal glass will exceed specification and expectation. Great glass helps make great windows, so manufacturing superior float glass is always our stated goal.
