History of
Cardinal Glass Industries

Humble Beginnings

In the early 1960s, window manufacturers were experiencing an increasing demand for the convenience of insulating glass instead of storm windows. Existing IG providers, such as PPG and Libby Owens Ford (LOF) had product lead times of about a year.

Thus, ML Gordon Sash and Door Company decided to manufacture its own insulating glass units.

In 1962, it created the subsidiary Cardinal Insulated Glass Co. A year later, Roger O’Shaughnessy joined Cardinal, which at the time had 12 employees, and in 1967, Mr. Gordon selected Roger to be the new president.

Since then, Cardinal has progressed from being a small facility in St. Louis Park Minnesota to being a worldwide provider of advanced glass solutions.
