Cardinal Glass Industries

Cardinal Glass Industries is a management-owned S-Corporation leading the industry in the development of residential glass for windows and doors. We have grown to more than 7,000 employees located at 37 manufacturing locations around the United States.

At Cardinal, we try to maintain a clear vision: design and fabricate the most advanced residential glass products in the industry.

We start with a heavy investment in research and development. Our three R&D centers in Minnesota, Wisconsin and Florida provide the basis for new advances in glazing fenestration.

We turn around those fresh ideas into useful products that regular homeowners can use. We provide a turnkey solution to window manufacturers: whether it starts with insulating glass, coated, laminated, tempered or just plain float glass, it is all designed to provide the latest in applied glass science.
