Home | Manufactured in the U.S.A.

Every window and door from Great Lakes® Window is made with care in the U.S.A. We employ over 450 associates at our manufacturing facility located in Walbridge, Ohio and work with over 475 dealers and distributors throughout the U.S. As a result, we have produced more than ten million vinyl replacement windows and doors for American homeowners, helping them create a more comfortable and energy efficient home.

All the materials needed to make our windows and doors, including the glass and many other components, are made here in the United States. And our proprietary vinyl formulation comes from our parent company, Ply Gem, a leader in pioneering performance home exteriors, which is headquartered in Cary, North Carolina.
