Great Lakes Window started in 1981 manufacturing vinyl replacement windows out of a small warehouse in downtown Toledo, Ohio. Throughout the next five years, Great Lakes Window grew its capabilities and  began using an innovative new manufacturing process in the industry known as pinch fusion welding. 

The company has set industry standards with a number of firsts including:

• Manufacturing vinyl windows with an argon gas insulator
• Constructing a vinyl frame with patented R-Core® insulation
• Offering options such as decorative glass, solid brass hardware, a three-point locking mechanism and recessed tilt latches
• Creating laminated wood grain interior finishes
• Providing homeowners with a transferable, lifetime window warranty

As its growth continued, the company moved out of downtown Toledo in 1986 and into new headquarters in Walbridge, OH. This 6-acre, 500,000-square foot manufacturing and office facility currently houses over 450 employees who serve the more than 750 active Great Lakes Window dealers and distributors. Great Lakes Window has now custom-made more than eight million vinyl replacement windows and doors for homeowners in 48 states.
