In the early 1950’s Walter Wojan set out to prove to a skeptical U.S. window industry that well-made aluminum windows and doors could be energy efficient, durable, maintenance-free and economical.

Mr. Wojan’s company first introduced his line of extruded aluminum storm windows and doors in 1953, and the product line has since continued to grow. The privately-held firm remains headquartered in Charlevoix [SHAR-la-voy] Michigan.

Double-glazed prime windows and doors were brought to market in 1958. And in the early ‘60’s, Wojan Window & Door Corp. became a true pioneer in the design and production of energy efficient windows by utilizing double-sash construction and a unique thermal barrier.

Well-positioned for the energy crisis of the ‘70’s, Wojan’s M-35 triple-glazed windows demonstrated the insulating value of airspace at helping stop the transference of heat or cold between the interior and exterior environments. The M-35’s attributes continue to be of beneficial appeal for those applications requiring greater acoustical performance and energy efficiency.


Over the last four decades, Wojan Window & Door has introduced a number of new window models, as well as sliding glass doors, and terrace doors. Most notable are the 3 1/4″ frame M-950, the M-950B Blast-Resistant model, the 1600H Historic Double-Hung window series approved by the National Park Service, and most recently, the architecturally-rated TD5500 Terrace Door.

Today, Wojan has two plants manufacturing custom quality aluminum windows and doors – a 70,000 square foot facility in Charlevoix which also contains an AAMA Certified product performance test bay; and a 60,000 square foot facility in Coldwater, Michigan – strategically located between Detroit and Chicago.

The family-owned corporation has been led by Walter Wojan’s son, Dennis, since 1970 and has since expanded to a 3rd generation. A graduate of the Farmer School of Business at Miami University, Dennis’ son Michael is the company’s VP of Business Operations, and leads the estimating team on a day-to-day basis.
