Our founder, Maurice Blyveis, worked on aluminum airplane engineering during World War II. His dream was to start his own business utilizing his engineering skills. He wanted to provide a quality product that people would want. In 1950 he began making aluminum storm windows and storm doors in Grand Rapids under the name Ajax Aluminum.

Over the next 22 years Ajax grew in employees (including wife Marion and son Nate) while Maurice continued to sell his quality products to lumber yards. 1972 his son Nate took over for his father. The United States was in the middle of the "Energy Crisis" and demand for energy efficient products was increasing. As 1980 rolled around Nate brought Ajax into the vinyl replacement window business. Aluminum storms were about to become "a thing of the past."

Today Ajax is know throughout Michigan and northern Indiana as Polar Seal Window Corporation. It is still a family owned and operated business. Today, Nate’s son Jason is the General Manager. With 33 employees (21 have over 10 years of service while 7 have over 20 years of service) and 78,000 square feet, Polar Seal has grown tremendously from the old days. Yet some things have remained the same. Customer satisfaction is still number one. Polar Seal cares about making the best windows, providing unparalleled service, and being proud members of our community.

We know you have a choice when deciding what window is right for you. And we want to earn your trust everyday.
