Thermo-Tech Premium Windows and Doors traces its history to a generation ago, when our dad opened East Side Glass in the family’s garage in St. Cloud, Minnesota. It was 1953, the same year John F. Kennedy married Jackie Bouvier and the same year the first color television went on sale. It was a time of innovation. And a time of quality and craftsmanship.
Some things don’t change.
“I started working with my dad when I was twelve, sweeping floors and cutting glass. The knowledge and experience I gained from him helped to shape Thermo-Tech. All of my adult life, this is what I’ve known: the business of building a better window.”
John Ferkinhoff, President
When Thermo-Tech opened in 1993, we brought those same values to our premium vinyl windows and doors. We made a commitment then to build only products that we are proud to sell—products our dealers can be proud to sell. To us, that’s the surest way to deliver products homeowners are proud to use every day.
We’re still a family-owned company, and customer satisfaction means everything. So we meticulously manufacture standard and to-spec windows to fit new construction or replacement windows for residential or commercial projects. Accurately. And on time.
We’re continually working to create even better products, too. Tinkering with the production process. Testing new glass and framing ideas. Transforming advanced technology into stronger, more beautifully energy-efficient windows and doors with countless design options:
- Standard or custom sizes
- Classic and contemporary shapes
- With or without grids
- Easy-matching colors: White, Tan or Sandlewood
- Interior wood laminates in Light Oak and Dark Oak
