Expect more from Thermo-Tech Premium Vinyl Windows and Doors. At Thermo-Tech, we build in more quality, so homeowners can expect more energy savings, more beauty and more comfort.
 
Thermo-Tech offers vinyl windows and doors in a wide array of standard sizes that make new construction a breeze. Or we can build replacement windows or doors for nearly any replacement project. No need to reframe. Simply order the size windows that you need—all the way down to 1/16th-inch increments—and we'll deliver.
 
Based in Sauk Rapids in Central Minnesota, we know the importance of manufacturing windows for all climate extremes. And our growing network of over 500 experienced dealers extends throughout the Upper Midwest, including locations in the U.S. in Minnesota, Wisconsin, North Dakota, South Dakota, Iowa, Michigan, Illinois and Indiana as well as Canada.
 
Every window and door we manufacture for either replacement or new-construction projects is built to order with one thing in mind: your complete satisfaction. Learn more about our premium Thermo-Tech windows and doors today.
