THERMO-TECH WINDOWS AND DOORS

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.
