At Thermo-Tech Premium Windows and Doors, 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.
“In the several years that Avalon Homes has used Thermo-Tech Windows, we have seen a large change in both the product and service part of the building process. . . Your company has become very reliable. We are able to schedule the installers with the confidence that all the product will be there and that they can complete what they came to do. Thus, we have fewer return trips and charges. [Thermo-Tech’s Service Department] is always willing to take the time to talk to us about any concerns and scheduling of any needed repairs. We have gone from a company that has one to two window items on a final walk through to virtually none. My wife, who is not in the building business, would love to tell just how much she enjoys the ease of use and the hassle-free cleaning of the Thermo-Tech Windows in our new home. It is a true pleasure to work with your company. Thank you.”
Jonny Mills – Avalon Homes
“Thermo-Tech windows have proven to be an integral part of customizing our home. The flexibility of their design staff allowed us to create windows that are truly our own. Quality of the product is outstanding. They look great, function perfectly, and are a breeze to clean. (Even for those of us who hate washing windows!)”
Homeowner from St. Cloud, Minnesota
“We are the owners of a forty-four year old home filled with charm and character. Unfortunately, along with its charm and character came drafty windows. We were looking for a window in our kitchen area that would not only keep to the style of our home but also provide us with easy maintenance, energy efficency, and affordability. We found that at Thermo-Tech Windows. Due to the vinyl on the windows there is no outside maintenance required and the inside maintenance is a simple dusting — no more yearly varnishing or painting! Besides no more drafty windows we have also noticed a marked decrease in the amount of outside noise. The gentle bow of the window gives the illusion of bringing the outdoors in as well as giving additional depth to the room. We love our window and are looking forward to adding yet even more Thermo-Tech windows in the near future.”

“We are very pleased with the quality of our new Thermo-Tech patio door and windows. The installation process was very smooth and fast. Sixteen windows and the patio door only took a couple of days to install. The wood grain around the windows matched our interior wood perfectly. The first thing we noticed about our new windows was how quiet our house was, and how bigger and brighter our whole house looks. Our heating and cooling bills have decreased significantly due to our Thermo-Tech windows. Maintenance and cleaning are a breeze. We feel good about buying windows and doors made right here in central Minnesota and we know the quality is excellent.”

“When choosing a business associate, I always look for reliability, dependability, and honesty. When choosing a product, it must have superior qualities for an economical value. Working with Thermo-Tech Windows has provided me a business relationship that meets all my expectations, both from a relationship and product perspective. It has been a pleasure doing business with you and we look forward to many transactions in the future.”
