Thermal barriers separate the interior and exterior of the aluminum frames, dramatically reducing the transfer of heat and cold. Double weatherstripping and deep interlocks stop wind and water leaks. Double-paned glass insulates and provides optimum energy efficiency. Optional Low-E coatings and Argon gas boost R-values even more.
Thermal windows are maintenance-free, made from strong, precision-engineered aluminum, with a durable powder coat finish that never needs painting. The tilt-in sash makes cleaning from inside your home quick and easy. At Thermal Windows OKC, we're proud of the quality of our products, installation and service.
If a problem occurs that is covered by our warranty, you have the comfort of knowing that you will be dealing directly with us, the manufacturer who is familiar with you and your order, not a factory in a distant state. Since proper installation is a crucial part of window and door performance, our Lifetime Warranty only applies to products installed by Thermal Windows, Inc.

We have used Thermal twice for 2 of our homes. Once in 2013 working with George Bowers and once in 2021 working with Dee Cox. We couldn’t be happier with the quality and value of the windows, and their customer service and overall professionalism is second to none. Both of our houses had old, drafty windows, and we noticed an immediate improvement with both installations, notably with the noise reduction and energy savings. The windows also greatly improved the look and value of both houses. We cannot recommend Thermal Windows enough and will not think about using anyone else for our window needs

Thermal windows is top notch in every way. Dee came out and measured our windows to be replaced. She's super professional and so kind! I dealt with Brian as well and he was very friendly and no less professional. The final cost was very reasonable and If I ever need any windows again I'll use no one else! I couldn't be happier!

We recieved several estimates from local window replacement companies, and went with Thermal Windows due to window quality and price for whole house replacement windows. The estimate process from initial in-home estimate to formal estimate in their OKC office was a good experience and well explained. We had the lead paint inspection and an installation professional come out to the house to look at the actual replacement process. The installer crew announced their arrival time as expected and surveyed the existing windows and went to work. It was a good 2 man crew that has worked together for a

Couldn't be more pleased with Thermal Windows Inc. They came out to measure. Arrived on time. Provided plenty of color choices. Came back to remeasure then shortly thereafter came back to install which took less than 2 hours for 4 windows. Cleaned up and on their way. The windows are exactly what we wanted and we'll be ordering from them again!!

My wife and I had our windows from Thermal Windows, Inc installed yesterday, 12/10/20. We could not be happier with our new windows. They have improved our home so much, that it is like living in a new modern home. We are so glad that we did this. Our sales rep, George Bowers, showed up at our home right on time and was a real pleasure to deal with. He assessed our measurements in short order, then sat with us and laid out all our options. He was very knowledgeable about his product offerings. He was very patient with us as we changed our minds several times about what color and products to use

This company has been amazing to work with. We had our windows installed yesterday and they are beautiful! The entire staff from the salesperson to the guy that did the measuring to the follow up with updates to the 3 men that installed them has been top notch. They even called this afternoon to make sure everything was done to our satisfaction. I highly recommend them! They are extremely professional but also personable!! We will definitely use them in the future!!

We got our windows two months ago. We recommend this company highly. We had one very minor issue. They fixed it to our satisfaction. The windows have made a huge difference in being able to keep our house cool this summer. They also look great! I was thrilled that we could work with a local Oklahoma company!

Our windows from Thermal Windows of Bethany were installed last week. They are beautiful windows and we couldn't be more pleased with the appearance and quality. The installation was careful, and the guys cleaned up really well. As I watched the team install the windows, I realized that they were working slowly and carefully, and it dawned on me that this is a company that from ownership and management on down is careful to do quality work and to take the time necessary to get everything right the first time. The guys spent four days installing windows in our entire house, and it made me feel really
