Thermal Windows, Inc. is closing in on four decades of quality window design and production. The company was founded by the late Bob G. Pool in 1980. From the beginning, Mr. Pool took advantage of his engineering background and many years of experience in the window industry to design and manufacture affordable, energy-efficient products. Starting in the 1950's, Bob and his father Cal sold awnings, storm windows and storm doors as Aluminum Window Products. From a modest location on 15th Street in Tulsa, the Pool family business has grown to become the dominant window company in the region. Today, Thermal's headquarters and manufacturing operations occupy over 235,000 sq.ft. Our custom-manufactured windows, sliding glass doors and terrace doors are found in homes, schools and commercial projects throughout the United States. Advanced manufacturing processes, combined with in-house research, design and testing programs enable us to provide continuous quality assurance. We monitor quality in our debridging, painting and insulating glass facilities to maintain a high degree of control over these critical areas of window production.
