Therma-Tru has established a position in the building materials industry through the manufacture and sale of insulated door systems. The company, founded in 1962 by David K. Welles Sr., has developed the reputation as a creative corporation utilizing an aggressive market strategy with major emphasis on product research and development. Between corporate headquarters in Maumee, OH, and manufacturing facilities in Roland, OK, Fredericksburg, VA, Butler, IN, and Matamoros, Mexico, Therma-Tru employs over 2,000 full-time individuals. We have 150 certified distributors throughout the domestic U.S. and the international marketplace with annual sales in excess of $365,000,000.

By introducing products made of advanced fiberglass compounds, Therma-Tru redefined the traditional concept of higher performance building materials. Advanced manufacturing technology assures products superior in quality and versatility that can be delivered quickly.

Introduction of the Fiber-Classic door to the national housing market in 1985 was a clear illustration of Therma-Tru's strategic philosophy. It affirmed Therma-Tru as the innovator in the building materials industry. The 1994 introduction of the Classic-Craft® door and the 1998 introduction of a complete line of Fiber-Classic sliding and hinged patio doors positioned Therma-Tru as the indisputable industry leader.

The Therma-Tru quest for quality and value continues in each of their product lines. The 1999 introduction of Smooth-Star® is predicted to revolutionize the fiberglass door industry. This intuitive new door boasts the same durable qualities of fiberglass, has a smooth surface and is competitively priced to steel.

Therma-Tru's move towards greater use of reinforced fiberglass compounds and development of extruded and injection-molded materials has been motivated by this philosophy: We desire to develop, manufacture and control all aspects of the Therma-Tru Door System and believe the potential and performance of alternative materials is virtually unlimited.
