America's most preferred entry door brand — setting the standard in fiberglass door innovation since 1962
Therma-Tru Doors, a division of Fortune Brands Innovations, pioneered the fiberglass entry door industry in 1983 and has remained its uncontested leader ever since. Based in Maumee, Ohio, Therma-Tru is America's most-preferred entry door brand among builders and homeowners alike. Their doors combine the authentic look of real wood with the superior performance of fiberglass, offering unmatched durability, security, and energy efficiency. Every Therma-Tru door is backed by decades of engineering innovation and rigorous testing.
Therma-Tru invented the fiberglass door and continues to lead the industry. Their doors resist denting, rusting, and rotting while beautifully replicating the look of real wood grain.
Every Therma-Tru door undergoes the Tru-Defense system of testing — a proprietary battery of performance tests that exceed industry standards for security, weather, and structural integrity.
