Welcome to Therma-Tru, the most preferred brand of exterior doors in the business. Year after year, building professionals rank us # 1- as the brand they use most, and as the most innovative company in fiberglass entry door and patio door systems. It's a reputation we've been building for more than 40 years.            

In 1983, we pioneered the first ever fiberglass door. It achieved the look and feel of real wood grain, but eliminated the inherent problems of wood-cracking, splitting, swelling and rotting. Today, we are the acknowledged industry leader in entryways with proven system designs, superior features, continuous innovation and an unwavering commitment to safety, quality and craftmanship.           

No one offers you a wider array of door styles and decorative glass options- or greater value.
