Therma-Tru® Doors

Therma-Tru® Doors first created the fiberglass entry door category 25 years ago with the introduction of our Fiber-Classic® wood-grained doors. Today, we are the nation's leading manufacturer of fiberglass exterior door systems, and we are the most preferred brand of entry doors by builders and remodelers. Fiberglass doors simply outperform wood doors and steel doors.

Since our beginning in 1962, Therma-Tru® Doors has been revolutionizing the home improvement industry with innovations and technologies in door systems, improving millions of homes across the country with original door styles such as the wood-grain lines of Classic-Craft® Oak, Mahogany, Rustic and American Style Collections™, Fiber-Classic® and Smooth-Star® fiberglass doors, and patio door selections.
