Thermatru Windows & 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 and steel exterior door systems, and we are the most preferred brand of entry doors by builders and remodelers.

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

Not only has our attention to details in styling brought improved curb appeal and value to our customers’ homes, but our proprietary security systems and top-of-the-line weather resistance features built into every door we make, brings the comfort of a Therma-Tru Door home to its owner.
