Therma-Tru Doors first created the fiberglass entry door category over 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. Fortune Brands, an $8 billion leading consumer products company, brought Therma-Tru into its family of premier brands in 2003.

Why Us?

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. In addition, Stock Building Supply, a Builder Partnerships associates, is one of our preferred suppliers. By purchasing our product through Stock, you can earn additional incentives.
