Therma-Tru Doors is the nation’s leading manufacturer of fiberglass and steel exterior door systems and the brand of entry doors most preferred by builders and remodelers.

As a part of consumer products company Fortune Brands, Therma-Tru joins a great family of leading home products brands, including Moen, the #1 faucet brand in North America, MasterBrand Cabinets, the #2 kitchen & bath cabinet business, Master Lock, the world’s #1 padlock brand, and Waterloo Industries, the leading manufacturer of tool storage products.

Founded in 1962, Therma-Tru pioneered the fiberglass entry door industry with the introduction of the Fiber-Classic wood-grained door in 1983. It soon became the standard for the entry door industry. Therma-Tru built on this innovation with the introduction of the Classic-Craft Oak grained door collection. The 1999 introduction of Smooth-Star smooth fiberglass again raised the bar of innovation in the fiberglass door industry.

Today, Therma-Tru is once again revolutionizing the marketplace with the elegant new Classic-Craft Mahogany Collection, the charming new Rustic Collection and has extended its expertise to patio door systems with the industry’s most innovative collection of fiberglass hinged and sliding patio door systems. Therma-Tru offers complete entry and patio door systems, including handcrafted decorative doorlites and sidelites, transoms and door components through a national network of distributors, lumberyards and retailers.
