A History of Therma-Tru Doors
Our roots go back to 1962 when David Welles, a retired Owens Corning executive, purchased a bankrupt building supply company in Toledo, Ohio. In 1983, the company launched its Fiber-Classic style, the first fiberglass door on the market, creating a product never seen before: An entryway door that looked as beautiful as wood but with exceptional performance.
"People just couldn't believe it," says Deke Welles, the founder’s son and President of Therma-Tru from 1989 - 2001. "The product that looked so good was actually made of fiberglass.”

In 1985, we opened a 60,000 square-foot plant in Butler, Indiana. Within 10 years, we developed and introduced the Classic-Craft fiberglass door, followed a few years later by our Smooth-Star collection. In 2000, we patented our full door system.
In 2003, Therma-Tru became part of the Fortune Brands Home & Security family. And in September 2009, Therma-Tru and Fypon — the brand name leader in the urethane millwork — merged to bring their complementary products to market together. To meet the evolving expectations of our customers, we introduced our DoorWays App in 2015 to help homeowners visualize new doors on their own homes.

Our legacy of innovation continues with an investment in our new Innovation Center, which opened in early 2018. Located in Monclova, Ohio, just minutes from our corporate headquarters, the Innovation Center is a 30,000-square-foot facility that houses our Research and Development and Product Management teams.
