It was a bold innovation for the home-building market when we introduced an entryway door that looked as beautiful as wood and was more durable. At Therma-Tru, we have been revolutionizing the industry from the start—a spirit you can continue to expect from the leading entry door brand most preferred by building professionals.*

1962 – 1984

Our roots go back to 1962 when David Welles, a retired Owens Corning executive, purchased a bankrupt building supply company in Toledo, Ohio. In 1982, 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.”

1985 – 2002

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.

2003 – 2016

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.
