Therma-Tru Doors

Your Entrance to Extraordinary

It was a bold innovation for the home-building market 25 years ago when we introduced an entryway door that looked as beautiful as wood but performed with the durability of steel. But revolutionizing the industry is what you can expect from the nation's leading manufacturer and most preferred brand of fiberglass and steel exterior door systems.

Therma-Tru's 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.

"People just couldn't believe it," says Deke Welles, son of founder David K. Welles and President of Therma-Tru from 1989 - 2001. "The product that looked so good was actually made of fiberglass."

In September 2009, Therma-Tru and Fypon — the brand name leader in the urethane millwork — merged together due to many synergies, including complimentary products. This merger provides a great opportunity for both brands. For more information on Fypon and their products, please visit www.fypon.com. For more information on the merger, please see our news release, under the News & Event section.
