Thermatru’s 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.”
