Therma-Tru Doors

Alside Windows & Doors​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."
