Therma-Tru
(From their site) 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." Visit their site
