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.* Our 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.
