Therma Tru Doors

It was a bold innovation for the home-building market twenty five years ago when we introduced an entryway door that looked as pretty 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 provide firm in Toledo, Ohio. In 1982, the firm launched its Fiber-Classic style, the 1st fiberglass door on the market.
