Therma-Tru doors doors, which are made of fiberglass, have redefined the traditional concept of high-performance building supplies. The company pioneered the polyurethane foam core, now CEC-free, which offers five times greater insulation value than wood doors. Therma-Tru is also the first exterior door manufacturer to feature a full thermal break which prevents the transmission of custom heat and cold through the surface. Our doors are made of fiberglass so they won''t dent, crack, split or splinter, which means they eliminate callbacks for you. Therma-Tru recognized the need for a more durable, highly efficient door. In 1983, it introduced the first door, the Fiber-Classic. The door became so popular that today, Therma-Tru offers three door lines including fiberglass Classic-Craft, Fiber-Classic and Smooth-Star. For the builder and the customer, there''s a Therma-Tru door to add style and curb appeal to every home whether it''s the ultimate luxury residence or a starter home. Beautifully detailed, Classic-Craft and Fiber-Classic doors look and feel just like wood. Their durable fiberglass surface features a rich red oak grain, but unlike wood doors they don''t come saddled with inherent maintenance problems. Plus, they''re backed by a lifetime-limited warranty.

Now the nation''s leading producer of steel doors, Therma-Tru helped build the market for that product category. The effectiveness of that pioneering effort is reflected in the market share steel currently holds. For the past two decades company has focused its commitment to quality fiberglass and innovation on doors, the fastest-growing segment within the exterior door category. We were interested in differentiating ourselves from the rest of the market -- that''s the only way to be profitable in the long term recalling hiscompany''s motivation for pursuing fiberglass. Therma-Tru recruited a ream of engineers and assigned them the mission of developing a new product that would put perform both wood and steel. The team blended fiberglass and resins to invent a sheet-molding compound, as well as the tooling to transform those supplies into a door skin. After extensive laboratory and field testing, the fiberglass industry''s first door hit the market: the Fiber-Classic.
