Therma-Tru 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 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.
