Perhaps no single architectural feature is more emblematic of Western living than the glass sliding door. For more than 50 years, sliding glass doors have opened our homes to generous natural light and views, simultaneously giving us easy connections with decks, patios, and gardens. Contemporary sliding, or gliding, doors have come a long way since yesteryear''s aluminum sliders, infamous for their stark appearance, sweating frames, and cold glazing. Today, a new generation of high-quality models offers energy efficiency, durability, safety, and contemporary style. Size and style Sliding doors come in a variety of sizes. In addition to the standard 6-foot, 8-inch height, they''re made 6 feet, 11 inches tall or even 8 feet tall. You can also buy three- or four-door-wide configurations that are as wide as 16 feet. And sliders are made with one fixed panel and one sliding panel, or with both panels sliding. Most manufacturers extend your design options by providing matching rectangular and roundhead transom windows. Some large manufacturers offer several sliding-door lines with a range of prices. You''ll find doors that have wide rails and stiles (horizontal and vertical framing elements) like French doors, and doors with thinner rails and stiles that maximize glazing.

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.
