Fiberglass doors look like wood, but they don’t warp or rot like wood, or dent or rust like steel. In fact, a fiberglass door needs only a fraction of the maintenance wood and steel doors do. And the inside of a Therma-Tru fiberglass door is filled with an exceptional heat- and cold-resistant material that helps keep your home warm in winter and cool in summer.
