With its simple, straight lines. Smooth 2-Panel Molded Interior Door from JELD-WEN is a natural fit with almost any interior architecture, contemporary or traditional. This door has an ovolo sticking profile and a smooth surface. Solid-core construction reduces sound transmission by up to 50 percent (compared to a hollow flush door). It also helps prevent the dents and dings of daily life. One way JELD-WEN supports sustainable construction is by using recycled materials in the production of our molded interior doors. In fact, these molded door skins are made using 80% recycled content.
