It's no longer necessary to use a custom door to bring light into a dark space. Tacoma, Wash.–based Signamark's Privacy Door offers a center panel of opaque glass that permits light but blocks views. The door has an engineered wood core covered with select clear veneer in stained pine or stained red oak. It also comes in a primed version and in 24-, 30-, 32-, and 36-inch widths.
