An apparatus for covering and uncovering a skylight opening. The apparatus has a parallel guide pair mounted on the outside of a framing surrounding the opening, a carriage with skylight movably mounted on the guides, and an actuator for moving the carriage over the guide's length. The guides extend a distance beyond the framing's right side sufficient to displace the skylight completely away from the opening. One end of a screen, large enough to cover the opening, is connected to the carriage's left side. The other screen end is mounted on a storage roller rotatably supported by the framing's left side. The roller's spring maintains screen tension so that, when the carriage is displaced away from the framing's left side, the screen is tautly pulled over the space between the framing's left side and the carriage's left side. One end of a shade, large enough to cover the carriage's opening, is positionable adjacent the carriage's left inside wall. The other shade end is mounted on a second storage roller rotatably supported by the framing's right side. The roller's spring maintains shade tension. A coupling device's left end is attached to the shade's one end. The device's right end can be coupled and uncoupled to the carriage's right side. When the device is coupled, that part of the carriage overlaying the framing's opening is covered by the shade. A rigid panel shade can also be used with the coupling device. The carriage can be remotely opened and closed and automated to open for smoke, and to close for moisture and intruders.
