Abstract: An automatic window assembly for installation in the roof of a building. The automatic window assembly is motorized and has a window pane that slides or tilts open or closed. The window assembly is mounted in an opening cut into the roof by attachment to an elongated template which is mounted on the roof and surrounds the opening. The template has a material thickness considerably less that that of the roof and has an opening formed in one end sized to accommodate the window pane. The template is positioned over the opening in the roof to provide the window pane opening at one end and an area of reduced material thickness at the other end. When the window is moved to an open position, the moveable pane slides under the template. A preformed and prefinished chute extends from the window to the ceiling of the room to allow with window to communicate with the room.
