A ventilation pane assembly for making a panel door or window, comprising two hollowed face panels at two opposite sides, an intermediate frame at the middle, a fixed perforated panel fixedly set between said intermediate frame and one of said two hollowed face panels, and at least one movable perforated panel movable set between said intermediate frame and the other hollowed face panel. Moving the movable perforated panel in one direction causes the vent holes thereon to be aligned with the vent holes on the fixed perforated panel for ventilation; moving the movable perforated panel in the other direction causes the vent holes thereon to be deviated from the vent holes on the fixed perforated panel so that air current is stopped from passing through the ventilation pane assembly.
