A sliding screen window for a garage door may be built into new garage doors or may be sold separately for installation on existing garage doors. The window would generally, but not necessarily, be installed on the top panel of a garage door. The screen panel may be oblong in shape or may feature a decorative pattern of screened and non-screened shapes. Behind the screen is a plurality of transparent or opaque sliding plates that may be moved aside to allow air to flow through the garage door.
