Abstract
A ventilated window for oven doors comprising at least two spaced parallel glass panels mounted in a frame surrounding the peripheral edges of the panels, said frame being comprised of spaced glass receiving channels and an integral spacer portion between the channels, the spacer portions at the top and bottom of the window being formed with angled fins or vanes to provide relatively narrow elongated louvers which extend substantially the entire width of the window for directing a flow of cooler air upwardly through the space between the glass panels to replace the hotter air therein.
