A spacer bar for use in double glazed windows is disclosed. The spacer bar is an elongated tube or conduit having a generally rectangular cross section. The spacer bar has two pairs of opposing planar faces. Each planar surface of one pair lies against the interior surface of one of the glass panes of the double glazed window and one planar surface of the other pair faces the space between the panes and the other planar surface of said other pair faces the atmosphere. A small diameter tube passes through the surface facing the atmosphere. The portions of the small diameter tube lying on either side of the conduit surface are bent downwardly. The portion of the small diameter tube which lies inside the conduit is bent downwardly and extends to a point at least 5 inches below its entry point and the other portion of the small diameter tube which lies outside the conduit is also bent downwardly so that it lies adjacent to and generally parallel to the outer face of the conduit. The planar surface of the spacer bar which faces the space between the panes has a small opening in it which lies at least about 5 inches from the interior end of the small diameter tube. A double glazed window as fitted with the spacer bar as above described is also disclosed.
