Claim 15:
16. A louvre window having:
a frame, the frame having a head, a sill and at least two jambs;
a drive bar located in one or both of the jambs that is movable by a handle;
a plurality of blades located within the frame and connected to the drive bar by a pivot drive connector, such that movement of the drive bar urges the blades to pivot, each blade having:
a first windowpane attached to the blade; and
a second windowpane attached to the blade,

wherein operation of the handle causes movement of the blades between an open position and a closed position, wherein in the closed position the first windowpanes are aligned to form a barrier against airflow and the second windowpanes are aligned to form a barrier against airflow and in the open position the first windowpanes are pivoted out of alignment to allow airflow and the second windowpanes are pivoted out of alignment to allow airflow,
wherein each blade further includes a cap member between the first and second windowpane, and
wherein each blade further includes a sliding member mounted to be movable in a second direction and to which the first windowpane is attached, the sliding member having an upper end extending over the first windowpane, and wherein the cap member has a lower end extending below second windowpane such that, when the blades move from the closed position to the open position, the lower end of the cap member of an upper blade abuts the upper end of the sliding member of a lower blade to urge the first windowpane of the lower blade in the second direction.
