A pre-fabricated window assembly for flush-appearance glazing comprises a conventional single-pane or dual-pane assembly. In the latter case, the spacer elements are inset from the peripheral edges of the window assembly. One of two types of extrusion is provided along each peripheral edge of the window assembly which provides a bonding surface to which the flush mounted lite is adhered by means of a bonding cement plug. The extrusion on one side of each pair of opposed sides of the window assembly is provided with a quick push-on or hook-on connector which mates with a complementary connector on the mullion or grid frame. The other extrusion on the opposite side of the window unit, for each pair of opposed sides, is similarly configured, except that the connector is a permanent connector for permanent securing of the extrusion to an appropriate mating fastener on the grid frame. Where a dual glazed window assembly is used, each of the extrusions is provided with a channel in which the peripheral edge of the inboard lite is mechanically gripped. The extrusions, in that event, are also provided with a rib or flange forming with the inner side of the inboard lite a recess into which a bonding agent may be placed to adhere the inner lite to the extrusion. The extrusions and the bonding cement are all applied in the factory to make the complete pre-fabricated window assembly.
