Abstract: A window or door assembly having a secondary sash hinged to a prime sash and movable between a closed position and an open position toward an interior region. The prime sash is coupled to a frame. A compressible member biases the secondary sash toward the open position. A latch assembly is provided including a plurality of retractable latching elements each biased to an extended position to retain the secondary sash in the closed position. The latch assembly includes a sliding operator accessible from the interior region and slidable along an edge of the secondary sash to sequentially displace the retractable latching elements to a retracted position sufficient for the compressible member to move the secondary sash toward the open position.
