Claim:
A closure assembly comprising: a frame; a prime sash coupled to the frame; a secondary sash hinged to at least one of the frame and the prime sash and movable between a closed position and an open position, the secondary sash having an edge; a compressible member that biases the secondary sash toward the open position when the secondary sash is in the closed position; and a latch assembly comprising: a plurality of retractable latching elements each biased toward an extended position to engage at least one of the secondary sash and the prime sash to retain the secondary sash in the closed position; and a sliding operator slideable along the edge of the secondary sash to sequentially displace each of the retractable latching elements one after the other to a retracted position to release the secondary sash sufficiently for the compressible member to move the secondary sash from the closed position toward the open position.
