ABSTRACT:
An insulated sliding window assembly includes a compression seal between a mobile sash and the window frame. A locking mechanism cams the mobile sash to move both parallel to and transverse to the plane of the window frame, causing the sash to compress the seal and to be positively locked to the window frame. The moveable sash of the invention includes rollers which roll on guides. The sliding window assembly also includes mechanisms for releasing and pivoting the exterior moveable sash to a maintenance position.
