ABSTRACT:
An automated window system and method for a building utilizes a pair of gas springs to bias a window panel outward from a corresponding frame. A force opposing the gas springs is supplied by a motor driven spindle selectively winding and unwinding a cord coupled to the window panel sash adjacent the jamb portion of the frame and window. The cord is slidably retained to the jamb portion of the window sash through a pair of threadable pulls in order to equalize the forces supplied opposing the gas springs in the event of uneven winding of the cord due to buffeting or other forces while the window panel is being moved between an "open" to a "closed" position thereof.
