A window having a window panel that slides in a frame and at least one balancer that is secured to the window panel is disclosed. The window is of the tiltable hung type having a vertical operating position in which the balancer slides with the window panel in the frame and a tilted position in which the balancer remains secured to the window panel. The balancer includes an extensible member having a first end operatively coupled to the balancer and a second end operatively coupled to a frame so that the balancer can exert a force on the window panel to assist against the force of gravity when the window panel is in the vertical operating position. A method of constructing a tiltable hung window with a balancer secured to the window panel is also disclosed.

Window panel balance apparatus and method

A window having a frame, two fixed jamb liners, a sash, and two hinged weatherstrips. The fixed jamb liners are secured to the frame such that they do not move laterally with respect to the frame. The hinged weatherstrips include a rigid sash bearing member hingedly connected to a second member. The sash bearing member is capable of moving laterally toward and away from the fixed jamb liner such that it provides an effective seal between the sash and the fixed jamb liner.
