CA 2427172

A window having a frame with at least two oppositely disposed side members, a top member, and a bottom member. Operably connected to each frame side member is a jamb liner having a front face and at least one jamb channel. Mounted within the frame is at least one sash having two oppositely disposed sides. The sash tilts away from tree frame for easy cleaning. Within each jamb channel is a locking slide block for slidably and rotatably mounting the sash to the frame. A plough extends from the face of each jamb liner in the direction of the apposite frame side member. Each side of the sash has a sash groove for slidably mounting the sash in the frame by receiving adjacent ploughs. The plough and sash grooves have interlocking edges which engage to resist unintentional tilting of the sash. The jamb liner is mounted for lateral displacement from a first position wherein the plough is engaged with a sash groove to a second position wherein the plough is at least partially retracted from the groove so that the window can be tilted. There is a counterbalance operatively connected to the frame which has a counterbalance tab with an elongated portion having a flange proximate one end for connecting the counterbalance to the locking slide block.
