What Is A Window Head Jamb?

Window head jamb, is the vertical component at the very top of the window frame. The window sash is pressed up against it. As a result, the head has to be strong enough to bear the force of the sash. It must also have a certain level of rigidity, as it is the point at which the window is locked.
