Abstract
A jamb liner is provided for a window assembly including a frame and a sash operably mounted in the frame by use of the jamb liner. The jamb liner includes a sash-engaging portion having at least one pair of opposing wall sections and a bottom wall section defining a channel. An air-sealing portion extends from the opposing wall section for sealingly engaging the frame to prevent undesired flow of air between the jamb liner and the window frame. The air-sealing portion includes a root wall section that extends at an angle to one of the opposing wall sections, a resilient wall section that extends from the root wall section, and a frame-engaging wall section that extends from the resilient wall section. The resilient wall section connects the root wall section to the frame-engaging section and has a thickness which is generally greater than that of the root wall section and frame-engaging wall section, at least in certain areas, as well as a convexly curved outward configuration which is preferably larger and more extensive on one side than on the other, to provide improved biasing of the jamb liner between the jamb and the window sash which reliably and strongly urges the jamb liner toward the stiles of the sash whereby an enhanced weather seal is provided and maintained.
