Abstract
A jamb liner is mounted in the side jamb tracks of a window frame to mount window units of double hung windows for slidable movement between opened and closed positions. The liner includes transversely spaced channel guides, each guide mounting a guide member that is attached to the adjacent window unit. Flanges are joined to the guides for forming a close fit with the adjacent window unit while, to each guide, there is joined a wing to form a seal with the web of the adjacent jamb to block fluid flow between the window units and the side jamb from one transverse side of the unit sash to the other. The wings of the liner are arcuately curved to transversely diverge from one another in a direction toward the jamb web. The wings are of a substantially greater resiliency than the rest of the liner, said rest of the liner being semi-rigid and made of extruded plastic.
