Patent

CA 2062919

The disclosure is directed to a jamb liner for a double hung window. A length of the jamb liner is mounted to and overlies each of the jamb sides defining the window opening. Each jamb liner has a front profile corresponding to the side of the associated sash to slidably retain and guide the sash. The jamb liner is extruded from a plastic material that is at least semi- rigid. Coextruded on the rear face of the jamb liner is are a pair of longitudinal spring hinge members each having a first portion contiguous with the jamb liner formed from a resilient material having a spring characteristic, and a second portion extending from the first portion formed from a plastic material that is at least semi-rigid. In mounting the window assembly into the jamb opening, the spring hinge members bendably and springably engage the associated jamb sides to generate a uniform biasing force on the sides of the sashes.
