A jamb liner, or facing member, for movably mounting windows along their side edges in channels or runs, in which a concealed elongated chamber is provided for a coil spring or the like used as part of the balance or positioner mechanism by which the window is supported in different positions along the length of the jamb as it is opened and closed during use. Preferably, such concealed chamber includes an elongated wall which projects outwardly from the jamb liner and has an arcuate or other angularly-configured cross-section, such that it presents a generally closed appearance when viewed from a position near the window. Such chamber-concealing wall defines an elongated opening through which the balance device may communicate for access by the window ash, for supporting the latter and positioning it. In addition, a novel balance apparatus is disclosed which comprises a friction shoe configured to slidably move within the aforementioned chamber and frictionally engage a rib extending therewithin, as a function of and in response to the applied weight of the sash.
