Abstract
A fixed sash window comprises an outer frame within which there is fixedly mounted a sash including an inner frame embracing the periphery of a panel of glass or like material. The outer frame has formed therein inwardly opening grooves for receiving respective tongues projecting outwardly from the inner frame. The inwardly opening groove in either the sill or header of the outer frame is defined in part by a snap-on batten occupying part of a recess formed longitudinally in the sill or header along one of its inside edges. The inner frame is made smaller in size than the outer frame, to such a degree that gaps are formed therebetween to accommodate sealing strips of rubber or the like which are dually effective for weathertightly sealing the gaps and making the inner frame immovable with respect to the outer frame.
