A sashless window structure which is economical in building construction and in rehabilitation of old buildings. The structure includes unique track members, preferably extrusions, having a flat base strip and a multiplicity of resilient flat finger strips mounted lengthwise along one surface of the base strip and having enlargements at their free edges. The finger strips define channels therebetween which receive plastic window panes which, principally by virtue of the unique track member configuration, are both slidable in the channels and firmly held in place when released.
