Abstract An insulating window system is provided wherein a window track is secured on a frame outlining the window. The window track includes a pair of spaced jaws defining between them a channel with a semi-oval cross-section. A glazing frame having a base member with two outwardly extending arms for engaging the inside surface of the jaws, and securing the frame arm to the track. An insulating strip extends between the arms and fills the space not occupied by the arms when they engage the jaws within the channel. The glazing frame includes a pane holder which includes the base section of the jaws and a face section overlaying the back and connected thereto by an end section, all forming a glazing channel into which the glazing pane sets.
