Abstract
An insulating window structure has an inner glass pane spaced from an outer glass pane by a spacer frame extending around the panes so that the panes define between them, within the frame, a gas-filled space. According to the invention, at least one of the panes is anchored to the frame by a resilient connecting unit having a spring characteristic (restoring force plotted along the ordinate versus displacement plotted along the abscissa) which has a substantially horizontal portion at the center of this characteristic and at which the working point of the resilient unit is provided.
