Abstract

An acoustically and thermally insulated window structure comprising two outer panes and at least one inner pane with an outer spacer interposed between the outer panes and at least one further spacer defining a gap between inner panes when a plurality of the latter are provided. One of the inner panes is spaced at a predetermined relatively small distance from a corresponding outer pane and a body of moisture-absorbent material is disposed in fluid communication with a space within the inner panes.
