Abstract
An insulating window structure with improved sound-damping properties comprises an inner window pane, an outer window pane, a spacing frame holding the two panes apart so that they define a gas space between them, and a membrane-like yieldable member connecting at least one of these panes to the frame. The membrane-like member is in the form of a strip whose bending strength or stiffness is small by comparison with that of the pane to which it is bonded at least over the edge regions of the latter pane and the strip at which the bonding is effected. The strip is dimensioned and composed of a material such that transverse undulations developed at the edges of the pane are not resisted, i.e. the undulations along the edges of the pane are followed by the strip without significant resistance.
