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.

An insulating window unit with improved acoustic damping, comprising: an inner glass pane; an outer glass pane; a spacer frame connected to said panes around the peripheries thereof and spacing said panes apart to define a gas-filled compartment between the panes; and at least one membrane strip bonded to a face of one of said panes along an edge zone thereof and connected to said frame, said membrane strip being of a material and dimensioned to follow deformation of said edge zone without significant resistance thereto, said strip having a flexural stiffness substantially less than that of said one of said panes at least in the region of said edge zone, the bending resistance of said in said zone being by a factor of 10-2 to 10-6 less than that of said one of said panes whereby transverse oscillations of said one of said panes correspondingly deform said strip.
