Sealed insulating glass units with multiple-pane construction containing an intermediate taut, flexible heat shrunk plastic sheet are made using silicone edge sealant which exhibits a sheet creep of less than 0.018 cm after 500 hours at 71.degree. C. The plastic sheet remains substantially wrinkle free by the use of such silicone edge sealants.

[ That which is claimed is:] [1.] A sealed insulating glass unit comprising at least one flexible, heat shrunk plastic sheet between parallel, spaced glass panes, each sheet being substantially parallel to but spaced from confronting surfaces of the panes or another plastic sheet and being fixed at its edges with respect to edges of the panes, a silicone edge sealant between adjacent edges of the panes to provide an integral sealed unit, at least two opposing edges of the unit having each plastic sheet embedded into the silicone edge sealant, where said silicone edge sealant exhibits a sheet creep of less than 0.018 cm after 500 hours at 71.degree. C.
