Method of manufacturing a multiple-pane insulating glass assembly characterized by the steps of (a) Forming a substantially sealed integral unit comprising supporting a flexible, heat-shrinkable plastic sheet between parallel, spaced glass panes, the sheet being substantially parallel to but spaced from confronting surfaces of the panes and being fixed at its edges with respect to edges of the panes; and (b) Heating the unit to cause the plastic sheet to shrink and become taut and wrinkle-free between the panes. Method of manufacturing a multiple-pane insulated glass assembly comprising the steps of (a) Providing a pair of glass panes; (b) Attaching an elongated spacer to one surface of each pane about the periphery of the pane, each spacer having a generally flattened, continuous surface lying in a plane parallel to but spaced from the surface of the pane to which it is attached, and the spacer attached to one pane being congruent to the spacer attached to the other pane; (c) Supporting between the flattened surfaces of the spacers a heat-shrinkable plastic sheet and providing a sealant between adjacent edges of said panes to provide an integral substantially sealed unit; and (d) Heating the integral unit to cause the heat-shrinkable plastic sheet to shrink and to become taut and wrinkle-free between the glass panes. Method of manufacturing a multiple-pane insulating glass assembly comprising the steps of: (a) Forming a substantially sealed integral unit comprising a pair of spaced, parallel glass panes and a heat-shrinkable plastic sheet substantially parallel to the panes but spaced equidistant from confronting surfaces of the panes, the sheet being fixed at its edges with respect to edges of the panes; (b) Heating the unit to cause the plastic sheet to shrink and to become taut and wrinkle-free between the panes, and then cooling the unit, the glass panes protecting the plastic film from temperature extremes during the heating and cooling steps. The multiple-pane insulating glass assembly produced by the method of claim 1.
