The extruded aluminum spacer frame for insertion between the light-transmitting plates of an insulating-glass pane is formed with one or more pairs of transversely extending aligned openings for admission of a gas into the space within the confines of the frame, for evacuation of a gas from such space, or for regulation of the pressure within the space. If the openings are to be sealed, a tough elastic sealing compound is introduced by way of one opening of each pair so as to form in the internal space of the frame a block which sealingly contacts the inner side of the frame all the way around both openings of the respective pair. A plug is thereupon threaded or driven into one of the openings and close to or even into the other opening in order to urge the mass of sealing compound into sealing contact with the frame around both openings as well as to be maintained in sealing contact with the adjacent material of the compound.

A spacer frame for insulating-glass panes, comprising a tubular body defining an internal space and having at least one opening which establishes communication between said space and the exterior of said body; a mass of tough elastic sealing compound confined in a portion of said space in the region of and sealingly surrounding said opening so that the opening is sealed from the reminder of said internal space, said compound having a prefabricated hole in register with said opening; and a plug removably extending into said hole by way of said opening and establishing a seal with said compound, said compound exhibiting a tendency to contract against the plug in said space.
