Abstract: An insulating glazing includes a first pane, a second pane, an inner spacer frame arranged between the panes, which, together with the panes, delimits an inner interpane space, a surrounding outer spacer frame arranged between the panes, which is arranged on the outward facing side of the inner spacer frame, wherein the inner spacer frame consists substantially of a first hollow profile spacer and the outer spacer frame consists substantially of a second hollow profile spacer, the inner spacer frame and the outer spacer frame are in each case connected together to the first pane and the second pane via a primary sealant, an outer interpane space between the outer side of the outer spacer frame and the first pane and the second pane is filled with a secondary sealant.

Abstract: A spacer for insulated glazings includes a polymeric main body including two pane contact surfaces, a glazing interior surface, an outer surface, and a cavity, wherein the polymeric main body contains a thermoplastic polymer as a base material at a proportion of 30 wt.-% to 70 wt.-%, as an elastomeric additive, a thermoplastic elastomer, and/or a thermoplastic terpolymer having an elastomeric component at a proportion of 0.5 wt.-% to 20 wt.-% in total, and a reinforcing agent at a proportion of 20 wt.-% to 45 wt.-%, the thermoplastic polymer as a base material includes a styrene-based polymer, and the polymeric main body has a foamed pore structure.
