Two glass panes are separated by a so-called core spacer (10) made of either EPDM rubber or another solid rubber material with a centrally positioned fiberglass cord (24) extending longitudinally therethrough for imparting strength to the core spacer (10). The EPDM rubber formulation is chemically compatible with hot melt butyl which is used as an adhesive between the solid rubber and the glass panes. The fiberglass cord (24) is nonstretchable so that the core spacer (10) does not deform or break apart when the core spacer (10) is either initially manufactured or later placed between the two glass panes (32, 34).

Deux panneaux vitrés sont séparés par un élément d'espacement central (10) en caoutchouc EPDM ou en autre matériaux caoutchouteux solides, un cordon en fibre de verre (24) s'étendant longitudinalement dans ce dernier, de sorte qu'une certaine résistance soit conférée audit élément (10). La formule du caoutchouc EPDM est compatible au plan chimique avec le butyle thermofusible qui est utilisé comme adhésif entre le caoutchouc solide et les panneaux vitrés. Le cordon en fibre de verre (24) ne peut être étiré, si bien que l'élément d'espacement central (10) ne se déforme pas ou ne casse lors de sa fabrication initiale ou lorsqu'il est placé entre les deux panneaux vitrés (32, 34).
