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 soli d rubber and the glass panes. The fiberglass cord (24) is nonstretchable so th at 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).
