An insulating spacer for creating a thermally insulating bridge between inner and outer panes of, for example, a multiple pane window unit. The spacer defines an insulated space between the panes and includes a top bridge member, first and second metallic leg members, a bottom bridge member and a channel portion. The top bridge member is provided for contacting the inner and outer panes of the window unit. The top bridge member is made of a synthetic resin or composite material and can include openings. Perforated extensions of the first and second leg members are secured to the top bridge member. The first and second leg members can be bent into a zig-zag configuration. The bottom bridge member is substantially parallel to the top bridge member and cooperates with the first and second leg members. The channel portion is defined by the configuration of the top bridge member, the first and second leg members and the bottom bridge member. In one embodiment, the bottom bridge member is roll-formed from the same piece of metal as the first and second leg members. In another embodiment, the bottom bridge member is formed from a material similar to, or the same as, that of the top bridge member. Methods of making such an insulating spacer also are disclosed.
