Insulating spacer for creating a thermally insulating bridge

Abstract From the Canadian patent

An insulating spacer creates 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 leg members, a bottom bridge member and a channel portion. The top bridge member contacts 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. The first and second leg members are embedded by crosshead extrusion into 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 …
