Insulating spacer for creating a thermally insulating bridge

A method of making an insulating spacer for spacing apart panes of a multiple pane unit, said method comprising the steps of:

• forming metal into first and second leg members of a metallic channel, the first and second leg members having extensions on one end thereof and the extensions being perforated;
• preheating the first and second leg members of the channel near or above the melting point of one of a synthetic resin material and a composite synthetic resin material;
• forcing together the extensions of the first and second leg members of the channel and the one of the synthetic resin material and the composite synthetic resin material, to secure the extensions of the leg members to the material such that the material forms a first bridge member across the leg members;
• and
• defining a channel portion of an insulating spacer by a configuration of the first bridge member, the first and second leg members and a second bridge member.

A method of making an insulating spacer having a width approximately equal to the desired space between panes in a multiple pane unit, said method comprising the steps of:

• forming metal into first and second leg members, the first and second leg members having extensions on each end thereof, the extensions of the first and second leg members being perforated;
• preheating the first and second leg members near or above the melting point of one of a synthetic resin material and a composite synthetic resin material;
• and
• forcing together the extensions on each end of the first and second leg members and the one of the synthetic resin material and the composite synthetic resin material, to secure the extensions of the leg members to the material such that the material forms first and second bridge members across the leg members.
