A spacer for use in connecting the edges of two or more panes of insulating glass, panel walls or the like. The spacer is extruded as one material and is formed with retaining lips (external and internal). The present invention improves actual window systems by having an innovative shape of material providing a precise thickness, a new technique of spacer frame preparation, novel external lips to increase the strength of assembly and being capable of being utilized in most of todays multi-pane glazing assemblies. The body of the spacer is made of Polyvinyl chloride(PVC) with an appropriate mineral type filler providing better insulation, ease of production techniques and low cost of production. Together these innovations provide exceptional insulation, adhesion characteristics and weather resistance when utilized with proper sealant and desiccant material.
