Abstract: A spacer construction for insulating glass for windows comprised of thin sheets of metal, such as stainless steel, formed with a first bottom side panel wherein the first bottom side panel joins first and second spaced, typically diverging, lateral side walls or panels. A second inside wall of the spacer assembly is spaced from the bottom side of the first section or channel and joins, typically by welding, to the lateral side walls of the first section thereby forming a tube or chamber into which desiccant may be placed. A cushion material layer is positioned over and on the bottom side panel and is covered by a polymeric sheet affixed or bonded to the lateral sides to form an internal chamber filled with desiccant. The desiccant is positioned to impact against the film or sheet bonded to the bottom side panel and at least a portion of the lateral side walls of the channel enabling the assembly to effectively accommodate bending forces and stress upon bending of the spacer.

Abstract: A spacer for a sealed unit is formed of a stretched elongate strip of material, such as metal. The elongate strip is longitudinally stretched, causing a reduction in the thickness of the material. Stretching is performed by applying a tension across a segment of an elongate strip. The tension can be applied to the elongate strip by passing the elongate strip through at least two spaced sets of rollers. A first set of rollers operating at a first speed engages with the elongate strip and a second set of rollers operating at a second speed applies a tension to the elongate strip to cause stretching of the material. Corrugated rollers can also be used to form the material into an undulating shape.

Abstract: A key member or key for joining muntin or spacer bars in a dual pane window include an insertion end for frictional engagement in the open ended passage of a spacer bar and a projection end comprised of axially extending, spaced prongs that include teeth or serrations that enable interlocking with projecting prongs of a like key member.

Abstract: An integrally molded window spacer bar connector for joining opposed spacer bar end passages in the form of a hollow tube with a longitudinal axis of symmetry and a transverse axis of symmetry includes inclined leading edge ramps, a medial rib to control the insertion of the connector into spacer bars, and external channels to receive a sealant material for sealing the connector to the spacer bar at the seam of the joint of the spacer bar.

Abstract: A unitary connector for connecting hollow muntin bars transversely includes one end with barbed projections or hooks which engage openings in the planar sides of the tubular muntin bars and which also include an opposed plug which engages the hollow open end of a muntin bar. The connector includes laterally extending tabs to engage opposed panes of glass.
