  • Low thermal conducting spacer assembly for an insulating glazing unit and method of making same
    Publication number: 20040163347
    Abstract: An insulating unit has a pair of glass sheets about an edge assembly to provide a compartment between the sheets. The edge assembly has a U-shaped spacer made of metal, metal coated plastic, gas and moisture impervious polymer, or gas and moisture impervious film coated polymer. The outer legs of the spacer and the glass provide a long diffusion path to limit the diffusion of argon gas out of the compartment. The edge assembly has materials selected and sized to provide edge assembly having an RES-value of at least 75.

  • Method of making an insulating unit having a low thermal conducting spacer
    Patent number: 6223414
    Abstract: A method of fabricating an insulating unit includes the steps of: providing a pair of sheets and a substrate; forming the substrate into at least one spacer section having a base and a pair of outer legs connected to the base, the spacer section having a surface designated as a supporting surface; providing a bead on the supporting surface, the bead provided on the supporting surface includes a moisture pervious adhesive having a desiccant therein and assembling a spacer frame that includes the at least one spacer section and the sheets provide an insulating unit having the pair of sheets in a fixed relationship.

  • Method of making spacer stock
    Patent number: 5761946
    Abstract: A flat elongated substrate having a bead of a gas and/or moisture pervious adhesive having a desiccant is moved along a predetermined linear path between spaced upper wheels aligned with spaced lower wheels. The upper wheels have a peripheral groove to shape the bead as the substrate moves between the upper and lower wheels. The lower wheels each have a U shape peripheral groove with the base of the U of the downstream wheels being narrower than the base of the U of the upstream wheels and the depth of the U of the downstream wheels being deeper than the depth of the U of the upstream wheels to provide a spacer stock having a base connected to a pair of spaced upright legs such that the base connected to the legs have a generally U shape configuration and a shaped bead on the surface of the base between the legs. The spacer stock may be bent to form a spacer frame to separate outer sheets of an insulating glazing unit.

The outer legs of the spacer and the glass provide a long diffusion path to limit the diffusion of argon gas out of the compartment. The edge assembly has materials selected and sized to provide edge assembly having an RES-value of at least 75. A spacer for use in insulating units includes a plastic core having a gas impervious film e.g. a metal film or a halogenated polymer film. Also taught herein are techniques for making the unit and spacer.
