A substrate having a bead of a moisture and/or gas pervious adhesive having a desiccant therein is shaped to provide U-shaped spacer stock. The spacer stock is bent to provide a spacer frame having continuous corners.

Spacer and spacer frame for an insulating glazing unit and method of making same

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 an insulating unit having a low thermal conducting spacer

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.

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. 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.

Spacer and spacer frame for an insulating glazing unit and method of

A vacuum insulating unit has a pair of glass sheets spaced from one another by a plurality of plastic supports. The supports have one end secured to one of the sheets and a low friction material on the other end. A flexible metal edge retainer is secured to sheets to provide a sealed compartment between the sheets. Air in the compartment is removed to put the compartment under negative pressure. A getter is provided in the compartment to adsorb any gas therein during sealing or using the unit. One of the sheets may have an environmental coating. Methods are disclosed for fabricating the unit and the supports.

Vacuum insulating unit

A sheet transporter has a rectangularly shaped frame having a sheet receiving surface, a pair of sheet retainers mounted adjacent the top corner of the frame to maintain the sheets toward the sheet receiving surface, laterally moveable sheet support member adjacent bottom corners of the frame and a lifting bail having an adjustable elongated member mounted to the frame with the longitudinal axis of the elongated member and sheet receiving surface of the frame subtending an oblique angle.
