A multi-sheet glazing unit includes a closed spacer frame, the spacer frame has one side having a pair of legs joined to a base to provide the spacer frame with a U-shaped cross-section. An inner sheet has an edge mounted in an edge receiving member mounted between the legs of the U-shaped side of the spacer frame. The remaining edges of the inner sheet are within the interior of the closed spacer frame and spaced from the spacer frame. The inner sheet is held within the spacer frame by sheet retaining members mounted to the spacer frame. A sheet e.g. glass sheet is secured by a moisture-impervious adhesive to outer surface of each of the legs of the spacer frame. One type of sheet retaining members has a horizontal member and a vertical member, and a locking member. The locking member is mounted on the horizontal member spaced from the vertical member to form a groove to hold the inner sheet within the closed interior of the spacer frame. Another type of the sheet retaining member includes a pair of flexible fingers mounted on a platform member, angled away from the platform member toward one another and having their ends spaced from one another to provide a groove to hold the inner sheet within the closed interior of the spacer frame. A method for making the unit is also disclosed.

Multi-sheet glazing unit and method of making same

A multi-sheet glazing unit includes a spacer frame having a pair of legs joined to a base to provide a U-shaped cross-section. A sheet e.g. glass sheet is secured by a moisture-impervious adhesive to outer surface of each of the legs of the spacer frame. A plurality of sheet retaining members in a spaced relationship to one another are maintained on the legs of the spacer frame between the glass sheets and spaced from the base. The sheet retaining members each have a groove for receiving edge of a sheet e.g. glass sheet to secure the sheet between the outer sheets. The sheet retaining member includes a first part having a vertical stop and a non-vertical platform e.g. horizontal platform and an elongated securing member detachably secured on the horizontal platform spaced from the vertical stop to form the groove. A method for making the unit is also disclosed.

Multi-sheet glazing unit having a single spacer frame 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

Magnetic forces are applied to a side of a spacer frame mounted on a glass sheet to maintain the side of the spacer frame in alignment i.e. the plane containing base of the spacer frame perpendicular to the plane containing the surface of the glass to which the spacer frame is adhered. Thereafter a glass sheet is mounted on the other surface of the spacer frame. The sheets are adhered to the spacer frame by a sealant layer. After the sheets are assembled, the sheets are urged toward one another to flow the sealant to seal the space between the sheets.

Device for and method of aligning and/or maintaining a side of a 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. 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.

Low thermal conducting spacer assembly for an insulating glazing unit

A spacer stock and/or spacer frame having a pair of spaced outer legs joined by a base has a strengthening member integral with the base or an insert between the legs to reduce the degree of torsional twist of the spacer stock and/or spacer frame. In one embodiment during the forming of the spacer stock a 'T' shaped member is formed integral with the base to reduce the degree of torsional twist.

Spacer for an insulating unit having improved resistance to torsional

A multi-sheet glazing unit has a pair of outer glass sheets spaced from one another and secured to a spacer frame having a generally U-shaped cross section defined by outer legs secured to a base. The recess of a sheet retaining member is mounted on peripheral edge portions of an intermediate glass sheet. The intermediate glass sheet and sheet retaining member are mounted within the outer legs of the spacer frame to position the intermediate sheet between and spaced from the outer sheets. A method of making multi-sheet units is also disclosed.

This invention relates to a novel multiple-glazed vision and spandrel panel having vision and spandrel areas integral thereto, and a curtainwall system incorporating at least a plurality of these panels.

Multiple-glazed combination vision and spandrel architectural panel and

Force applied to marginal edge portions of a panel by opposed walls of a groove of curtain wall system is measured by mounting a pair of spaced blocks in the groove. Moveable jaw members are mounted in space between the blocks and moved apart into engagement with walls of the groove until the distance between outer surfaces of the jaw members is approximately equal to the width of the blocks. Thereafter, the force applied to the jaw members is measured.
