Glazing unit spacer technology
First Claim
1. A multi-pane glazing unit comprising first and second panes maintained in a spaced-apart configuration by a spacer located between the first and second panes, the glazing unit having at least one between-pane space with a width, the first and second panes having confronting surfaces exposed to said between-pane space, the between-pane space being a gas or vacuum gap located inwardly of the spacer and defined by the confronting surfaces of the first and second panes such that the between-pane space is devoid of another pane, the spacer having a length and a width, the width of the spacer corresponding to the width of the between-pane space, the spacer having two side regions defining opposed ends of the spacer that are sealed respectively to said confronting surfaces of the first and second panes, the spacer having an engineered wall that extends across the width of the between-pane space so as to be substantially perpendicular to said confronting surfaces of the first and second panes, wherein the engineered wall, in moving widthwise along the engineered wall, comprises multiple corrugation fields including a first corrugation field and a second corrugation field, the first corrugation field having a first set of widthwise corrugations, the second corrugation field having a second set of widthwise corrugations, said first set of corrugations comprising corrugations that are sized differently than corrugations of said second set of corrugations, said first set of corrugations having a greater corrugation height than said second set of corrugations, such that a single wall of the spacer has multiple corrugation fields that respectively have differently sized corrugations, said single wall of the spacer being the engineered wall.

- 1. A multi-pane glazing unit comprising first and second panes maintained in a spaced-apart configuration by a spacer located between the first and second panes, the glazing unit having at least one between-pane space with a width, the first and second panes having confronting surfaces exposed to said between-pane space, the between-pane space being a gas or vacuum gap located inwardly of the spacer and defined by the confronting surfaces of the first and second panes such that the between-pane space is devoid of another pane, the spacer having a length and a width, the width of the spacer corresponding to the width of the between-pane space, the spacer having two side regions defining opposed ends of the spacer that are sealed respectively to said confronting surfaces of the first and second panes, the spacer having an engineered wall that extends across the width of the between-pane space so as to be substantially perpendicular to said confronting surfaces of the first and second panes, wherein the engineered wall, in moving widthwise along the engineered wall, comprises multiple corrugation fields including a first corrugation field and a second corrugation field, the first corrugation field having a first set of widthwise corrugations, the second corrugation field having a second set of widthwise corrugations, said first set of corrugations comprising corrugations that are sized differently than corrugations of said second set of corrugations, said first set of corrugations having a greater corrugation height than said second set of corrugations, such that a single wall of the spacer has multiple corrugation fields that respectively have differently sized corrugations, said single wall of the spacer being the engineered wall.
- 22. A spacer for a multi-pane glazing unit, the spacer having a length and a width, the spacer having an engineered inner wall, an outer wall, and two side walls, the engineered inner wall extending in a widthwise direction, wherein the engineered inner wall, in moving in said widthwise direction along the engineered inner wall, comprises multiple corrugation fields including a first corrugation field and a second corrugation field, the first corrugation field having a first set of widthwise corrugations, the second corrugation field having a second set of widthwise corrugations, and wherein said first set of corrugations comprises corrugations that are sized differently than corrugations of said second set of corrugations, the corrugations of said first and second sets being elongated in a direction substantially normal to the two side walls of the spacer, said first set of corrugations having both a greater corrugation height and a lower corrugation frequency than said second set of corrugations, such that a single wall of the spacer has multiple corrugation fields that respectively have corrugations of different size and frequency, said single wall of the spacer being the engineered inner wall.
